Pressure Relief Valve Buying Guide

Pressure relief valves are critical components in any equipment or system that involves pressure or containment of fluids, gases or steam. These valves are designed to protect the equipment, piping or vessels from the damaging effects of overpressure and are essential for ensuring the safety and efficiency of the system.

Choosing the right pressure relief valve is crucial for the proper operation of the equipment and to avoid potential safety hazards. In this guide, we will discuss the key factors that you need to consider when buying a pressure relief valve.

Purpose and Application

The first thing you need to identify is the purpose and application of the pressure relief valve. Different applications require different types of valves and different pressure settings. You need to consider factors such as the fluid or gas medium, temperature, pressure range, flow rate, and whether the valve is used for liquid, gas or steam service.

If you are unsure about the specifications and requirements of your application, it is advisable to consult a technical expert or valve manufacturer to ensure that you select the right valve for your application.

Valve Type

There are different types of pressure relief valves available in the market. Some of the most common types of valves are:

  • Spring loaded safety relief valves
  • Pilot operated safety relief valves
  • Pressure reducing valves
  • Pressure vacuum relief valves
  • Diaphragm valves
  • Relief valves with bellows

The type of valve you choose depends on the application and the system requirements. For example, spring loaded safety relief valves are commonly used in low to medium pressure applications where the discharge capacity is low, while pilot operated safety relief valves are used in high pressure applications where the discharge capacity is high.

Capacity and Sizing

The capacity of the pressure relief valve should be capable of handling the maximum flow rate of the system or equipment. If the valve capacity is too low, it may not be able to handle the full flow rate, which can result in excessive pressure buildup and damage to the system.

When sizing a pressure relief valve, you need to consider the required capacity, the set pressure, back pressure, and discharge piping size. The valve capacity is typically expressed in terms of the maximum flow rate in cubic meters per hour or per minute.

You can use valve sizing software or consult the valve manufacturer for guidance on the correct sizing of the valve based on your system requirements.

Set Pressure

The set pressure is the pressure level at which the valve opens to relieve the excess pressure. This is a critical factor that needs to be carefully considered when selecting a pressure relief valve.

The set pressure should be set below the maximum allowed pressure of the system or equipment, and it should be high enough to prevent premature opening of the valve due to normal operating variations in system pressure or temperature. The set pressure is typically expressed in PSI, bar or kilopascals.

Material Selection

The material selection is an important consideration when selecting a pressure relief valve. The valve should be made from materials that are compatible with the fluid or gas medium and the operating conditions of the system.

Common materials used for pressure relief valves include stainless steel, brass, carbon steel, and bronze. Some applications may require the valve to be coated or lined with a specific material to resist corrosion and ensure long-term performance.

Seal and Seat Material

The seal and seat material of the pressure relief valve should be selected based on the compatibility with the fluid or gas medium and the operating conditions of the system.

Common seal and seat materials include Teflon, Viton, Nitrile, and EPDM. The selection of these materials can affect the reliability, durability, and the overall performance of the valve.

Certification and Standards

Pressure relief valves must meet certain standards and certification requirements to ensure that they are safe and reliable for use in the intended application.

The most common certifications and standards for pressure relief valves include ASME, API, ISO, and CRN. It is important to select valves that are certified and meet the relevant standards to ensure that they are reliable, safe, and perform as intended.

Manufacturer and Vendor Selection

Selecting a reputable manufacturer or vendor is crucial when buying a pressure relief valve. You need to ensure that the manufacturer has a proven track record of quality and reliability, and that they provide robust technical support and after-sales service.

The vendor selection is also important as it can affect the delivery time, pricing, and the level of support that you receive. You should choose a vendor who has a broad range of products and can provide you with the technical expertise and support that you need.

Conclusion

Selecting the right pressure relief valve is critical for ensuring the performance, safety, and reliability of your system or equipment. You need to consider factors such as the valve type, capacity, sizing, set pressure, material selection, seal and seat material, certification and standards, and manufacturer and vendor selection.

By following these guidelines and working with a reputable manufacturer, you can find the right pressure relief valve that meets your application requirements, and helps you to avoid potential safety hazards and equipment damage.
