Electric Bellow Seal Single Seat Control Valve

Product Description 

Electric bellow seal single seat control valve adopts top-guided unbalanced structure, high strength, heavy load, S-shaped flow path, small pressure drop loss, large flow coefficient, wide adjustable range and high flow characteristic accuracy. The valve cover is double sealed with bellows and packing, which fundamentally eliminates the possibility of medium leakage. This type of bellows-sealed single-seat Electric control valve is suitable for flow and pressure control of toxic or volatile media.

The electric bellow seal single seat control valve has a large adjustable range, the adjustable ratio of the control valve is 50, and the flow characteristics have linear and equal percentage characteristics. The valve body is designed according to the principle of fluid mechanics, and the flow channel of equal section and low flow resistance is designed, and the rated flow coefficient is increased by 30%. It adopts a soft sealing structure valve core, which reaches the VI level leakage standard, that is, zero leakage. The servo amplifier adopts deep dynamic negative feedback, which can improve the adjustment accuracy.
