Weight & Lever Swing Check Valves

MGA Controls stocks a wide range of metal and resilient seat weight and lever swing check valves. These self-actuated, or automatic, non-return swing check valves are used to prevent the back flow of a liquid in a pipeline by using the forward flowing liquid to open the valve disc. This protects the pump from damaging surge pressure following pump shut down in a pumping station.

At MGA Controls, we have a wide selection of non-return swing check valves in a wide range of materials, meaning the components can be used in a wide range of applications and industries. Stainless steel swing check valves are a popular product, as the material makes them compatible with a wide range of media.

The optional weight and lever swing check valves assists in increasing the speed of closure, which helps to prevent or reduce the potential disc slam caused by surge and high reverse flow velocities.
