Whether it is to improve the efficiency of MEP supplies or keep the plant operation running and smooth, the installation of a pressure relief valve is pretty vital. Pressure relief valve is a type of safety device that is used for protecting system’s equipment from over pressurized events.

Before you get in touch with the list of pressure relief valve suppliers, you need to know which pressure relief valve is suitable for your application. When it comes to selecting the ideal option for it, the sizing is a key factor that is required to be considered.

Without proper sizing, the pressure relief valve is unable to carry out its intended performance. Aside from sizing, there are other things that are important to be considered to make the right choice.

Keep reading till the end to learn all about them.

Valve Materials

The material with which the pressure relief valve is made of, must be considered when browsing through varied options. Pressure relief valves come in varied metals.

Each metal is meant to accommodate a particular application. Based on the system, the valve manufactured of a certain material may be required to ensure protection and proper operation.

For instance, a stainless steel made pressure relief valve has properties that permit them to function efficiently in plants that have concern of corrosion. Similarly, depending on the application, the valve material must be considered before making a choice.

Set Pressure

Pressure relief valves are engineered to resist great amounts of temperature and pressure. However, each device has its own specific limitations. The set pressure is that pressure which triggers the valve to open and is calculated in pounds per square inch.

According to the standard regulations, the set pressure of a pressure relief valve must not surpass the maximum acceptable working pressure. On the contrary, a valve with a set pressure lower than the allowable maximum working pressure is permissible for use.

Therefore, when choosing the pressure relief valve, it is vital to consider the set pressure to that of the valve's workable pressure to find the right option.

Temperature & Back Pressure

As mentioned earlier, the pressure relief valve is equipped to withstand temperature as well. But similar to pressure limitations, each valve has certain temperature limitations as well.

Especially when it comes to pressure relief valve metals that it is made of. Certain metals can only take on specific temperatures. Therefore, when choosing a pressure relief valve, the temperature of the system is required to be taken into account.

Additionally, the back pressure is another crucial consideration for the proper selection of pressure relief valves. Back pressure is meant to be the outlet side of the valve pressure from the discharge system.

This factor can either be variable or constant to the plant’s operation. Variable valve pressure must not go beyond 10% of the valve set pressure, whereas, the constant back pressure will need a pilot-operated valve.

These are a few key considerations that you need to keep in mind when looking through pressure relief valve suppliers.
