safety valve or how many types of safety valves are there?

safety valve Safety valve is a special type of safety valve that protects and resists excessive pressure. When there is a pressure that exceeds the maximum allowable working pressure (MAWP) or the pressure that the system can accept. Safety valves open quickly compared to relief valves. When there is too much pressure, the valve is slightly opened all the way to allow the excess pressure to be drained as soon as possible.

How many types of safety valves are there?

Spring mechanism

It is the valve that is most commonly used. It is called a straight safety valve. because it will be closed by spring only It has a pressure range from approx. 1 to 1400 bar.

Balance bellows

It is a valve designed for the purpose of reducing the effect of back pressure. and protect the bonnet springs It is also a guide for the released fluid.

Pilot operated safety valve

It is a valve that controls the opening-closing of the main valve, commonly used with equipment that requires a high pressure relief area. High discharge pressure and equipment with very similar values
