|
FEATURES :
- For Gaseous Media
- Inlet Pressure Range upto 4 Bar
- Adjustable Operating Pressure
- Free of Non Ferrous Metal

APPLICATION :
The Safety Relief Valve has been designed for:
- To reduce temporary pressure surges in the control system, especially downstream of Regulator, in order to avoid accidental operation of Safety Shut-Off Valve (SHV).
- To avoid a sudden pressure rise in case of gas leakages due to the inadequate closure of gas governors.
Specified for all gas pressure regulating plants with inlet pressure greater than 100 millibar, in conjunction with Safety Shut-Off Valve (SHV), according to the code of practice G490/491.Suitable for air technical combustion gas, bio-gas etc.
Also applicable as bypass governors. |
