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 FeaturesRugged 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 FeaturesExtended cycle life (1 million cycles) Rack & pinion design Highly visible valve position indicator Dry or lubricated pilot air Factory lubricated for normal life Anodized aluminum body with epoxy-polyester covers Namur & ISO mounting
