Electric double-seat regulating valve is composed of DKZ type straight electric actuator and straight-through low-flow resistance double-seat valve, double-seat double-guided structure, the valve core is stable and reliable in the process of displacement, there are two valve seats and two plunger-shaped spools in the valve body, the fluid medium flows out through the upper and lower spool valve seats, with large flow, large allowable pressure difference, small unbalanced force, is a balanced structure double-seat valve, suitable for not very clean medium and leakage requirements are not strict occasions. It is widely used in the automatic adjustment and remote control of industrial production processes such as chemical, petroleum, metallurgy, power station, textile, papermaking and pharmaceutical.
