Why Use Safety Valves? Introduction to Safety Valves

05 March 2022

A safety valve is one of the important mechanical devices used in several industrial applications to protect systems from overpressure. Excess pressure build-up in the system can cause explosions, fires, and damages to critical components and products.

Safety valves are designed to stop these problems by reducing or removing excess pressure from the system. They are specially designed to be actuated by the fluid being controlled; hence, it works when pneumatic or electronic safety controls fail.

Below, we have covered more about safety valves: types, working principles, applications, selection criteria, and everything in between.

Safety Valve Working Principle

The general working mechanism of safety is simple. When the pressure of a system exceeds the maximum allowable working pressure (MWAP), safety valves quickly open to remove the excess pressure before it even builds up. These valves are fast-acting, and they open fully until the system pressure comes back to normal.

Most safety valves have a smaller inlet port and a larger discharge outlet. This ensures that any overpressure can be quickly corrected without damaging the sensitive machine parts. The detailed working principle of safety valves from opening to closing depends on the design and application of the valve. We’ve highlighted more on this below.

Types of Safety Valves and Use Cases

There are three main types of safety valves. These are:

Spring-loaded safety valves
Pilot-operated safety valves
Safety valves with balanced bellows

a. Spring-loaded Safety Valves

This is one of the most common types where the valve is held closed by a spring, and the balance between the input force and the spring force determines the closing and opening of the valve.

Most spring-loaded valves used in everyday applications come with a flat poppet valve, but those designed for specific liquids and gases come with varying valve shapes. Some even come with a lifting chamber that provides more lift, reducing the time it takes to eliminate the excess pressure in a system.

Spring-loaded valves for vapor and gases often open before the MWAP is reached, and the valve is lifted at least 50% at the MWAP.

The problem with this type is increased backpressure that interferes with the safety of the valve. Backpressure is defined as the pressure that builds upon the outlet of the safety valve as the fluid medium flows out. Most spring-loaded valves are available for pressure ranges between 1 bar and 1400 bar.

b. Valves with Balanced Bellows

This type of safety valve comes with metallic bellows that increase the poppet valve’s surface area. The benefit to this is reduced backpressure hence more safe operation. The spring mechanism is also isolated from the fluid media; thus, there’s no undesirable influence on the spring force. That said, most valves with balanced bellows are designed to handle backpressure not exceeding 16 bar.

c. Pilot-operated Safety Valves

A pilot-operated safety valve has its popper valve held onto the nozzle by the inlet pressure, helping avoid leaks or undesired openings. When the inlet pressure is lower than the maximum working pressure, the safety valve will always remain open.

However, as soon as the inlet pressure goes beyond the response pressure, the valves open instantly, allowing the media to flow and reducing the pressure. As soon as the pressure comes back to normal, the valve closes.

All three types of safety valves find applications in different industrial settings. Some of the common areas where safety valves are used include oil and gas, manufacturing, food processing plants, refineries, pressure booster systems, and more.

Choosing a Safety Valve

Before picking a safety valve in the flooded market, you should always consider the following:

The response pressure or the maximum allowable working pressure.
The backpressure at which the valve can operate without causing safety issues.
The discharge capacity of the safety valve.
The valve’s operating temperature.
Valve and sealing material.

Besides the above factors, you should also check the certifications required for your specific industry. For instance, safety valves used in the oil and gas industry will vary significantly from those used in the beverage and food industry. Some of the common certifications and standards in the market include ASME, TUV, and ISO 4126.

Summary

A safety valve is an important mechanical device that helps solve the problems associated with overpressure. There are three main types of safety valves: spring-loaded valves, pilot-operated valves, and those with balanced bellows.

When the inlet pressure is higher than the maximum allowable working pressure, safety valves open up to avoid pressure build-up. This, in turn, avoids damages, fires, explosions, and injuries.

The right choice of safety valve will largely depend on your unique needs. Some of the critical factors to consider are response pressure, operating temperature, seal and valve material, discharge capacity, and backpressure. You may also want to do thorough research before choosing a safety valve from a given manufacturer.

For instance, check the manufacturer’s reputation, warranty, industry experience, customer reviews, etc.

