| description | The present apparatus invention uses a pressure responsive valve element to provide a virtually fail safe system for preventing hazardous discharge of fluid from a pressurized cylinder or tank. A diaphragm controls the movement of the valve element to prevent discharge of gas from a tank unless a predetermined pressure condition exists downstream of the check valve. This system is particularly useful in the delivery of arsine gas and provides multiple safeguards against accidental discharge. |
