Non Return Valve Types
Features & Benefits of Non Return Valve Types
Features
The structure is ideal both in terms of flow and process requirements. In addition, turbulence does not occur during emptying
It can provide all the current international standard interfaces, such as welding type, clamp type or thread type.
The non return valve body materials are all US304.SUS316L. Of course, other alloy steels can also be used according to customer requirements.
Bottom valve can be equipped with manual or pneumatic. A foot valve must be installed for each water pump.
The foot valve is usually installed below the water surface, while the water bottom valve is installed above the water surface. ,
Is an ideal water diversion equipment and can also replace the vacuum pump and vacuum device.
The surface of the valve body can be mechanically polished or electropolished according to customer requirements, and the accuracy can reach 0.25um.

Select and Use
In order to prevent reverse flow of medium, Non return valve shall be installed on equipment, device and pipeline
Non return valve is generally suitable for cleaning medium, not suitable for medium with solid particles and high viscosity
The installation position of swing check valve is not limited. It can be installed on horizontal, vertical or inclined pipelines. If it is installed on vertical pipelines, the flow direction of medium shall be from bottom to top
For high and medium pressure check valves with DN greater than 50mm and less than 600mm, swing check valve should be selected
