Product Description

H41X energy-saving silencing check valve is suitable for water supply and drainage pipeline. The valve disc is guided by the center shaft at both ends of the inlet. It can be opened and closed flexibly and can be installed horizontally or vertically. The valve disc is loaded by spring, and its quick closing can effectively eliminate the water hammer, with good sealing performance and no noise. It has the advantages of small volume, light weight, small fluid resistance, fatigue resistance, long life and so on.

How it works

The disc of H41X energy-saving silencing check valve is guided by the central shaft at both ends of the import and export, which is flexible in opening and closing and can be fixed horizontally or vertically installed. The valve disc is loaded by spring, and its quick closing can effectively reduce the pressure of the water hammer, with good sealing performance and no noise. It has the advantages of small volume, light weight, small fluid resistance, fatigue resistance and long service life.
