Manual Device
At WOGS, we supply robust manual devices designed for dependable, straightforward valve operation when automation isn’t required or when a manual override is needed. Our range of manual control devices—including worm gears, worm gear declutchable, and levers—provide safe, smooth, and precise manual control for a variety of valve types.
Manual devices are widely used in water and wastewater treatment, HVAC, oil and gas, marine, and general industrial systems, where simple, cost-effective valve operation is essential for day-to-day maintenance, emergency shutoff, or as a backup to automated systems.
What Is a Manual Device?
A manual device is a mechanical component used to open, close, or adjust a valve by hand, ensuring operators can maintain or control flow without the need for compressed air or electricity. They are valued for their reliability, ease of use, and low maintenance requirements.
Types of Manual Devices We Offer:
Worm Gears — Provide smooth, low-effort turning of larger valves with precise positioning and torque multiplication.
Worm Gear Declutchable — Allow seamless manual override of automated actuators, combining the benefits of motorized and manual operation.
Levers — Simple, direct hand levers for quick quarter-turn operation of smaller valves.
