GS1
The G.S.1 model pinch valve is fitted with parts for closure by hand at balanced pressure, enabling closure to be made with only very slight deformation of the hose coupling, but allowing it to become perfectly cylindrical when the valve is fully open.?
?
The hose coupling (moulded in a single piece) has two end flanges which, without any extra packing, ensure a perfect seal between the valve packing and the pipe or receptacle to which the valve is fitted.
