Connection Method and Respective Advantages
Wafer type with back butterfly valve Along with different kinds of valve body, shaft, bush and other parts, the butterfly valve can be assembled by different requirements from customers. Advantage no-pin connection with automatic centring technology, not only segregate the medium and metal, but also improve the reliability of valve, in the same time, the operation torque largely lower than normal butterfly valve, easy to maintain, and service life will be increased fivefold than normal butterfly valve. Surface of valve adopting epoxy coatings, well appearance with highly corrosion resistance. Flow property tend to straight line, perfect regulation performance. Use soft seal structure, can achieve two way seal completely, gas leakage test result is zero. Wafer type no back butterfly valve The Valve belongs to our newest designed and developed items along with all features of normal Valve and provided with following advantages: Groove style connection between body and seat, to assure seat, body and disc connected accurately, lower the difficulty when installing, and completely solved the issue of seat distortion due to wrong installation. Groove style connection with high strength, prefect precision, more stable interference between disc and seat, further improved the seal performance of Valve. Groove location structure, basically eliminated the phenomenon of Valve seat creep while switching, improved service life and reliability. Adopting orthodrome broadside design, suitable for several of flange. Lug type LT model butterfly Valve Using flange thread connection, could be used for connecting pipeline or as draining side at the pipe ends. Valve body high rigidity, can bear higher pressure of pipeline, special for places require high safety factor, such as the fields of gas/oil, power plant, etc. Double flange rubber lining butterfly valve The valve designed according to large-scale pipe network requirements, side flange connection size in accordance with butterfly valve connection standard. High strength, safety factor & pipeline stress resistance. Valve seat adopting overall vulcanized body design, high tear and distortion resistance. Flange according to customers\' requirements, convenient for connection of handle, or electric & pneumatic driven.Adoption Standard
