Product Name
Handwheel Device
Product Summary
Effortless Control for Large or High-Pressure Valves.
The Handwheel Device, also known as a Gear Operator, is designed to replace standard lever handles on larger ball valves. By utilizing a gear reduction mechanism, it allows operators to open and close heavy or high-torque valves with minimal physical effort. It ensures smooth, controlled operation, eliminating the “kick” often felt when operating large manual valves.
Product Description
As ball valves increase in size (typically above 4 inches) or pressure, the torque required to turn the ball becomes difficult for a human to manage with a simple lever. This device mounts to the valve stem and converts multiple turns of the handwheel into a slow, powerful 90-degree rotation of the ball. This mechanism is enclosed in a weather-resistant housing, making it suitable for outdoor use.
