The model is among Domestic gas regulator for home applications with outflow capacity higher than that of model GS-74-27 .
Features:
- The operation of this regulator is unilateral . It never starts up with exerting pressure into the inlet.
- 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-74-27 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. Of the distinguished advantages of this regulator is the independency of this regulator is the independency of the outlet pressure regulation system from the safety system. Changes in the outlet pressure regulation range do not lead to changes in the safety system regulation limit.
