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.

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.

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.
