G2F 2-way Control Valve

G2F 2-way Control Valve

8995

The Clorius G2F 2-way control valve is designed for regulating hot water, steam and hot oil systems. The double-seated G2F linear valve is used in installations where the system pressure necessitates a closing force greater than available in the actuator programme for a single-seated valve. The valve is used in conjunction with Clorius temperature or pressure differential regulators for controlling industrial processes, district or central heating plants 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 thread for the actuator connection 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.

H2FR 2-way Control Valve

H2FR 2-way Control Valve

9013

The Clorius H2FR 2-way control valve is mainly intended for the control of cooling systems. The H2FR valves are used in conjunction with temperature or pressure differential regulators for controlling industrial processes or cooling systems. As the reverse acting valves are held in a closed position using a built-in spring, the max. differential pressure, ΔpL, against which a valve can close depends on the spring. When opening the valve, the actuator has to overcome the spring force. The table in the datasheet shows max. allowable values of ΔpL as well as the max. allowable inlet pressures for opening the valves, p1max, for various actuator forces. Design The valve components “ spindle, seat and cone – are made of stainless steel. The valve body is made of cast steel GP240GH (GS-C25) with flanges drilled according to EN 1092-1. The thread for the actuator connection 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). Reverse acting Without an actuator being connected, the valve is held in a closed position using a spring. With pressure on the spindle, the valve opens. In connection with our actuators, the valves act as œcooling valves, i.e. they open at rising temperatures. The quadratic characteristic will not cease until the flow has dropped below 4% of the full flow.

H1F 2-way Control Valve

H1F 2-way Control Valve

9029

The Clorius H1F 2-way control valve is designed for regulating hot water, steam and hot oil systems. The H1F 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. Design The H1F valve components – spindle, seat and cone – are made of stainless steel. The valve body is made of cast steel GP240GH (GS-C25) with flanges drilled according to EN 1092-1 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). 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, electric or pneumatic 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.

M1F 2-way Control Valve

M1F 2-way Control Valve

9045

The Clorius M1F 2-way control valve is designed for regulating low, medium and high-pressure hot water, steam and lubricating oils. The M1F valve is used in conjunction with our temperature or pressure differential regulators for controlling industrial processes, district or central heating plants or marine installations. Design The valve components – spindle, seat and cone – are made of stainless steel. The valve body is made of cast iron EN-GJS-400-15 with flanges drilled according to EN 1092-2. 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). 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 electronic 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.
