Manual control threaded valve

Description

This valve is operated by line pressure by means of a 3 way selector valve, this selector has the positions “open”, “close” and “auto”.
In the “open” position the valve is fully opened, in the “close” position the valve closes slowly to avoid water hammer. “Auto” is used to receive external orders (from solenoid, pressure reducing pilot, etc.).

Applications

The valve opens and closes in response to a local pressure command.
It is possible to connect the vale to a remote pressure command.

Available models

1 ½”, 2”, 2 ½”, 3” and 4” BSP (NPT opcional)
