Product Overview

The ZD (R) SJ electronic electric angle regulating valve consists of a 3810L (or PSL series) straight stroke electronic electric actuator and an angle regulating valve body. It contains feeding and clothing functions, accepts unified 4-20mA or 1-5V · DC standard signals, converts current signals into corresponding linear displacements, automatically controls the opening of the regulating valve, and achieves continuous adjustment of process parameters such as pressure, flow rate, temperature, and liquid level of the fluid in the pipeline. The electronic electric angle regulating valve has the characteristics of sensitive action, simple connection, large flow rate, small volume, and high adjustment accuracy. The valve body is right angled, and the valve core is a single guide structure. The flow path of the valve body is simple and the resistance is low. Electronic electric angle regulating valves are particularly suitable for regulating high viscosity fluids containing suspended solids and granular media, which can avoid coking, bonding, and blockage.
