DN100...DN800, DN100__DN125__DN150__DN80 - 2-way Control Valves

The Clorius G3F Soft Seat 3-way control valve is designed for regulating water, lubricating oil and other liquid media. It can be mounted in the pipe system as either mixing or diverting valves. However, when mounting as a diverting valve, the pressure drop is increased, compared with mounting as a mixing valve*. The 3-way control valve is used in conjunction with Clorius temperature regulators for controlling industrial processes, district and central heating plants and marine installations. Design The valve components – seats and cone – are made of alubronze, the spindle is 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 connection thread for the actuator is G1B ISO 228. The valves have two balanced single seats and are designed for tight closure. The leakage rate is less than 0.5% of the full flow (according to VDI/VDE 2174). [Tight between port 1(AB) og 3(B) is optional.] Function Without an actuator being installed, connection 2-1 is fully open, and connection 3-1 completely closed using a spring. By 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.   * In case the valves are applied as diverting valves, the pressure drop will increase by 35% and the kvs-value will decrease by 14% as against mixing valves.

The Clorius H3F 3-way control valve (DN80-DN150) is designed for regulating hot water, lubricating oil and other liquid media and can be mounted in the pipe system as either mixing or diverting valves. However, when mounting as a diverting valve, the pressure drop is increased, compared with mounting as a mixing valve*. The H3F control valve is used in conjunction with Clorius temperature regulators for controlling industrial processes, district and central heating plants and marine installations. Design The valve components – seats and cone – are made of alu bronze, the spindle is made of stainless steel. The valve body is made of cast steel GP240GH (GS-C25) with flanges drilled according to EN 1092-2 or ANSI B16.5 Class 150. The connection thread for the actuator is G1B ISO 228. The valves have two balanced single seats. The leakage rate is less than 0.5% of the full flow (according to VDI/VDE 2174). Tight between port 1(AB) og 3(B) is optional. Function Without an actuator being installed, connection 2-1 is fully open, and connection 3-1 completely closed using a spring. By 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. * In case the valves are applied as diverting valves, the pressure drop will increase by 35% and the kvs-value will decrease by 14% as against mixing valves.

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.
