Check Valve

A check valve is a type of valve that allows fluids to flow in one direction but closes automatically to prevent flow in the opposite direction (backflow). Therefore, they are also revered to as non-return valves or one-way valves.

Control Seal is an experienced valve manufacturer who in the past has also created these valves. With our knowledge and experience, we are able to create a high quality non-slam check valve which can be used in the oil, gas and process industry.

They are commonly used in situations where stable operation is important or to protect equipment such as pumps, turbines or compressors. Check valves are necessary if there is a risk of condensate backflow. They are also applied in situations where it is critical to not have backflow, like the LNG process.
