Available in both worm and bevel gear configuration for butterfly, gate and globe valves, Acro-Gears dual input manual valve operators are particularly effective for use on valves with a high seating/ unseating torque, resulting in reduced effort in this operation while maintaining a lower number of turns in the middle portion of the valve’s travel where lower operating torque is required.
Acro-Gears dual input manual valve operators utilise a secondary input, which provides additional mechanical advantage of up to 5 times the primary ratio, making them ideal for unseating sticky valves that have not been operated for a period of time. After unseating the valve, the operator can simply elect to use the primary input, which provides a lower ratio for faster operation and lower number of turns.
Key features of Acro-Gears dual input manual valve operators:
- Heavy duty ductile iron castings
- Heat treated machine-cut gearing
- Standard IP67 O-ring sealed enclosure suitable for temporary submersion
- IP68 and buried service options also available on request
