GAS CYLINDER DISPENSING VALVE

摘要

A gas cylinder dispensing valve having an internal flow path provided with a pressure regulator. An isolation valve is provided within the flow path between the pressure regulator and a gas inlet of the valve and a flow control valve is provided within the flow path between the pressure regulator and a gas outle t to discharge the gas. Both isolation valve and the flow control valve can be manipulated by a single control knob which when set in an off position close s the isolation valve. The control knob can be rotated from the off position to select discrete, calibrated flow rates or an auxiliary position in which gas may be dispensed at a regulated pressure from an auxiliary outlet port.
