valve test bench(JWZ model for flanged valves/hydraulic valve test bench/valve test): The valvehydraulic test benches of JWZ series are used to perform intensity test and leakage test of all kinds of DN15-DN1000 flanged valves,such as gate valves,ball valves,globe valves, check valves etc. The test bench is effectively composed of four parts,that is,mechanical system,hydraulic system,electric system and testing media cycling system. The entire process of the emplacing and clamping ofthe tested valve is completely controlled by electric components and hydraulic components.The most important characteristic of this series test benches is: the benches have noeffect of external force upon the tested valve body, because the clamping jaw clamps directly on the flange of the valves. One sideof the benches can be moved, thus the testing performance wont be restricted by the structural length of the tested valves. When testing valves, clamp the flange on the both sides of the valves, pressurize to the necessary pressure value, then perform the intensity test for the body, bonnet and middle flange of the valves. The other side of the benches can be reversed by 90 degrees to perform leakage test and air tightness test.The models for user choosing: JWZ-100---DN15-100 JWZ-200---DN50-200 JWZ-300---DN80-300 JWZ-400---DN200-400 JWZ-500---DN250-500 JWZ-600---DN300-600 JWZ-800---DN500-800 JWZ-1000---DN600-1000 The maximal pressure of intensity test: 480Bar The maximal pressure of leakage test: 320Bar The test mediums: water,gas or oil We also have the other kind of valve test benches, if you need any further information, please feel free to contact with us.
