手輪裝置

產品說明

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.

主要技術規格

• Mechanism: Worm Gear Reduction

• 操作： Multi-turn Handwheel

• Housing Material: Cast Iron / Painted Steel (Weatherproof)

• 相容性： ISO 5211 Mount Pads

• 功能： Self-locking (valve stays in position)

優勢與好處

• 安全： Prevents the handle from snapping back due to line pressure, protecting the operator.

• Ease of Use: Reduces the physical force needed to operate large valves by up to 80%.

• Water Hammer Prevention: The slow opening/closing speed prevents sudden pressure surges in the pipeline.

• Fine Adjustment: Allows for more precise positioning than a lever handle.

應用領域與位置

• Main Utility Lines: Large water or steam headers (4″ and above).

• High-Pressure Systems: Where line pressure makes lever operation impossible.

• Confined Spaces: Where there is no room to swing a long lever handle.
