THE PRESENT INVENTION USES A REGULATOR (17) IN THE FORM OF DISPENSING CHECK VALVE AND A FLOW RESTRICTION ARRANGEMENT TO PROVIDE A VIRTUALLY FAIL SAFE SYSTEM FOR PREVENTING HAZARDOUS DISCHARGE OF FLUID FROM A PRESSURIZED CYLINDER OR TANK. A DIAPHRAGM (25) CONTROLS THE MOVEMENT OF ACHECK VALVE ELEMENT (19) TO PREVENT DISCHARGE OF GAS FROM A TANK UNLESS A PREDETERMINED VACUUM CONDITION EXISTS DOWNSTREAM OF THE CHECK VALVE. A CAPILLARY TUBE (13) OR OTHER STRUCTURE THAT PROVIDES CAPILLARY SIZE OPENING MINIMIZES ANY DISCHARGE OF GAS IN THE UNLIKELY EVENT OF A FAILURE OF THE REGULATOR. THIS SYSTEM IS PARTICULARLY USEFUL IN THE DELIVERY OF ARSINE GAS AND PROVIDES MULTIPLE SAFEGUARDS AGAINST ACCIDENTAL DISCHARGE.FIGURE 2
