Electric Diaphragm Control Valve Corrosion Resistance Fireproof

ZDLT Electric Diaphragm Control Valve

The ZDLT type electric diaphragm control valve consists of an electronic actuator and a diaphragm control valve. It is powered by a 220V AC power supply and receives a standard 4-20mA DC electrical signal to realize flow regulation and control of corrosive media such as strong acids and alkalis, as well as high-viscosity and harmful media in process pipelines. It is applied in corrosion-resistant systems such as petroleum, chemical industry, and metallurgy.

Product features: The valve has small flow resistance and large flow capacity, no stuffing box, no external leakage, and features corrosion resistance, fire resistance, poison resistance, safety and reliability. Good corrosion resistance can be obtained according to different linings and diaphragms.
