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.

The Clorius L3S 3-way control valve is designed for regulating freshwater, cold and hot seawater and lubricating liquids. The compact L3S valve is used in conjunction with temperature regulators in control systems for cooling and heating of domestic premises, district heating, industrial processes or marine installations. The valve components – valve body, seats and cone – are made of sea-water resistant gun metal RG 5. The valves are single seated. The leakage rate is less than 0.5% of the full flow (according to VDI/VDE 2174). Note: The design of the sizes DN 15 (½Ë) and DN 20 (¾Ë) is different from the bigger ones. Without an actuator being connected, connection 2-1 is fully open and connection 3-1 completely closed by means of a spring. On increasing pressure on the spindle, the opening of the ports changes proportionally to the travel of the spindle, and when the spindle is pressed to the bottom, connection 3-1 is fully open and connection 2-1 completely closed.

The Clorius S3FM-T is a three-way control valve with a slide for quarter-turn operation, designed for most industrial fluids and aggressive media. The valve body and the valve slide are made of stainless steel AISI316. The valve flanges are drilled according to EN 1092-2. Optional: ANSI, JIS and Grooved Victaulic Joints. Valves can also be supplied in AB-Left configuration and AB-Middle. The slide is firmly connected with the actuator spindle. When the slide is in the one outer position by turning the spindle, connection A-AB is fully open and connection B-AB is fully closed. In the other outer position, connection A-AB is fully closed, and connection B-AB is fully open. In the intermediate positions, the opening degrees change proportionally. The valve has a minimum gap between the body and slide. To minimize the leakage, an O-ring is mounted in a groove on the slide.
