- Solid
thermoplastic body and bonnet for best overall corrosion resistance.
- Extra heavy EPDM diaphragm or optional PTFE
diaphragm fully backed by EPDM, for long service life under
the most severe conditions.
- Fully lubricated brass stem and sleeve.
- Unique concave/convex PTFE/ EPDM diaphragm
design insures PTFE barrier returns to full open position.
- Standard, adjustable full close position over
travel stop to eliminate premature diaphragm failure due to
overtightening.
- Full stroke, fully protected open/close position
indication.
- Stainless steel or plastic encapsulated external
hardware.
- Longer service life and higher Cv values than
rubber lined valves.
- Can be used in lined, metal FRP or thermoplastic
piping systems.
- Flanged application valves designed
to fit between ANSI B16.5 Class 150 flanges.
