The WHA component cycling test system allows the performance of pressurized opening/closing endurance tests on various pneumatic components including cylinder valves, regulators, and valve integrated pressure regulators. The system allows pre-set opening and closing torque values with computer controlled pressurization, opening/closing, and vent cycles. Components may be tested in oxygen, nitrogen, or a custom gas mix up to 6,000 psig. Pneumatic component standards for valves and regulators such as CGA V-9, ISO 10297, and ISO 10524-1 require cycle testing of components. See Endurance Testing in the Custom Oxygen Testing.
