1. The valve hydraulic strength test stand consists of 3 channels, which are composed of high and low compressed air. The inlet air source compressed air pressure is 0.6-0.8MPa or 15MPa cylinder gas, hydraulic output is 3 channels, the pressures are: 3-15MPa, 20-45MPa, 50-100MPa. The test pressure can be outputed in two ways, independently and combinedly.

2. System working pressure≤100MPa, selection of internal thread structure.

3. The inlet and outlet of the system are all equipped with filters, the inlet filtration precision is not less than 10um, the outlet filtration precision is not less than 5μm; the inlet and outlet are all equipped with mechanical pressure gauges.

4. The test system is equipped with pressure gauge, and the test pressure gauge is set on the test stand.
