YQ98001(20001) filter adjustable pressure reducing valve：

YQ98001 filter pressure reducing valve is an intelligent valve that uses the energy of the medium itself to adjust and control the pipeline pressure. When the valve is supplied with water from the inlet end, the water flows through the needle valve into the main valve control room, and the outlet pressure acts on the pilot valve through the conduit. When the outlet pressure is higher than the set value of the pilot valve spring, the pilot valve closes. The control room stops draining, at this time the pressure in the control room of the main valve rises and the main valve is closed, and the outlet pressure no longer rises. When the outlet pressure of the valve drops to the set pressure of the pilot valve spring, the pilot valve opens and the control chamber drains downstream. Since the displacement of the pilot valve system is greater than the water intake of the needle valve, the pressure in the control chamber of the main valve drops. Inlet pressure opens the main valve. In a steady state, the water intake and drainage of the control chamber are the same, the opening of the main valve remains unchanged, and the outlet pressure is stable. The outlet pressure does not change due to the change of the inlet pressure, nor does it change due to the change of the outlet flow of the main valve, so the outlet pressure can be safely and reliably maintained at the set value. The valve has precise decompression, stable performance, safety and reliability, convenient installation and adjustment, and long service life. It can be used in domestic water supply, fire protection system and industrial water supply system.

YQ98002 (20002) filter safety relief valve

YQ98002 over-cleaning safety pressure relief valve is installed on the pipelines of high-rise buildings, fire water supply systems and other water supply systems. When the pressure in the water supply pipeline exceeds the set pressure of the pressure relief valve, the pressure relief valve will automatically open and quickly release the pressure to protect the safety of the pipeline. , It can also be used as a pressure sustaining valve to ensure the water supply pressure upstream of the main valve. The YQ8002 filter piston safety pressure relief valve produced by our company can accurately maintain a constant safety set pressure. Once overpressure, the pressure relief valve opens quickly to release pressure in time. YQ98002 filter piston type safety pressure relief valve, closes smoothly and reliably, eliminating pressure aftermath.
