Notes

WRAS approved material for drinking water upon request.
The check valve is generally suitable for cleaning media, and should not be used for media with solid particles and high viscosity.

Description

A swing check valve utilising an angled seat and a fully encapsulated, resilient rubber flap disc to prevent reverse flow automatically. The disc assembly comprises a steel plate and steel rod substrate reinforced with nylon cloth and covered with rubber, rated for up to 1 million operating cycles. Suitable for horizontal installation in water supply, drainage, and pump-discharge applications.
