wafer type butterfly valve

API 609 triple eccentric butterfly valve, triple offset butterfly valve 2"-48"



Standard Features:


Kelite High Performance Butterfly Valve is from the family of quarter-turn valves. This valve is designed and manufactured to meet API 609 and ASME B16.34 specifications.


  • Sizes 2" to 48” are standard.
  • 150, 300 & 600 ASME Class ratings are standard.
  • Wafer, Lug, Flanged and Butt-Weld construction are available.
  • Flanged ends available from 4” and Butt-Weld ends available from 6”.
  • Pressure testing according to API 598.
  • Three types of seat designs are available, Non Fire Safe Seat, Fire Safe Seat and Metal Seat.
  • Soft seat valve designs are bidirectional.
  • Metal seat and Fire Safe seat designs are fire safe certified.
  • The valves have a center disc mounted to the vertical stem with disc pins.
  • When the stem rotates, the disc rotates around the vertical stem axis and closes or opens the valve.
  • The disc is mounted with double eccentric from the stem and valve axis.
  • This arrangement increase the life of the seat.
  • The stem is a blowout proof design which prevents the stem from blowing out in case of stem breakage.
  • The seat has a spherical seating surface , which reduces the torque required
  • The seat is retained by the seat retainer, which prevents the seat from blowing out during operation.
  • The seat can be changed between soft seat, metal seat and fire safe seat with same seat retainer bolted to body.
  • Gear operator can be mounted on the valve with a mounting bracket.
  • Tight shutoff leakage class VI possible with Soft seated(Non Fire Safe) and Fire Safe soft seated valve designs.
  • Leakage class V is applicable to metal seated valve designs.


Design characteristics :


  • Compact structure, easy installation and disassembly, repair friendly and light weight.
  • It has a certain adjustment capability, and can be used as a control valve.
  • With the triple-eccentric structural design, the sealing face is separated as soon as opening, so the mechanical wearing and friction between two sealing faces is eliminated during the opening and closing of butterfly plate, the operation torque is lowered, and the service life is longer.
  • Good sealing performance of zero leakage.
  • Wide range of application - triple-eccentric metallic sealing butterfly valves have a wide range of temperature, pressure and diameter.
