Flap Valves
KWT flap valves are available in a number of styles and can be fitted in a number of ways making them very flexible in terms of application. As well as a flexible range of standard designs we can also develop and manufacture bespoke flap valves to suit unique and special requirements.
Flap valves are a very traditional method of preventing back flow in pipelines, culverts and other applications to prevent flooding. The KWT models are manufactured using modern materials and the latest manufacturing techniques to ensure the very best products are achieved in the most efficient manner. Due to the unique lightweight properties of the HDPE that is used to manufacture the flap valves, they are very easy to install in comparison to cast iron flap valves
