WebA check valve is an automatic safety device designed to allow fluids and gasses to flow in one direction and prevent reverse flow. Under pressure, fluids enter the valve at the inlet where they force the disc off the seat of the valve and exit through the outlet. Flow continues steadily as long as the pressure is maintained to keep the disc open. WebA pressure reducing valve is used for lowering and regulating water or air pressure between the upstream (inlet) and downstream (outlet) sides. We will discuss their workings in more detail a little later. In summary though, for a typical water installation: A PRV will sit in-line on a mains inlet pipe
