The CRB-20 Series with worm gear actuation is engineered for medium to large diameter pipelines where robust manual control is required. Its double-flanged body design provides extra strength and is ideal for critical systems where mechanical integrity and alignment are important. The worm gear allows smooth, controlled opening and closing even under high pressure or flow conditions.
Designed for use in water distribution, desalination, power plants, and industrial processing, this valve offers durability, reliable sealing, and simple maintenance. The large handwheel ensures ergonomic operation, and the gearbox mechanism reduces operator effort, especially in larger sizes or when frequent actuation is needed.
