Air actuated soft seated butterfly valve for on-off control of water 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 resistanceExtended life span of valve and seals with unique wave line seat and special disc shapeReduced torque from wave seal and disc design reduces size of actuator, lowering the costIncreased flow capacity with unique profile disc and two piece shaft designValves direct mount to actuator using standard ISO5211 international standards
