1/4 Turn Vane Actuators

Comprise the simplest and most reliable mechanism for quarter-turn rotary actuation in the operation or positioning of ball, butterfly and plug valves.

• Single moving part - Simplest and most reliable mechanism for quarter-turn rotary actuation.
• Close couple control modules - Fail-safe spring returns, limit switches, positioners and solenoid valves all close couple to the actuators.
• No cranks or gearing - No power loss or backlash - allows accurate positioning.
• Durable corrosion resistant finish - Long maintenance-free life Up to 4 million operations guaranteed.
• Compact - space saving – efficient - Best torque/size package available, fast operating speeds, best air consumption, proven design.
• Millions of units in trouble free service all over the world
• Choice of male or female output drive square - easy to interface to application
• Unique serial number for identification and traceability
