The Wafer check valves are self-acting and fast-closing valves which prevent a working medium from flowing back in a pipeline. They are used in order to prevent from backflow the pumps, fans etc. TWafer check valve is not a shut-off valve.

Find a huge selection of Composite exhaust air valve from China at Milestone. Composite exhaust air valve is a barrel shaped valve body, which mainly contains a group of stainless steel balls, rods and plugs. Composite exhaust air valve is installed at the pump water outlet or in the water supply and distribution pipeline to remove a large amount of air accumulated in the pipeline, or a small amount of air accumulated at a higher place of the pipeline is discharged into the atmosphere, so as to improve the service efficiency of the pipeline and the pump Valve quickly inhales outside air to protect the pipeline from damage caused by negative pressure.

Cast steel gate valve is characterized by a “gate” that closes in a plane perpendicular to the flow of fluid. They are used primarily for on/off, nonthrottling service.

Quick exhaust valve is based on the buoyancy characteristics of water on stainless steel floating ball When the water level in valve rises, the floating ball will automatically float up under the buoyancy of water until it is connected with the sealing surface of the exhaust port. When the water level in valve decreases, the ball will drop with the water level. At this time, a large amount of air will be injected into the pipe through the exhaust port. After being installed on the pipe, the ball will automatically open / close the exhaust valve by using the inertia of water to the floating ball Air port.

The structure feature of the Center Line Butterfly Valve is that the stem axis, the center of the butterfly plate and the center of the body are in the same position.

Flanged Check Valve refers to the flow of the medium itself and automatically open and close the valve disc, used to prevent the medium flow back.
