Valve stem sealing area: The most common leakage location is usually caused by aging or wear of the packing or sealing ring inside the packing box.

For high-pressure fluid applications (usually referring to medium and ultra-high pressure conditions, such as pressure ratings of PN ≥ 1.6MPa or higher).

Worm gearbox (worm gear reducer): Its core function is to reduce speed and increase torque, which is manually operated through a handwheel.

Function: Real time measurement of the actual temperature of the controlled medium (such as pipeline water temperature, room temperature.

In short, the core of bellows sealing is the use of flexible thin-walled metal tubes (bellows) that can expand and contract, completely and permanently isolating the valve stem from the process medium.
