Top 7 Factors to Consider For Selecting the Best Safety Relief Valve

Safety relief valves or pressure relief valves ensure the safety of pipelines, vessels and equipment that deal with pressure-sensitive workflows. Unregulated pressure flow in such systems can lead to overpressure that can cause an explosion or cause damage to the machinery. To ensure the safety of personnel, equipment and other assets, you need to select the perfect valve from reliable safety relief valve manufacturers.

Here are the top 7 factors to consider while selecting a safety relief valve:

1. Size

Based on common usage, there are standard valve sizes offered by valve manufacturers. The orifice size should be selected as per the minimum required flow rate. You can pick a suitable inlet and outlet for the valve from the various size options available in the market. Valves are also available in flanged and non-flanged designs. Also, are you looking for a male or female connection? Filter your valve options as per the size requirements. If you are searching for a safety valve for specialised equipment then consider custom valve designs.

2. Set Pressure

A safety relief valve opens when it reaches the set pressure point. Ensure that your chosen valve comes with a set pressure as per your needs. Incorrect pressure settings may not give you optimum performance and can become a safety risk.

3. End Application

Safety valves are used in various industries. Based on the process fluids that will be passing through them, the valve material should be chosen. The valve should be able to function smoothly while allowing safe passage of elements such as air and water or process fluids that can be corrosive media.

4. Temperature

Many a time, the environment in which the safety valves are installed may involve extreme temperatures. You need to choose a safety valve that can withstand such high or low temperatures and does not interfere with the quality of the contents passing through it.

5. Capacity

Experienced safety relief valve manufacturers have standard valve capacity tables. Check if you can find a valve model with your desired capacity by referring to these tables. Else, you can think about customisation of the valves. Do not try to get a standard model if it doesn’t meet your capacity needs because it can be risky. The valve must relieve the process fluid at a certain capacity to serve its purpose.

6. Back Pressure

Depending on whether the fluid will move upstream or downstream, the back pressure needs to be decided. The back pressure is the pressure on the outlet side of the valve and can be constant or variable. Discuss your requirement with the valve manufacturer to get the back pressure right. If the back pressure isn’t right, the chances of getting the valve damaged quickly are high.

7. Quality

While you have got your tech specs right, the quality of your safety relief valve depends on the quality tests. Make sure that your chosen pressure relief valve manufacturers are able to provide you with all the quality test certifications guaranteeing the durability and safety functionality of the valves.

What is the purpose of a pressure relief valve?

There are several industrial mechanisms where pressure plays an important role. To control the pressure in many of these mechanisms, a pressure relief valve produced by safety relief valve manufacturers is sought.

Pressure Safety Valve (PSV), Relief Valve and Pressure Relief Valve (PRV) are different names of a safety valve, a component used for controlling pressure. The PSV is used mainly in industries such as chemicals, petrochemicals, natural gas processing, etc.

Ensure safety with a pressure relief valve

The pressure relief valve is a safety valve that keeps the pressure within safety limits to prevent equipment failure, mishaps or other undesirable outcomes. Pressure relief valves are designed with controls to increase or decrease the level of pressure in a pressure vessel.

The safety relief valve ensures safer management of the environment if excess of pressure or overpressure situation occurs wherein the pressure increases beyond the Maximum Allowable Working Pressure (MAWP). The excess pressure generated is diverted into a safer outlet through an auxiliary route.

An automatic safety relief valve also functions effectively in the absence of a power by tracking the process fluid movement in the pipeline. For example, even during a power failure, the LPG passing through a LPG pipeline can be automatically shut off with the help of a functional safety relief valve if excess liquid flow is detected in the event of a leakage in the line.

For the safety valve to deliver optimum performance, it should be installed and maintained properly. Use of a pressure relief valve with an incorrect size can also lead to damage to life and property in the vicinity. Pressure relief valve manufacturershave to run a number of tests to design and build the valves with the right specification.

Finding the right pressure relief valves

Depending on the contents to be passed through the valve, the material of the valve can be decided. Materials such as Stainless Steel, Brass and Carbon are some of the material options. Although there are standard valve sizes available in the market, the valve can be custom-designed along with desired end connection types to get the right fit for the intended mechanism.

Pressure relief valve manufacturers usually have a team of engineering design experts who discuss the requirement with the client for customised valve designs. Depending on the application, a pop action safety valve or angle type discharge valve can be used. The pressure range can be customised as per the specifications of the pressurized area. High quality pressure relief valves require low maintenance and therefore, lead to minimal costs.

For pipelines carrying LPG and other gases, safety risks are averted by using valves. Whether it is an industrial plant, a commercial space or a residential complex, reliable safety relief valve manufacturers are well-equipped with the necessary infrastructure and the teams to ensure minimum wastage of energy and maximum safety in handling of contents.

Certified valves are provided by expert manufacturers who study the requirements of the clients and offer a cost-effective solution with the necessary test certificates from industry-recognized certifying agencies. For reliable safety relief valves, get in touch with AEPL at www.aeplglobe.com.

