 Piston Type Hydraulic Flow Control Valve with Flange Filtered PN 1.6/2.5MPa, DN 40-300mm; Flange PN 1.6/2.5/4.0 MPa, DN 40-1200mm Product Description   Among the same type of valves, there are four pillars of supporting ribs and bearing in the center of the valve seat and a stem going through. As the pictures showing in above, in addition to the hydraulic design of body, water flow has to bypass those barriers and will simultaneously form irregular vortexes, which will greatly increase flow resistance. Obviously the hydraulic control valve with this type of structure will cause higher flow resistance and head loss . The seat of YQ hydraulic control valve has no supporting ring, bearing or rib in the center of seat, full opening without supporting, so such structural design generates the lowest head loss.   l  Hydraulic cylinder piston actuation shall provide smooth and reliable operation. Due to its cushioning action, the noise is very low. It shall overcome the defects of diaphragms, for example, vibration, noise and easy abrasion caused by severe pressure and flow changes. Shown as the below picture    l  Three positioning guiding gear design which consists of piston, stem, and guiding shaft provides the switch with much more accurate and reliable characteristics. It overcomes vibration defects caused by one point positioning of other valves. The piston is sealed by standard double Y-pattern self-sealing rubber ring for drip-tight sealing. Built-in spring can effectively prevent vibration caused by abrupt pressure flow changes and automatically close the valve at zero flow to prevent flow from reversing. Hydraulic cylinder serves to cushion and reduce water surge or water hammer effect on pipelines.   l  As per Water and Wasterwater Design Regulations for Buildings, strainer shall be installed before control valve to meet drainage requirement. YQ filter hydraulic control valves reasonably put control valve and strainer combined together, reducing face-to-face dimension by 45% compared with general ones. Take DN 100 as an example, the length of YQ filter piston control valve is 415mm, but in general the total length of a control valve plus a strainer would reach 720mm. Obviously, the installation of YQ hydraulic control valve of DN100 can reduce the length by 300mm and weight by 20%. Besides, a joint is omitted to save cost thereby.    Main parts list and materials       Main Dimensions   Hydraulic Control Valve Series   Filter Piston Adjustable Pressure-reducing Valve (Flanged)  ZSJF***-SP-1.6/2.5(F)   Filter Piston Adjustable Pressure-reducing Valve (Grooved) ZSJF***-SP-1.6/2.5(FG)       Piston Adjustable Pressure-reducing Valve (Flanged) ZSJF***-SP-1.6/2.5   Piston Adjustable Pressure-reducing Valve (Grooved) ZSJF***-SP-1.6/2.5(G)   Piston Safety Pressure Relief Valve(Flanged) XYQ20002-***-16Q/25Q   Piston Safety Pressure Relief Valve(Grooved) XYQG20002-***-16Q/25Q Piston Slowly Closed Check Valve (Flanged) XYQ20004-***-16Q/25Q/40Q   Piston Slowly Closed Check Valve (Grooved) XYQG20004-***-16Q/25Q/40Q Filter Piston Remote Control Float Ball Valve (Flanged) XYQ98003-***-16Q   Filter Piston Remote Control Float Ball Valve (Grooved) XYQG98003-***-16Q   Piston Remote Control Float Ball Valve (Flanged) XYQ20003-***-16Q   Piston Remote Control Float Ball Valve (Grooved) XYQG20003-***-16Q Packaging & Shipping Polyethylene Bags---- Standart export carton----Wooden case or as per customers' requirement   Shipping:Seaworthy  30 days in normal after receipt of the order. 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
