Anti-Pollution Cut off Check Valve with Atmospheric Vent (Model NO. GHS11X)

Conventional type anti-pollution cut off valve is composed of two non-return valves in tandem connection.

The safety type anti-pollution cut off valve features an extra drainage and pressure relief device at the secondary non-return system. In this way, even if two non-return sealings are broken at the same time, it still can prevent back flow. It is a safety device to prevent back flow pollution in pipeline of daily drinking water systems, keeping drinking water safe and healthy.

The system mainly consists of the valve body, inlet connector, disc, gasket, and spring. The drainage and pressure relief device includes the valve bonnet, diaphragm, gasket, drainage outlet, spring, and air block device.
