Bevel Gear Operated Rising Stem Gate Valve
Product Introduction
This valve combines a rugged cast steel body with rising stem design and precision bevel gear mechanism, engineered for large-diameter, high-pressure applications. The externally threaded stem provides visual position indication, while the gearbox multiplies handwheel force 3-5 times for effortless operation of valves up to DN1200. Hardened sealing surfaces ensure durability in petroleum, chemical, and power industries.