What is the Purpose of a Safety Relief Valve?

Safety relief valves or the pressure relief valves are the devices that are used in almost every industry to give the machinery an ultimate security from getting damaged due to over-pressurization. The most efficient safety relief valve manufactures design the valves in order to cater the diversified needs of the different industries. They thrive to survive in the market by designing the tailored valves that exactly meet the specific demand of the clients.

Importance of the Safety Relief Valves

The safety relief valves are a very important aspect of an industry, as it offers protection to life as well as property. When a system operates, an amount of pressure builds in it as a result of multiple functions. Though the device depletes the developed pressure, the pressure relief valve gives an overall protection to the machinery from any catastrophic incident by opening an outlet. This releases the excessive pressure that makes the ambiance inside the system favorable for any operation. More than attaching a valve with a device, it is important to check the reliability and work ability to ensure its operation at the time of emergency.

The Need of the Safety Relief Valves

The safety relief valves are attached to the systems that have pressure as an important component. The valve starts operating when the pressure exceeds the set limit. The following are the reasons which contribute to the increase in pressure:

• Faulty cooling system, which results in the expansion of liquid or gas.
• Electrical power failure.
• Increase in compressed air.
• Fire in the plant.
• During the initiation of the industry.

The valves should be designed in a manner to meet the industrial needs that not only saves the system from any damage, but also ensures longevity. The valves may not function properly if they are not maintained, installed or correctly sized, leading to destruction.

Types of Safety Relief Valves

There are two types of safety relief valves available, which have different exhausting principle. One is the Pop action safety relief valve, which opens an outlet immediately after the pressure inside the system reaches the set limit, lowering the pressure. Another is the angle type discharge safety relief valve that gradually exhausts the pressure in order to make the built-in pressure normal. This also helps in regulating the flow of the liquid or gas along with the safety function.

Excess Flow Check Valve

The excess flow check valve makes sure the system is able to support a huge quantity of liquid or gas flow with a minimum pressure loss. This valve can be utilized in any position and is one of the best options for installing in lines. It functions efficiently in gas as well as in liquid and can be modified based on the client’s demands. It starts operating automatically when the pressure reaches the set limit or there is a fire.

Conclusion

The safety relief valve goes through various levels of checking and testing to ensure the accurate work ability at the time of emergency. The tough and tolerant material is used to manufacture the valves that are sufficient to withstand the extreme conditions of the operations. Therefore, if all the elements are used accurately in the manufacturing process, then the resultant valve will be sufficient to meet the extreme conditions.

Types of Pressure Relief Valves

Relief valves, which are also known as pressure relief valves are the unique type of safety valves that are used to bring the pressure of a system under control. Pressure is a very important aspect of any system which also has the capacity to upset the entire operation if not kept under proper control. The working principle of the pressure relief valves is to release the excessive pressure from a system by releasing the pressurized fluid through an auxiliary passage. There are numerous pressure relief valve manufactures in the market, but only a few of them meet the expected industrial standard.

Importance of the Pressure Relief Valves

An industry is built up of numerous machinery pieces that consist of diversified functions. It is very important to keep those in perfect working order to get the most out of it. Temperature and pressure are the criteria that drive the output in an effective way. Hence, it becomes essential to get in touch with one of the best valve manufacturers, who will supply the most efficient valve to protect the system from any harm. However, it is also essential to select the right kind of pressure relief valve in order to enjoy the proper functionality. Let’s have a look at the types of pressure relief valves available:

1. Safety Relief Valves

These valves keep the machines safe by releasing the excess pressure from it either immediately or gradually, depending on the requirement. There are two types of valves available with the safety relief valve manufacturers:

• Safety or pop-off valve – open an outlet completely when the set pressure exceeds, resulting in the excretion of the excess pressure through an additional valve.
• Angle type discharge valve – releases the pressure gradually when the pressure exceeds the set limit. Along with controlling the pressure, it is also effective in managing the flow in the system.

2. Excess Flow Check Valves

It is a spring impregnated check valve that either opens or closes depending on the velocity of the fluid flowing through it. The excess flow check valve manufacturers mainly design valves that are used in LPG, NH3, pipelines, road tankers and Propane storage tanks, which demand huge flow capacity valve with negligible pressure drop. It is suitable for both the liquid as well as gas and protects the system by automatically shutting down the process.

3. Ball Valves

It is a spherical closure device that is used to control the flow in a system. The competent ball valve manufacturers design the valves in such way that meets the industry standard in an efficient way. It uses the mechanism of rotational motion to shut or open the flow of liquid or gas. This type of valve doesn’t demand huge maintenance cost and is compact in size, making it easier to handle. This type of valve is preferred by all due to its low torque and quick tight sealing.

Conclusion

All the pressure relief valves have different mechanisms and are used in different fields to meet the diversified needs. Hence, one must consider the quality of the valves provided by the manufacturers to get the best deal on the market.
