Electric Flange Ball Valve (Type LQ)

The Electric Flange Ball Valve is a 90° rotary valve with excellent sealing, high flow capacity, and low flow resistance. Its simple structure ensures easy maintenance and long service life. The valve body's straight-through design matches the pipeline diameter, allowing minimal media loss. Equipped with LQ actuators, it is suitable for applications requiring strict sealing, including control of gases, liquids, steam, and media with fibrous impurities. Widely used in petroleum, chemical, metallurgical, light industry, papermaking, power plants, refrigeration, and other industries.

產(chǎn)品特點(diǎn)

? Low fluid resistance - Ball valves have minimal flow resistance, even reduced-bore types maintain low pressure drop
? Thrust bearings reduce stem torque for smooth long-term operation
? PTFE seat seals provide pressure-energized sealing (performance improves with medium pressure)
? Rotating stem design maintains packing integrity with pressure-enhanced sealing
? Self-lubricating PTFE materials minimize ball friction, extending service life
