Features & Benefits:
- Ductile iron housing, piston, and end caps provide long product life with durable, cost-effective operation.
- Output shaft made of high-strength alloy steel or 17-4PH stainless transmits torque without fatigue.
- Sintered bronze bushings or PTFE composite on the output shaft eliminate side loading of the 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.
- Heat-treated stainless steel thrust pins and rollers transfer piston force to 17-4PH stainless steel or ductile iron yoke by rolling to reduce friction. for longer life and more efficient torque transmission.
- PTFE 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 action.
- Bi-directional travel stops provide accurate valve rotation adjustment.
- ISO 5211 mounting pattern promotes easier valve adaptation by utilizing internationally recognized standards.
- Both series B and C have been certified to SIL 3 ratings.
- Actuators are rated IP66.
- The NAMUR drive slot on the output shaft enables accessory-driven components to maintain a compact assembly and eliminates the need for couplings.
- 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.
- An easily removable housing cover provides effortless access for internal inspection of the yoke mechanism.