Typically, these establishments use power-driven machines and materials-handling equipment to process their raw materials or contract with other manufacturers to do so for them. Top Manufacturing Industries Of 2023 According to Fladger Associates, these manufacturing industries contributed more than $218 billion in sales to the state's gross state product last year. 1. Apparel & Leather Apparel & Leather is one of the oldest and most widely produced manufacturing industries in the world, producing a wide range of goods, including footwear, bags, and garments. Its trade is presently over US$ 80 billion annually. Leather, which is a natural or synthetic material created from animal hides, is popular for its durability and fashion. Its use has been around for centuries, dating back to the Ice Ages, and continues today to offer protection from harsh weather conditions. The apparel & leather manufacturing industry comprises establishments that produce full lines of ready-to-wear and custom clothing. These establishments include apparel contractors performing the cutting or sewing operations through the materials which are owned by others, jobbers who perform entrepreneurial functions involved in apparel manufacture, and tailors who manufacture custom garments for individual clients. 2. Chemical Products The chemical industry produces an immense number of products that impinge through virtually every aspect of any of the lives. Most of the chemicals produced by this industry are sold directly to consumers, but some are used as intermediates in manufacturing processes. For example, many of the basic chemicals produced by the petrochemical industry are used as raw materials in making plastics and other goods that are sold by other companies. Safety must be a high priority in the chemical manufacturing industry. The products produced can be flammable, explosive, corrosive, and toxic, requiring the use of high pressures and temperatures to prevent accidents. This is why the chemical industry operates within the safety limits demanded by national and international legislation. 3. Food & Beverage The food & beverage industry manufactures and distributes fresh foods, packaged foods, and beverages (alcoholic and non-alcoholic). It also includes companies that provide catering services and transportation services. The manufacturing industries are an essential part of the economy, accounting for 5% of the GDP and 10% of employment in the United States. It is also a growing market. Profit margins in the food and beverage industry have decreased recently, but they should improve as commodity prices fall. Additionally, food is a necessary part of life and will continue to be so for years to come. Several companies have been promoting healthy eating habits and offering products that are good for you. These are a part of the effort to make food less harmful for consumers while still maintaining quality and taste. 4. Fabricated Metals Almost every object we encounter in our daily lives has gone through a metal fabrication process. It’s impossible to imagine the modern world without this vital industry. Fabricated metals are products fabricated from raw materials, typically sheet metal that can be formed into a variety of sizes and shapes. This includes everything from small engines and car frames to windmill blades and alternative energy sources. Fabricators have a wide range of processes and machinery that can create custom metal products with precise dimensions, intricate designs, and specialized finishes. From cutting and stamping to bending and coating, each piece is a unique project that requires different tools and techniques. 5. Machinery Machinery refers to equipment used in manufacturing, such as stamping presses, robotic welders, and automated conveyor systems. This equipment needs to be perfectly calibrated and maintained in order to perform their tasks efficiently and correctly. Alternatively, the word machinery can be used to describe all machines, whether they are in a factory or on a farm. Specifically, machinery, in this sense, refers to machines that are powered by electricity or natural forces. The 10 manufacturing industries include establishments engaged in the mechanical, physical, or chemical transformation of materials, substances, or components into new products. These establishments include plants, factories, and mills. 6. Petroleum & Coal Petroleum and coal are exhaustible natural resources that are used to make heat, lighting power, machine lubricants, and feedstocks for other chemicals and plastics. They are also used as a base for many other manufacturing industries products that we use in our everyday lives, such as refrigerants, aerosols, antifreeze, detergents, dyes, alcohols, explosives, and more. Fossil fuels are naturally occurring materials that have been formed by geological processes over millions of years. These include coal, which is a rock that was formed from dead plant life that lived and died hundreds of millions of years ago, and petroleum, which is a liquid form of fossil fuel that was formed from plants and animals that live in lakes and oceans. 7. Transportation Equipment The transportation equipment manufacturing industry produces a range of machinery that provides the means to transport people and goods. This includes motor vehicles and parts, aircraft, ships and boats, railroad rolling stock, and other miscellaneous equipment. Establishments in this subsector use production processes similar to those of other machinery manufacturing establishments, including bending, forming, welding, machining, and assembly. However, with the assembly of components and subassemblies, their further assembly in a finished vehicle tends to be a common production process in this industry group, which is a much larger number than any of the other machinery manufacturing industries. This sector is a vital component of the transportation industry as it manufactures and builds various equipment needed for road, air, and water transport. It also plays a crucial role in the construction industry, where pieces of heavy equipment need to be transported from an excavation site to a construction area. 8. Paper Products Paper products are manufactured by pulp and paper mills, which produce raw materials that are converted into a wide range of paper types. Common paper types include kraft paper, construction paper, and newsprint. Pulp is produced from wood chips by mechanical or chemical processes that break down the lignin, a substance that makes up cellulose fibers. The resulting material is a thick, strong, and flexible substance that is typically coated with additives to increase its strength for printing or writing. The paper is then pressed and dried to make it into paper sheets. Depending on the manufacturing industry's type, it may also be coated with coats of various chemicals that provide a glossy finish. Calendaring is also a critical step in the paper manufacturing process. This process enhances the surface properties of paper as it passes through a series of drum-type rolls. 9. Textile Mills Textile mills produce a wide range of cloth products. These products are often woven, knitted, or printed. These industries have changed the way people dress and decorate their homes. They also created vast new support industries and transportation and information networks. For example, the textile manufacturing industries are responsible for creating the cotton sheeting and shirting fabrics that were so popular during World War I. The United States entered the war with a high demand for any kind of cloth and outfit for American troops, and many Georgia mills won government contracts for production. However, the disjuncture between the mill owner's desire to give the maximum effort. Also, the mill workers, who desire to regulate for themselves the pace of their work, lead to serious labor tensions. Those tensions are helping spark the beginnings of union activity in textile areas across the South. By 1900, ninety-five locals had been organized. 10. Wood Products Wood is one of the most abundant and versatile natural materials on earth. It has been used by humankind since its earliest beginnings and continues to play important roles in fuel, food, building, and transportation and as a raw material for many chemical products. Despite competition from metals, plastics, and other materials, wood still plays an essential role in society. It is a renewable resource with the potential for management in a sustainable manner that minimizes environmental damage. Wrapping Up In North America, various federal and state agencies regulate forest management and timber conversion to promote the wise, efficient use of resources. The industry has also developed various certification systems that provide third-party assurance of adherence to stringent manufacturing and sound environmental principles. In addition, electronic tracking is adopted by some wood companies to improve transparency in their supply chains of the manufacturing industries.
