M1FBN 2-way Control Valve

The Clorius type M1FBN 2-way balanced control valve is designed for regulating hot water, steam and hot oil systems. Balanced valves are used in installations where the system pressure necessitates a closing force greater than available in the actuator programme for a standard single-seated valve, and where the leakage rate for a double-seated valve is unacceptable. The type M1FBN control valve is used in conjunction with our temperature or pressure differential regulators for controlling industrial processes, district or central heating plants or marine installations.

The Clorius type M1FBN 2-way balanced control valve is designed for regulating hot water, steam and hot oil systems. Balanced valves are used in installations where the system pressure necessitates a closing force greater than available in the actuator programme for a standard single-seated valve, and where the leakage rate for a double-seated valve is unacceptable. The type M1FBN control valve is used in conjunction with our temperature or pressure differential regulators for controlling industrial processes, district or central heating plants or marine installations.

Design

The valve components, spindle, seat and cone – are made of stainless steel. The M1FBN body is made of cast iron EN-GJS-400-15 with flanges drilled according to EN 1092-2 or ANSI B16.5 Class 150. The thread for the actuator connection is G1B ISO 228. The valves are single-seated. The leakage rate is less than 0.05% of the full flow (according to VDI/VDE 2174).

Function

Without an actuator being connected, the valve is held in an open position using a spring. With force on the spindle, the valve will close. In connection with our thermostats, pneumatic or electric actuators, the valves will close at rising temperatures. For cooling circuits, the valve can be used in conjunction with a reverse acting electric actuator. The quadratic characteristic will not cease until the flow has dropped below 4% of the full flow.
