ZSJF-SP-1.6/2.5 MPa Piston Adjustable Pressure Reducing Valve, DN 40-1200mm   Product Description The upstream pressure P1 shall enter into the upside of piston control chamber through ball valve and control tube. The upside of piston control chamber will communicate with downstream through pressure reducing pilot valve and control tube. The underside of piston control chamber communicates with the outlet of valve. The downstream pressure P2 shall be set by adjusting the bolt of pressure reducing pilot valve. When the upstream pressure P1 and flow are varying, the opening of main valve can be controlled by fluctuation of the sensitive components piston regulated by pressure reducing pilot valve so as to ensure the downstream pressure P2 to be constant.    Structure features l  Flexible operation, large scope of modulating and reliable. l  Excellent pressure reducing function, constant downstream pressure regardless of variation of upstream pressure and flow rate. l  Suitable for reducing both static pressure (gauge pressure) and dynamic pressure(velocity head); test pressure readout on jobsite with self-equipped vibration proof pressure gauge l  Double Y-pattern self-sealed rubber used in piston seal ring, long life service; l  Y-pattern wide valve body, strong anti-cavitation capacity and no noise. l  Both inner and outer surface are coated with environmentally friendly coatings to ensure corrosion resistance and safety. l  Precise pilot valve enlarges controlling, excellent pressure reducing ability, flow and pressure characteristics are much better than the same type of domestic counterpart l  Stable and reliable piston transmission, installation at any angle bsp; Stable and reliable piston transmission, installation at any angle       Technical parameters     Main Performance Parameters

It mainly depends on quantity and types of valve  Company Information   Guangdong Yongquan Valve Technology Co.,Ltd (YQ for short) was founded in 1982 and its headquarters is based in Foshan city, Guangdong province. YQ manufactures a broad range of valve products under the “YQ” brand.These valve products are designed for use in the toughest applications such as municipal water systems; water supply and drainage systems in high-rise buildings; fire protection systems; HVAC systems, and industrial water systems. YQ also manufacture valves for use in sea water, and other applications.   So far,YQ produces over 30 series, more than 5700 types of products, and over 50 of them are patented. Patented products are available in a wide range, including pressure reducing valves, pump control valves, gate valves, and backflow preventers, etc. The gate valve has been both FM approved and UL listed. Not only does the company have its products sell nationwide, but also they are exported to oversea countries. Up till now, YQ products have been applied in more than 400 water supply companies, 100 national key projects as well as 20 overseas projects. YQ products can be found in national key projects including the Bird Nest (the national Olympic stadium), the Water Cube (the national swimming center) and the national theater, as well as Guangzhou International Convention & Exhibition Center, etc. They are also exported to other countries, such as the U.S.A., Canada and Russia etc.   The company focuses on products’ technical development. The objective of the company is “to serve our customers with revolutionary valves”. A marketing strategy of product localization and globalization will be taken into account for the company’s long term sustainable development. For requesting more information, please visit our website on http://www.yq.com.cn/.      Contact Ways
