GALASSI & ORTOLANI GS27 Model Pneumatic Type Pinch Valve

Design Features

The pinch valve mod. Gs 25, consists of a cast iron or aluminium body (two pieces unit) and of a natural or synthetic rubber sleeve, suitable to
withstand passing fluids (acids – alkalines powders – cement – waste and industrial water – sludge).
Closing occurs by pressing of a compressed air operated cylinder acting on a pad which in turn squashes to full closure.
Valve’s peculiarity is lack of stuffing box and load loss.
LS microswitches can be applied to indicate valve’s position (open or closed) as opposed to other types of valves where direct input of air on sleeve does not allow it.
Rubber sleeve one-piece moulded, comprises due terminal flanges acting as coupling gasket.
