Product Description

General

FREE VALVE Double Flanged Ductile Iron EPDM Disc Fluorine Lined Swing Check Valve relies on the flow of the medium itself automatically opens and closes the valve disc,which is an automatic valve used to prevent the reverse flow of the medium. The disc and the special stem are designed as a whole, the stem ring is embedded in the groove formed between the valve body and the valve cover, and the circular disc rotates around the special stem, the disc opens and closes flexibly and the seal is reliable.

 

Features

 

1. The disc is designed as a whole with special stem.
2. Easy to install,the valve can be used for horizontal and vertical installation.
3. The channel is in a flow line shape in the valve, and the flow resistance is smaller than that of the lift check valve.
4. The lining material is optional, which can be applied to a variety of media ,the valve has good corrosion resistance.
