Abstract
A pinch valve for controlling the flow through at least two flexible hoses includes an actuating member by which one hose is pinched against an abutment. This abutment is yieldable against a spring bias and normally keeps the other hose pinched. When said one hose has been pinched, the abutment is moved against the spring bias by the actuating member in order to relieve said other hose.
