Hydraulic Fluid Power Connection Winner Couplings
Product Introduction
Quick-action couplings are used to join or separate fluid conductors quickly and without the use of tools or special devices. it is the best choice for the fluid transfer lines need to be connected and disconnected for operation or maintenance of equipment frequently.
Winner brand couplings have three types: WQA, WQB, WQF1 meet or exceed different ISO standard.
WQA meet ISO 7241 series A, WQB meet ISO 7241 series B, both series are used in a wide range of hydraulic fluid power systems, and have similar technological advantages, Series A is used predominantly in Europe and is preferred worldwide for agricultural and forestry machinery, Series B is used predominantly in North America and in the chemical industry. The connect thread end of WQA has BSP thread and NPT thread two types, and for WQB only NPT thread type.
WQF1 meet and exceed ISO 16028, this series flat face couplings are specifically designed for those applications where higher working pressure and no-spill performance are essential, it include aerial work platform for maintenance of high voltage power transmission line, construction equipment, agricultural machinery, road vehicle etc., the connect thread end of WQF1 has BSP, NPT, UNF, metric thread type.
