Micro resistance slow closing check valve is a kind of valve.It can be used in the drainpipe line of clean water, sewage and seawater, which can not only prevent the backflow of the medium, but also effectively limit the destructive water hammer and ensure the safety of the pipeline.
Characteristics:
Not suitable for media containing solid particles and high viscosity.
The butterfly check valve is characterized by novel structure, small size, light weight, small fluid resistance, reliable sealing, stable opening and closing, wear resistance, long service life, oil pressure, slow closing is not affected by the medium, and has better energy-saving effect.HH46X HDH48X HH49X series micro resistance slow closing butterfly check valve has been widely promoted and applied in various industries, such as urban construction, and the response is good.
