The pneumatic valve test methods

A specification batch manufacturing, valve should be authoritative institutions entrusted to test the performance, the valve open-close torque under working pressure condition, under working pressure conditions, to make sure that the opening and closing times in a row, the valve closed tight in the pipeline under the condition of the flow resistance coefficient of detection. Valve should be done before they go out the following tests: valve in open conditions, the body should be 2 times the internal pressure of valve working pressure value detection; The closing of the valve conditions, both sides stand 1 respectively. Double valve pressure value, no leakage; But the metal sealing butterfly valve, leakage nor a value greater than the related requirement. Wuxi east technology co. , LTD. Is a collection of the control valve industry manufacturing, development, production, assembly, sales and service in the integration of science and technology enterprises, professional research and development of electric valve, pneumatic valves, hydraulic valves, pneumatic actuators and various kinds of complete sets of pneumatic valve. Our company produce all kinds of pneumatic ball valves, butterfly valves, plug valves, regulating valve, gate valve, globe valve, flat gate valve and pneumatic device or valve products.
