Relay Valve Test Bench:-

The Relay Valve is used to apply the effective braking, which is independent to brake cylinder volume. The objective of our test bench is to test the Relay Valve. In this test bench we use 1 Proportional Valve, 3 Pressure sensors. There are total 5 tests (Leakage Test [1] + Functional Test [4]) which can be performed on the test bench. This is a fully Automatic Test Bench and after placing the relay valve on the test bench all test will perform in a sequence automatically.

This test bench is used to test 2 different type of Relay Valves. In this test bench we can perform the test like Leakage from R to C in the presence and absence of Cv, Charging and Venting of C rapidly, Charging C step by step in the presence of Cv. During the test one can observe the waveform and test results are updated on the screen. After completion of the test, the waveform with report has been saved in PC.
