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. My company consistently committed to relying on scientific and technological innovation, continuous application of new technologies, new processes, new techniques, new materials to develop high quality new products, over the years for the natural gas, petroleum, chemical fertilizer, metallurgy, mining, electric power, papermaking, printing and dyeing, pharmaceutical, food, food, water supply and drainage, air treatment and heating and other industries to provide a variety of gas and hydraulic devices supporting the valve. A specification batch manufacturing, valve should be authoritative institutions entrusted to test the performance of the following: (1) the valve open-close torque under working pressure conditions; (2) under working pressure conditions, to make sure that the continuous opening and closing the valve closed tight times; (3) the flow resistance coefficient of valve in the pipeline condition detection. 1. Valve should be done before they go out the following tests: (1) the valve under open conditions, the body should be 2 times the internal pressure of valve working pressure value detection; (2) the closing of the valve, 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.
