This regulator is among domestic models for industrial and commercial applications. Compared to GS-74-27 , it enjoys higher incoming pressure range and outflow capacity.
Features:
- The operation is unilateral and It never starts up with exerting pressure into the outlet.
- In case of the flow changes at the inlet, the outflow remains constant.
- If the outgoing flow is stopped ( Q=0 ) with maximum incoming pressure , the regulator goes on normal operation and the blocked pressure would not exceed the specified limit.
- The regulator can be installed under different positions wih the possibility to rotate the diaphragm casing in an angel of 360 to the body.
Safety equipment installed on Gas Souzan’s GS-74-27H regulators is:
According to the NIGC’s orders and in order to increase safety level for consumers , three safety systems are considered in this regulator.
- Shutting off gas flow in case of the outlet pressure drop-lower than the specified limit (LPSO).
- Shutting off gas flow in case of the outlet pressure ise beyond the specified limit (HPSO)
- Automatic relief valve for case of gas flow overpressure.
