ZRP eccentric rotary valve ( CAM deflection control valve), consisted of the actuator and eccentric rotary valve, is a kind of angle trip control valve which composes with partly ball valve plate deflection, eccentric rod rotary to control building. Rotary center of valve disk not concentric with a rotary rod can reduce wear and prolong service life. Disk back set a contra-vane is an advantage for field stability flow and good stable. Secondly, large flow, adjustment scope wide and other features. It is used widely in petroleum, chemical, electric, metallurgy, steel, papermaking, medical, food, spinning, light industry, and other industry.
