200X Pressure Relief Valve product details

200X Pressure Relief Valve (adjustable pressure reducing valve) Structural features and uses:

200X pressure reducing valve (adjustable pressure reducing valve) produced and sold by Baigang valve group, the main valve, pilot valve, needle valve, ball valve, miniature filter and pressure gauge Composition of hydraulic control system. When used, when adjusted after the outlet pressure, can automatically maintain a stable outlet pressure. Baigang valve group production and sales of 200X pressure regulating valve (adjustable pressure reducing valve) by the main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge hydraulic control system.When in use, when the outlet pressure is set, it can automatically maintain a stable outlet pressure.

200X pressure reducing valve utilizes pilot valve self-control, does not require other devices and energy, easy maintenance, high pressure control accuracy, pressure and flow by the import of small, reliable decompression and voltage regulator.

200X valve products are widely used in high-rise buildings, living areas and other water supply pipe network systems and urban water supply projects.

200X Pressure Relief Valve (adjustable pressure reducing valve) Working principle:
When the valve from the inlet side of the water, the water flow through the needle valve into the main valve control room, the outlet pressure through the conduit to the pilot valve. When the outlet pressure is higher than the set value of the pilot valve, the pilot valve is closed. Control room to stop drainage, then the main valve control room pressure and shut off the main valve, the outlet pressure is no longer increased.
When the valve outlet pressure drops to set the pilot valve spring pressure, pilot valve open, the control room to the downstream drainage. As the pilot valve system displacement is greater than the needle valve inlet, the main valve control room pressure drop. Import pressure to open the main valve. In a steady state, the control room water, the same drainage, the main valve opening unchanged, the outlet pressure is stable. Adjust pilot valve spring to set outlet pressure.
