Sampling gas cylinder valve (stainless steel, Sulfinert treated)

Multi way valve configuration, including pointed tube and safety diaphragm

The large volume and durable Kel-F valve seat ensures no leakage during use.
Temperature range:- 40 °C - 120
°C
Alta Robbins' unique valve design features a soft seal seat for excellent durability and long service life. The valve has low torque and can be easily closed, while also being sturdy enough to withstand excessive twisting pressure.

Multi way valves can be used for high-pressure and ultra-high pressure sampling gas cylinders. A reserved volume tube or pointed tube provides a reserved volume for gas evaporation. When the temperature rises, the liquid in the cylinder can expand without a significant increase in pressure. Reserved volume is the evaporation space in a steel cylinder expressed as a percentage of the total volume of the cylinder. Reserved volume%=(evaporation space/total volume), with a large reserved volume of 50%. The pointed pipe is directly welded to the inlet external thread of the valve and cut to a length of 5.25 inches. The function of the safety diaphragm is to protect the sampling gas cylinder by releasing the gas in the cylinder into the atmosphere to prevent overpressure of the sampling gas cylinder. The pressure rating of the safety diaphragm is always lower than that of the gas cylinder.
