Ductile Iron WCB Pressure Reducing Valve For Water System

The 200X pressure reducing or called stabilizing valve (adjustable pressure reducing valve) consists of a main valve, a pilot valve, a needle valve, a ball valve, a micro filter and a pressure gauge to form a hydraulic control connection system. When in use, after setting the outlet pressure, valve Can automatically maintain a stable outlet pressure.

The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to keep the outlet pressure automatically stable. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid, resulting in different pressure losses, so as to achieve the purpose of decompression. Then rely on the adjustment of the control and regulation system to balance the fluctuation of the post-valve pressure with the spring force, so that the post-valve pressure remains constant within a tolerance range.

Water flow through the pressure reducing valve has a large head loss, but it is still energy-saving in general because it reduces the waste of water, makes the system flow distribution reasonable, and improves the system layout and working conditions. For the convenience of operation, adjustment and maintenance, the pressure reducing valve should generally be installed on the horizontal pipeline
