PN 10 - Valves

The Clorius M3F 3-way Control Valve (DN80-DN150) is designed for regulating 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 valves are 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 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 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 A-AB is fully open, and connection B-AB completely closed using a spring. By increasing pressure on the spindle, the opening of the ports changes proportionally to the travel of the spindle. When the spindle is pressed to the bottom, connection B-AB is fully open, and connection A-AB completely closed. * If 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 L3F 3-way control valve is designed for regulating hot water – and cold and hot seawater. The L3F control valve is used in connection with temperature regulators in control systems for industrial processes or marine installations. The valve components – valve body, seats, cone and spindle – are made of seawater-resistant materials with connection flanges drilled according to DIN 86021. The connection thread for the actuator is G1B. 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 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.
