1 – Glass fiber reinforced polypropylene plastic valve body
2 – Polished aluminum ceramic valve plate
3 – Carbon-filled PTFE slide valve
4 – UHMW polyethylene valve carrier with permanently lubricated seals
5 - Low friction carbon filled PTFE slide valve on the polished alumina ceramic valve plate allows for longest life and superior sealing eliminating air leakage. It also eliminates high cost seals moving over holes, as needed on many competitors’ valves.
