M3F 3-way Control Valve (DN80-DN150)

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.
