Worm Gear Operated Ball Valve

The worm gear operated ball valve is engineered for reliable performance in large-diameter, high-pressure piping systems. Its worm gear mechanism multiplies manual input force, significantly reducing the effort required to open or close the valve. This makes the worm gear operated ball valve particularly suitable for oil & gas pipelines, chemical plant networks, municipal water supply systems, and thermal power stations. It effectively controls crude oil, natural gas, industrial wastewater, and high-temperature steam, providing stable shut-off and smooth operation that meets the demands of large-scale fluid systems.

Constructed from high-strength cast steel or stainless steel, the body of this is precision-cast with uniform wall thickness to withstand high-pressure impact. The worm gear and gear wheel are manufactured from ductile iron or alloy steel, heat-treated and machined to ensure smooth engagement and low wear. The ball is fully forged and polished, and is paired with PTFE soft seals or metal seats for dependable, leak-free sealing.
Production follows GB/T 12237 and API 6D standards, with each valve tested for hydrostatic pressure, seat tightness, and transmission efficiency, guaranteeing reliable performance under demanding conditions.

The core advantage of this worm gear operated ball valve is its effortless operation-requiring over 60% less torque than standard manual valves. The gear-driven mechanism ensures smooth, precise positioning without sticking. An integrated locking device prevents accidental operation, enhancing overall system safety. Flanged connections allow easy installation across a wide range of pipe sizes.
With a simple structure and highly interchangeable wear parts, maintenance is straightforward and cost-effective. Whether for standard applications or challenging high-pressure, large-bore scenarios, the delivers dependable shut-off performance and long-term value.
