YQ20001-16/25Q Water pressure reducing valve adjustment , DN 40-1200mm

  YQ20001-16/25Q  Water Pressure Reducing Valve Adjustment, DN 40-1200mm Product Description Working principle: The pressure P1 of upstream shall enter into the upside of piston control chamber through ball valve and control valve. And the upside of piston control chamber will communicate with downstream through pressure reducing pilot valve and control valve. The underside of piston control chamber communicates with the outlet. The downstream pressure P2 shall be set through adjusting bolt of pressure reducing pilot valve. When upstream pressure P1 and flow are varying, the opening of main valve can be controlled by fluctuation of piston of sensitive components regulated by pressure reducing pilot valve so as to ensure P2 to be constant   Application:  This kind of valve is widely used in piping system for waterworks, fire prevention, petrochemical industries and power plants. The upstream higher pressure can be made to meet the downstream pressure requirements.     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
