FT1 series dialing fork pneumatic actuators provide global customers with the latest in valve actuation design. It is a highly unique and reliable means of operating ball,butterfly or plug valves along with 90 degree rotating mechanisms.FT Series Pneumatic Actuators incorporate latest mechanical technology, materials available and our patented technology, through designing, developing, testing and engineering application, we have obtained a high grade product with the characteristics of reliability, high performance, long cycle life, large adjustment, highest levels of corrosion protection, wide selection of model with easy and economy.
• 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 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.
• Heat-treated stainless steel thrust pin 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 panern 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.
• NAMUR drive slot on 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 down time and providing a'man safe' spring.
• Easily removable housing cover provides effortless access for internal inspection of yoke mechanism.
