Butterfly simple structure, small space required for installation

Butterfly simple structure, small space needed to install, easy to operate, with good regulation  2 way manifolds  can be achieved quickly open and close and flow resistance loss when fully open, so widely used. Valve installed in the pipe conduit not only for on-off control, but can also be used for adjusting the flow and pressure pipe. Project  Instrument valve manifolds  aqueduct design, according to the formula in the design flow of hydraulic lines calculated in line with the actual situation, and under low flow conditions calculated residual pressure line there is a big head. Qin Qing Ji to lead pipes, for example, long-distance water pipelines partially completed in phases according to the city water needs.
