M3 Control Valve Normally Open (NO)

The M3Linear Flow, Linear Control (LFLC) piston valve features dual control chambers.

The piston is mounted in a special volute with control action parallel to the flow.

The M3 valve is manufactured from light-weight, durable, precision-molded Nylon12 GR (50% glass fiber). A polypropylene valve is available to meet special fluid requirements.


•Closed Position
◦Control pressure applied to the closing chamber, on both the front and back pistons, creates sufficient thrust to overcome the upstream pressure applied to the actuator, closing the valve.
•Open Position
◦Venting the closing control chamber while upstream pressure is applied to the actuator creates a force that opens the valve.
•Modulating
◦Control is applied by either venting or supplying fluid to the closed control chamber, providing a drive which enables the actuator to adjust to the required position, maintaining the preset parameter.
The M3 Series supports:
•DN50 - DN80
•DN80 in a Multi-Valve application: a manifold with two valves controlled by one pilot.
•Adjustable inlets and outlets for different pipe diameters with various connections to line.
