valve actuator

VA-3000 series actuator is electronic mechanic product, and can be directly mounted on VB-3000 series valves.
It can also be mounted on other valves with different connectors.

Features

A low AC voltage reversible synchronous motor, with a magnetic clutch to ensure the long life service of the motor and gear train.
Action is executed through gear transmission.
Valve-moving position indicator.
An auxiliary switch and manual control are available as accessories (order separately)
RA or DA operating mode could be selected through jumper in proportional 0~10V or 4~20Ma DC control

Operation

Actuator is driven by reversible synchronous motor with magnetism clutch. Motor can create stable torsion at stopping condition depending on the magnetism effort, which is created by motor rotor and magnetism clutch. And the motor can stop at any position when there is no current pass through.
