Product Brochure

• High pressure construction eliminates undesirable regulators and relief valves for supply pressures up to 1500 psig (103 bar).
• Hydraulic damping provides smooth 'open-close' operation to prevent detrimental valve slamming.
• Ductile iron housing, piston and end caps provide long product life with durable, cost effective operation.
• Cylinders provide unrivaled corrosion resistance.
• Output shaft made of high strength alloy steel transmits torque without fatigue.
• Sintered bronze bushings or sealed needle bearings on output shaft eliminate side loading of valve stem to maximize stem packing performance.
• Chrome-plated steel piston rod provides strength and corrosion resistance for enduring high cycle applications.
• Sintered bronze piston rod bushings provide low-friction support and precise alignment of the piston rod to increase efficiency, reduce maintenance, and extend actuator life.
• Teflon^® guide bands ensure low friction piston guidance during operation to protect cylinder walls from potential scoring and extend seal performance with a continuous cylinder wiping operation.
• Bi-directional travel stops provide accurate valve rotation adjustment.
• ISO 5211 mounting pattern promotes easier valve adaptation by utilizing internationally recognized mounting patterns.
• Drive slot on output shaft enables accessory-driven components to maintain a compact, low profile assembly.
• Tectyl-coated springs can be disarmed without special tools to safely and easily disassemble the actuator in the field, reducing downtime and providing a 'man-safe' spring.
• Removable housing cover provides effortless access for internal inspection.
