How to Choose the Right Pressure Relief Valve

Pressure relief valves are intended to keep plants running easily and securely. They ensure vessels' funneling frameworks and different kinds of gear from hazardous overpressure circumstances. However, not all pressure relief valves are made for each plant. 

Certain applications require a particular sort, and when an inappropriate part is introduced, the plant can encounter difficult issues and danger everybody's wellbeing. That is the reason it is essential to choose the right pressure relief valve for your particular framework.

To assist you with picking the right pressure relief valve for your plant, here is a rundown of factors you should consider. 

Valve Materials 

Pressure relief valves come in various metals. Each metal is intended to oblige explicit applications. Contingent upon the framework, a valve made with a specific material might be expected to guarantee wellbeing and legitimate activity. For instance, hardened steel pressure relief valves have properties that permit them to work best in plants with destructive materials. 

Valve Design: Connection Size and Type 

Similarly, as each pressure relief valve is made with an assortment of metals, every valve likewise includes a particular plan with an unmistakable association size and type. As per the National Board of Boiler and Pressure Vessel Inspectors, the size of the valve must be in any event as large as the delta and release funneling. Furthermore, certain valves are intended for explicit connector types. 

Set Pressure 

The pressure relief valve is intended to withstand incredible measures of pressure and high temperatures, yet every gadget has its own particular cutoff points. The set pressure is the pressure that makes the valve open, and it's deliberate in pounds per square inch (PSIG). 

The National Board of Boiler and Pressure Vessel Inspectors express that the set pressure of the valve can't surpass the most extreme passable working pressure. However, a valve with a set pressure not exactly the greatest admissible working pressure is satisfactory. 

Back Pressure 

Backpressure, or the pressure on the outlet side of the valve from the release framework, will likewise add to the most extreme passable working pressure of the valve. This factor can be steady or variable to the plant's activity. Steady back pressure will require a pilot-worked valve. Variable valve pressure can't surpass 10% of the valve set pressure. 


Pressure relief valves can likewise withstand high temperatures. However, explicit metals can just deal with specific temperatures. So the temperature of the framework should be considered to guarantee legitimate valve determination. 

Required Capacity 

While pressure relief valves can mitigate a lot of pressure, they do have their cutoff points. The greatest limit of pressure they can calm relies upon numerous angles, including the plan of the valve and the temperature of the fluid or gas moving through them.

Aira Euro Automation is the Best Pressure Relief Valve Manufacturer in India, Aira has a wide range of pneumatic and manually operated industrial valves. They export their products in more than 20 countries including Gulf countries.
