GS7
Often a valve is required which under normal conditions is closed and perfectly tigh but, if necessary, it could be opened remote control: pinch valve G.S.7 meets these requirements since it features the automatic spring closing system and double control (handwheel and hydropneumatic cylinder) for the opening system.
