The Clorius G1F 2-way control valve is designed for regulating hot water, steam and hot oil systems. The G1F control valve is used in conjunction with our temperature or pressure differential regulators for controlling industrial processes, district or central heating plants or marine installations.

The Clorius G1F 2-way control valve is designed for regulating hot water, steam and hot oil systems. The G1F control valve is used in conjunction with our temperature or pressure differential regulators for controlling industrial processes, district or central heating plants or marine installations.
The valve components – spindle, seat and cone – are made of stainless steel. The valve body is made of nodular cast iron EN-GJS-400-15 with flanges drilled according to EN 1092-2 or ANSI B16.5 Class 150. The thread for the actuator connection is G1B ISO 228. The valves are single-seated. The leakage rate is less than 0.05% of the full flow (according to VDI/VDE 2174).
Without the actuator being connected, the valve is held in an open position by means of a spring. With pressure on the spindle, the valve will close. In connection with our thermostats, pneumatic or electric actuators, the valves will close at rising temperatures. For cooling circuits, the valve can be used in conjunction with a reverse acting electric actuator. Alternatively, a reverse acting valve can be used with our self-acting thermostats. The quadratic characteristic will not cease until the flow has dropped below 4% of the full flow.
