What Is a Check Valve?
Yuanda Check valves are usually installed in the pipeline to prevent backflow. A check valve is basically a one-way valve in which the flow can flow freely in one direction, but if the flow turns, the valve will be closed to protect the piping, other valves, pumps, etc. If the flow is diverted without a check valve installed, a water hammer may occur. Water hammer often occurs with extreme force and can easily damage pipes or components.
Technical Requirement:
1. Flange End: BS EN1092-2;
2 Test: ISO5208；

Where are the check valves used?
Check valves can be used in many different applications. For example, they are usually placed on the outlet side of the pump to protect the pump from backflow. The centrifugal pump is the most common type of water pump. It is not self-priming, so a check valve is essential to keep the water in the pipeline. In addition, check valves are often used in HVAC systems (heating, ventilation, and air conditioning systems). For example, HVAC systems are used in large buildings, where the coolant is pumped many storeys up. The check valve is installed here to make sure that the coolant will not be flushed back.
All check valves are suitable for various applications such as gas and liquid pipelines, water and steam systems, cooling towers, water treatment, gas export facilities, product tank farms, gas storage, and Mining dehydration.
