940E Series Electric Motor Control Valve

The Trerice 940E Series Control Valve uses a 24 Volt power supply (AC or DC) to proportionally stroke the valve via an electric motor drive actuator.

The actuator will drive the valve stem up or down (to open or close the valve) in relation to a factory set 2-10 Vdc input signal (field switchable to 4-20 mA) from a controller.

These electric motors can be specified to “fail-open” or “fail-closed” should a loss of control signal or actuator supply power occur.

Actuators are available in two sizes: “25” for standard applications and “26” which provides for increased close-off capabilities and is required for use on some larger size valves.

For optimal performance, the service conditions (medium, flow, temperature, inlet and outlet pressures) of the application must be considered when selecting a valve.

Please refer to the Valve Selection Section of this catalog. Consult the Valve Selection tables for the capabilities of a particular valve/actuator assembly.

Improper application may cause failure of the valve, resulting in possible personal injury or property damage.
