2.VALVE TEST 2.1 Material Test The material quality of valve will be rechecked one by one by means of spectrum analysis or other methods, and make markings.
2.2 Ball Test Every ball used in the valves will be check for its ball roundness.
2.3 Pressure Test The pressure test will be conduct after the assembly.
2.4 Balance Test The aim of this test is to check the balance of the two sides of valve.
2.5 Switching times Test This will be test from a batch of product samples.
