Bellow Seal Valve

Overview

The Bellow sealed globe check valve is a valve with two functions, which are globe and check valve. Connecting this valve’s stem and the disc is designed to open the structure. The stem can withstand the movement of the valve disc when it closes the valve, the disc sealing and seat sealing surface to achieve the close status. In the meanwhile, the valve can break off the media in the pipeline.

When opening the valve, the stem and disc are disengaged. It plays the role of a check valve to prevent the media backflow. This valve has a dual function, it can cost savings and higher security. Especially suitable for the installation location restrictions for special occasions.
