HC41X muffling check valve is suitable for water supply system to prevent the backflow of media on the pipeline, the Department of realization of one-way flow of media, there is pressure to the spool, so that the spring is compressed, the valve quickly open, when the media flow in the reverse direction, the spring pushes the spool pressure to the seat, the valve that is closed. HC41X muffling check valve of the special design to ensure that the valve works smoothly, no vibration and noise when closing, eliminating other forms of water hammer sound produced when closing. The special design of HC41X muffler check valve ensures smooth operation of the valve, no vibration and noise when closing, eliminating the water hammering sound produced by other forms of check valve.
Product Application
Used for all valves that prevent backflow of media in piping systems.
Working Principle
This valve to the center of the guide shaft differential pressure shuttle principle and spring assisted rapid (in advance) closure, pump start, the full water flow channel, reduce flow resistance, so that the system for effective work.
