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

Butterfly Valve Standard Features
  • Rugged epoxy coated 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
  • Reduced torque from wave seal and disc design reduces size of actuator, lowering the cost
  • Increased flow capacity with unique profile disc and two piece shaft design
  • Valves direct mount to actuator using standard ISO5211 international standards

  • Pneumatic Actuator Standard Features
  • Extended cycle life (1 million cycles)
  • Rack & pinion design
  • Highly visible valve position indicator
  • Dry or lubricated pilot air
