H3F 3-way Control Valve (DN80-DN150)

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.
