G3F 3-way Control Valve

The Clorius G3F 3-way control valve is designed for hot water and hot oil systems and can be installed in pipe systems as mixing or diverting valves. The G3F control valve is used in conjunction with our temperature regulators for controlling industrial processes, district or central heating plants or marine installations.

The 3-way control valve components – spindle, seats and cone – are 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. The thread for the actuator connection 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).

Without an actuator being installed, connection A-AB is fully open and connection B-AB completely closed, by means of 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 B-AB is fully open and connection A-AB completely closed.

The valve characteristics are as follows:
Port A-AB and AB-A: quadratic
Port B-AB and AB-B: almost linear

These characteristics ensure constant total flow under almost all pressure conditions and optimum circulation in the individual circuits.
