1、 Introduction to ZARP Electric Eccentric Rotary Valve
ZARP ElectricEccentric rotary valveThe cam deflection regulating valve consists of an actuator and an eccentric rotary valve, and is a type of valve that controls fluid by rotating a portion of the ball valve plate around an eccentric axisAngular stroke valveThe rotation center of the valve core is not concentric with the rotation axis, which can reduce wear and prolong service life. There is a guide wing at the rear of the valve core, which is conducive to stable fluid flow and has good stability. Secondly, there are also characteristics such as high traffic and wide adjustable range. Widely used in industries such as petroleum, chemical, power, metallurgy, steel, papermaking, pharmaceuticals, food, textiles, and light industry.
