XYQ20002-1.6/2.5 MPa Piston Safety Pressure Relief Valve, DN 40-1200mm

XYQ20002-1.6/2.5 MPa Piston Safety Pressure Relief Valve, DN 40-1200mm   Product Description Working principle: The upstream pressure P1 shall enter into the upside of piston control chamber through pilot valve and control tube. The upside of piston control chamber will communicate with downstream through pilot valve and control tube to the outlet of valve. The opening pressure shall be set by adjusting the bolt of pilot valve. When the piping system pressure exceeds the predetermined pressure, the pilot valve then opens up. The main valve will be following opening to vent piping system pressure, therefore ensuring the safety of piping system and making safety pressure relief.    Structure features  l  Accurate pressure set, endurable and stable; once exceeding the predetermined pressure, the valve can quickly relief pressure.  l  Resilient seating and reliable sealing.  l  Y-pattern wide valve body, low fluid resistance, strong anti-cavitation capacity and no noise.  l  Stable and reliable piston transmission,  l  Installation at any angle.  l  Both inner and outer surface are coated with environmentally friendly coatings to ensure corrosion resistance and safety.  l  Pressure relief mechanism adopts pilot type construction to control on/off of the main valve. The capacity of pressure relief is greatly improved owing to its precise calculation and design. Convenient and flexible operation with large scope of modulating and reliable.    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
