Description

Electric socket regulating valve valve core structure is clearance fit, the sleeve and the disc has multiple throttling Windows on the sleeve, the shape of the window determines the flow characteristic of regulating valve, the area of the window size affect valve flow coefficient Cv. Since the seat is no thread card type structure, the cone sealing surface on the seat and disc on the cone sealing faces fitted to cut off the seal formation, ensure that the disc pressure on the valve seat when the valve tightly shut off. The size of the valve seat diameter affect valve flow coefficient Cv. Disc in parallel to the axial symmetry distribution balance hole, upper and lower end face of the valve chamber connected to this effect in the medium in the valve disc shaft lift most cancel each other out, unbalanced force produced by a dielectric on the valve stem is very small. Of industrial automation control system by receiving signals (such as: 4 ~ 20 ma, or 1-5 v DC) to drive the change between the cross-sectional area of the valve core and valve seat valve size control pipe medium of process parameters such as flow rate, temperature, pressure and etc. Automated regulating function.
