Manual Type

Pneumatic Type

GS6

These valves feature a double pressure cylinder for the remote controlled, either pneumatically or hydraulically, closing operation; they do not feature any hand control. The opening operation is automatically controlled by suitable springs housed in the pressure cylinders; all operations are simultaneous and symmetrical to the centreline of the sleeve; in this instance, therefore, no flexible coupling for teh remote control line is required.

This valve is used for large flow diameters and has all moving parts enclosed in a suitable case.
