Micro resistance counter weight soft close check valve
This counter weight nozzle buffer swing check valve is a valve which is automatically opened and closed by the flow of the medium itself and used to prevent the reverse flow of the medium,and eliminate destructive water hammer.
1.Light valve disc, opening in big way, the remarkable electricity saving, low flow resistance
2.The design of water hammer elimination is novel
3.The sealing is stable, wear resistance, long service life, no vibration, no noise.
