1. Summary

The hydraulic safety valve test benches of model YFS-A series are used to perform  set pressure(popping) test and seal test on safety valves. The test benches are steady in performance, self-contained in outfit, and easy in operation. The main outfit of the test bench includes gas(air) vessel, precision pressure gauges, gas(air) fine filter, gas(air) pressure reducing valve and so on. In addition, all the pipeline and needle valves of the test bench are made of stainless steel. As for testing high pressure safety valves, the test bench can be equipped with a gas(air) booster pump imported from the USA. With this pump, safety valves with nominal pressure for 32.0Mpa can be tested. The test bench can be particularly designed and manufactured according to customers′ special requirements. By the way, the protective measures need to be settled by customers themselves.
