Disc check valves
The disc check valve consists of four main components: The body, a disc, a spring and a spring retainer. The disc moves in a plane at right angles to the flow of the fluid, resisted by the spring that is held in place by the retainer. The body is designed to act as an integral centring collar that facilitates installation. Where a 'zero leakage' seal is required, a soft seat can be included.
Advantages:
Used for a variety of fluids such as liquids, gases and vapors
Unique design which can be fitted into a wide variety of flanges
A spring assisted disc for reducing pressure drop and water hammer
Versatile
