Reducing with Check
In additional to providing a steady & lower downstream pressure against a high & fluctuating upstream pressure, the main valve also acts as a check valve. In the event that there is a reversal of pressure, ie, downstream pressure goes higher than upstream, the main valve will automatically go to close position thereby preventing a back flow. Optionally, speed control
to the check feature can be added.
