YQSTBF Series Anti-cavitation Hydrostatic Balancing Valve, DN 15-400mm, PN 1.6/2.5MPa

  YQSTBF Series Anti-cavitation Hydrostatic Manual Balancing Valve, DN 15-300mm, PN 1.6/2.5MPa Product Description Working principle:  YQ20017 Static Balancing Valve is a static hydro-working valve, having good flow characteristics, enabling proper flow allotment, and making quantitative flow, therefore effectively dealing with the indoor temperature about unevenly heating and cooling problem existing in heat supply (air-conditioning) system. As the static balancing valve having equipped with indicator, open locking device, and small pressure valve for flow measuring, it is only installed proper specifications of static balancing valves in each branch and users’ pipeline entries. Upon locking after once-for-all adjustment with special instrument, the total amount of water in the system could be controlled within a proper range so as to overcome the improper phenomenon of “large flow but small difference in temperature”. The static balancing valve becomes an ideal product used in heating system with highest medium temperature up to 100℃.       The balancing valve’s working ways include hydraulic automatic control and manual control but without extra conditions. The working temperature is normal one, with PN 1.6MPa or 2.5MPa, and the circumstance shall be clean and good.     Application: It is widely used in pipelines of central air conditioning system, water supply and drainage, fire protection, petroleum, and chemical and engineering, as well as industry and mining enterprises, etc., especially used in pump house of the central air-conditioning system.   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
