Insbud Controls Company Limited

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
