Comosite Durcor-62™ valve body is light weight, provide maximum external corrosion protection, tensile and impact resistance. PTFE seat is .125" nominal thickness and is recessed into body, seat is energized by one piece non-wetted elastomer providing bubble tight sealing. Once piece 316 s.s. disc & Stem provides high Cv valve. blow-out protection and has double "D" shaft drive, can be lined with PFA / UHMWPE or unlined. Mounting Flange is ISO 5211 compliant. NPT connections (optional) for purge or leak detection, inert gas pad or sealing lubrication port. PTFE composite bearing (top & bottom) is self-lubricating, reduces friction and is maintenance free.

Triple stem seals top and bottom. 304 s.s. coil springs keep preload on stem seal and taper ring. 304 s.s. tapered rign compresses energized PTFE liner onto locking barbs, creates toruous no leak path. Locking barbs molded or machined onto disc stem. Stem seal is created through an interference fit as the stem is passed through the body liner. Primary seal is achieved at the disc hub and liner (ball & socket) through preloaded force.

Bottom heavy hex fasteners eliminates exposure to leaks from overhead equipment, PTFE coated B7 standard. Other materials available. Flanged Wafer or Lug design with composite threads 250ft. pound pull - out strength. Alloy inserts also available.
