FR series pneumatic eccentric rotary valve and valve cam flexure, the plum kneeland technology, the single seat valve, ball valve, butterfly valve and other advantages, has the advantages of simple structure, small volume, light weight, rated flow coefficient, large adjustable range, wide temperature range, a small amount of leakage, prominent advantages good stability. Because the valve core, valve rod only rotate, so in the work process of the friction small, close the ball valve actuator thrust and requirements of the valve, butterfly small compared to. The products are widely used in chemical, metallurgical, power plants and other industrial process automatic control system.
