Air actuated soft seated butterfly valve for on-off control of hydrocarbons, oil and other media compatible with the materials of construction. Lug style valve sandwich mounts between standard ANSI /ASME B16.5 Class 125 / 150 flanges. Double acting actuators use an air pressure signal (80-120 PSI) to open and close the valve.

Butterfly Valve Standard Features
  • Rugged epoxy coated (3-layer) ductile iron body with stainless steel disc for maximum corrosion resistance
  • Extended life span of valve and seals with unique wave line seat and special disc shape
