ZD/RLJ electric angle control valve

Composed of 3810L series orPSL series (can also be configured with other or imported brand actuators) linear electronic actuator and angle adjustment valve body. The electric angle adjustment valve is equipped with an actuator that contains a feeding function, accepts a standard signal of 4-20mAor1-5V.DC, converts the current signal into a corresponding straight line displacement, and automatically controls the opening degree of the regulating valve. Continuous adjustment of process parameters such as pressure, flow, temperature, and liquid level in the pipeline.

The electric angle control valve has the characteristics of sensitive action, simple connection, large flow, small size and high adjustment accuracy. The

The electric angle regulator valve body is a right angle shape, the valve core is a single guide structure, the valve body flow path is simple, and the resistance is small.

Electric angle control valve is especially suitable for high viscosity, containing suspended solids and granular media fluid adjustment, to avoid coking, bonding, plugging.
