Description
ZDJW Electric Control and Shut-off Butterfly Valve
The ZDJW type electronic double-eccentric electric control butterfly valve is composed of an electronic actuator and a double-eccentric butterfly valve.

It uses a power supply of 220V·AC, 50Hz, and is equipped with a servo amplifier, a position signal generator, a handwheel mechanism, torque limit switches, travel switches, and a valve position indicator. It can accept 4-20mA·DC signals output by industrial control instruments or computers to control the valve opening, and can simultaneously output 4-20mA·DC valve position feedback signals. This butterfly valve features an advanced structure, convenient operation, reliable shut-off, and small leakage. The valve seat is available in both soft seal and hard seal types. It is suitable for occasions with large diameters and large flows. Due to its self-cleaning function, it is particularly suitable for regulating thick turbid slurries and media containing suspended particles.
