The main differences between soft seal gate valves and hard seal gate valves are sealing materials, applicable working conditions, performance characteristics, and maintenance requirements.
Implementation standards: Based on national industry standards such as JB/T 8862, JB/T 8109, GB/T 24923, and GB 3836, covering the entire process of factory inspection, type testing, and on-site acceptance.
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.
