Difference between Pressure Relief Valves and Pressure Safety Valves


A pressure relief valve is utilized to restrict the pressure in a framework inside a particular set level. Be that as it may, a pressure safety valve impels consequently to deliver extreme pressure. The alleviation valve opens just when the pressure arrives at the particular set pressure limit and is generally worked by an administrator. It doesn't need administrator help to deliver over-the-top pressure.


The closeness between the pressure alleviation valve and the wellbeing valve is that the two of them are spring-stacked valves. Typically, the valve is constrained closed by the spring. At the point when the pressure expands, the power of the spring has conquered that powers the valve to open.

Characterization of the Pressure Safety Valves

Safety Valves are fundamental for controlling the stream pace of liquid, subsequently working with the viable utilization of the framework and giving extra well-being to compressed vessels or frameworks. There are three sorts of Pressure alleviation Valves.


  • Safety valves: - A pressure valve that is utilized with compressible gases, steam, and air administrations.

  • Relief valve: - A valve that is utilized in a water-powered framework as pressure over ledge gadgets. They can additionally be customizable help valves and well-being alleviation valves. They are generally utilized in maritime boats for producing warm power.

  • Safety Relief valve: - A valve that is utilized either for fluid or compressible liquids in a compressed vessel is known as a wellbeing help valve. These are by and large utilized in boilers.


Grouping of Safety Relief Valves

  • Conventional(spring-stacked):- The principal parts of customary spring-stacked wellbeing alleviation valve are the spout, seat circle, plate holder, hat, spring, set pressure changing screw, body, and blowdown change ring.

  • The pilot worked:- The principal part of a pilot-worked water-driven valve is gulf from the framework, hole, fundamental spool spring, dart, pilot spring, change the screw, pilot channel, the skirt of the spool, and

  • Adjusted cries:- The fundamental parts of the Balanced how is alleviation valve are the spout, body, changing ring, circle, seating surface, roars, adjusted cylinder, hat, spring, changing screw, stem, and cap.
