Gas-air non-return valve
The non-return valve shown here is used in heating systems as protection against backflow. These parts are made from a PBT housing and a LSR silicone valve. PBT is a non-deformable, ceramic-like material, which can withstand high temperatures. We also produce this valve in LSR for this same reason. The LSR valve is mounted on the housing and as complete valve part supplied.
