G2F 2-way Control Valve (DN100-DN150)

The Clorius G2F 2-way control valves (DN100…DN150) is designed for use in regulating high-pressure hot water, steam and heat transfer oil. The valves are used in conjunction with temperature or pressure differential regulators for controlling district or central heating plants, industrial processes or marine installations.

Design

The valve components – spindle, seats 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. The connection thread for the actuator is G1B ISO 228. The valves are double-seated. The leakage rate is less than 0.5% of the full flow (according to VDI/VDE 2174).

Function

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.
