Gas-air non-return valve

The non-return valves shown here are used in heating systems as protection against backflow. These parts are made from a carbon filled PPS housing and a LSR silicone valve.

PPS is a non-deformable, ceramic-like material, which can withstand high temperatures. We also produce this valve in LSR for this same reason. It is compliant with EN 549 standards.
