TEFLINE-P PTFE LINED CPVC LUG BUTTERFLY VALVE

OVERVIEW: Stayflow Tefline-P Series PTFE Lined High Performance Butterfly Valves are custom manufactured in sizes 2" to 6". This advanced technology TFM Lined CPVC valve is specially designed for applications requiring high purity and maximum chemical resistance. The seal fully isolates process media to disc and liner contact only.

Direct disc-to-liner seal between ECTFE fluoropolymer disc and TFM liner for positive shut-off.

• Specially designed offset disc lifts quickly from sealing surface to minimize wear and reduce operating torque.
• Special disc-to-liner interface isolates valve components from process media. Eliminates stem and elastomer backing seal contact with process fluids. In the unlikely event of seal failure, leakage is expelled externally to protect process integrity. TFM skirt is integrally formed as part of the liner to isolate the CPVC body.
• Solid, fully isolated type 316 stainless steel stem is additionally PTFE coated as a safeguard.
• Lug style, chemical and corrosion resistant CPVC body features integrally molded actuation mounting pad and provides increased temperature handling capability to 200°F.
• 316 stainless steel Lug Inserts provide quick single-side valve installation and easy system add-on.
• Low Profile Gear Operator features high efficiency worm gear drive with built-in position indicator and high impact polypropylene handwheel. Operator housing is powder coated for improved cleanliness. Reversible for either right or left side operation.
• 150 psi Maximum Internal Pressure rating at 73°F.
• All  are constructed from CPVC Type IV Cell Classification 23447 with TFM liner and ECTFE disc.

Pressure Rating @ 73°F (23°C), Water 2" - 6". 150 psi Maximum Service Temperature 200°F (93°C).

A metal body butterfly valve with a PTFE lining is also available with our Tefline-M Series.

Suitable for Oil-Free air handling to 25 psi, not for distribution of compressed air or gas.
