Ball valve stems are critical components that connect the handle or actuator to the ball inside a valve, transmitting rotational motion to open or close the flow path. As a key part of the valve assembly, the stem must withstand torsional stress, pressure, and corrosive media while maintaining precise alignment and leak-free operation.
The company manufactures high-precision ball valve stems for use in industrial flow control systems, including oil and gas, chemical processing, and power generation applications. Machined on advanced CNC lathes and multi-axis turning centers, our valve stems deliver tight tolerances, excellent surface finish, and long-term reliability under demanding operating conditions.
Size Range: From miniature Ø4mm x 10mm to large Ø300mm x 2000mm, accommodating a wide variety of valve designs and pressure classes.
