Technical Parameters: Maximum drift diameter: DN400mm Maximum test pressure: 60Mpa Pressure test precision: pressure gauge of 0.4 grades (Users can choose a more precise one.) Test medium: nitrogen, compressed air or clean water (Gas liquid dual-capable one can be designed.) Functions and Characteristics: The equipment has advanced design principle. It uses pneumo-hydraulic booster pump as its clamping pressure source and air driven gas booster pump as its test pressure source. A gas cylinder is equipped, which enables the test to be conducted continuously. â?¢The test pressure is adjustable and the process of pressurization is stable. â?¢Clamping pressure source and test pressure source can use imported booster pumps from America or Germany, which have a wide range of output pressure. â?¢All the manual high pressure valves, pipe fittings and connectors are imported ones, which guarantee their pressure levels, safety and reliability. Most gas and liquid media are available. MAQ-400 /48BA Functions and Characteristics: Maximum drift diameter: DN400mm Maximum test pressure: 48Mpa Pneumatic control hydraulic clamping device is adopted. Clamping force is adjustable. The equipped pressure gauge displays the corresponding clamping force and provides a comparison table between the pressure and the clamping force, which facilitates operators to choose appropriate lamping force according to the safety valve calibration pressure and the drift diameter. All the valves, pipe fittings and connectors are made of stainless steel. The test is operated manually and operators record the data. The system includes two test and calibration tables. One is equipped with two clamping devices. There are totally three clamping devices: one is for safety valves of DN15-DN100; one is for safety valves of DN100-DN200; one is for safety valves of DN200-DN400. â?¢Various test tools are equipped to meet the needs of customers on different kinds of safety valves.

Valve Test Equipment Valve test equipment can be used for a variety of applications, such as intermediate and final inspections by valve manufacturers, testing of new valves on delivery, and routine or post-maintenance testing of valves in service. These include, for example, pressure testing of valve housings, leakage testing of valve seats, and set pressure testing of safety valves. Other components can also be pressure tested, such as tanks, motor housings, pump housings, pipe fittings, insulators etc. Special clamping devices may be required to clamp these test pieces. Structure and working principle Valve test equipment is composed of hydraulic system, electrical control system, high and low pressure water pump pressure supply device system, oil pressure, water pressure instrument system, control valve system, clamping workbench system and hydraulic medium storage circulating water tank. The test process and results meet relevant regulations and requirements. The valve test equipment adopts flange end face sealing, holding pressure claw to directly clamp the valve, and the back of the flange is compressed. The clamping mechanism is directly driven by the clamping oil cylinder of the clamping claw. The axial direction of the clamping claw can move forward and backward, which is not limited by the thickness of the flange. The radial movement is composed of oil cylinder and lever to realize the radial synchronous movement of each clamping jaw. The radial clamping jaw can move forward and backward. It is not limited by the diameter of valve flange. There is no external force on the test valve. The left end of the test bench can move horizontally left and right, and the pressure test is not limited by the structural length of the test valve; The right end can be turned over 90 degrees to facilitate the sealing and air tightness test of the valve. The high-pressure water pump is powered by the 4-7 bar air pressure system and automatically reverses through the electrical control reversing valve to make the high-pressure water pump work automatically and reciprocally. The water suction check valve and water outlet check valve are interchanged to continuously supply pressure to the tested valve to meet the pressure requirements of the tested valve. It is applicable to the high-pressure water seal test of 1.1 times the nominal pressure, the high-pressure water shell test of 1.5 times the nominal pressure and the low-pressure air tightness test of 4-7bar for flange valves.
