HPA-G Heavy-duty Scotch Yoke Pneumatic Actuator

Description

HPA-G Series Heavy-duty Scotch Yoke Actuators are manufactured in many different combinations of sizes, cylinder diameters, and designs. Both the double acting (DA) or spring return (SR) designs are available installation on quarter turn valves such as ball, butterfly and plug valve

Scotch Yoke actuators are designed for use over a wide range of pressure or temperatures,A symmetric yoke provide more constant torque throughout - at both the break points and end positions.

Main Product Features

Weather proof design:allows the HPA-G Series Scotch Actuators to be suitable for installation both indoors and outside. They can be custom tted for both high and low temperature applications by changing the seals and lubricants to suit the application.

Self-lubricating and Wear resistance:Both the guide rod and piston rod are plated with hard chrome to provide a high level of wear resistance. HPA-G Series Actuators are permanently lubricated with materials and lubricants appropriate for the service conditions. No maintenance is required in normal service.

Corrosion Resistance:A three layer epoxy coating is applied to every HPA-G Series Heavy-duty Actuators in order to provide maximum protection against environmental corrosion
