Description

Valve fully opened:
1, Too large a differential pressure and a low downstream pressure may result in damage to the valve by cavitation.
2, To avoid it, refer to the differential pressure in two or more stages by installing and connecting directly two or more control valves in tandem.

The same main valve structure is used for all types of control valve.

We suggest extending the exhaust tube to places where the relief water will not pouufe the surrounding or damage other devices, especially electrical apparatus.
