Abstract
A pinch-type isolation valve (10) is provided having an integrated, on-board reservoir (42) for storing a pressurized fluid capable of effecting the collapse of an internal sleeve (32) upon actuation of the valve. Valve (10) comprises an outer wall 16 and an inner wall (30) which define the pressurized gas reservoir (42). An actuator assembly (14) is provided to cause and direct a flow of pressurized gas from the reservoir (42) into a gas-receiving chamber (39) defined between the inner wall (30) and sleeve (32).
