Application of Proportion-air Electric Proportional Valve in Vacuum Control of Leak Test

 

The proportional air RMV and QB2 can be used for high flow leak testing vacuum control applications. The higher flow capacity allows for faster fill and exhaust times, which will increase throughput and reduce testing costs.

In this application, the QB2/RMV vacuum assembly can accurately control the vacuum of the mold cavity under test. Once the vacuum level is reached in the tank, a shut-off valve (not shown) is activated and the tank is tested for leaks. If there is a leak, the analog output of the sensor will start to drop, and the controller will measure the leak and determine the quality of the tested component. This is a 2-loop configuration where the QB2/RMV component directly (inline) controls the vacuum in the mold cavity by becoming a restriction in the line.
