The American Standard Bevel Gear Globe Valve is a globe valve designed and manufactured according to American standards, operated by a bevel gear transmission mechanism. Its most significant feature is the use of a bevel gear device to convert the rotational motion of the handwheel into the linear up-and-down movement of the valve stem, thereby achieving valve opening or closing. This transmission method greatly reduces the torque required for operation, making it easy and effortless to operate even large-diameter or high-pressure globe valves, especially suitable for heavy-duty valves requiring frequent opening/closing or remote control. This valve is widely used in industries such as petroleum, chemical, pharmaceutical, fertilizer, and power generation for on/off service of pipeline media.
