■ Overview

The ZDLS electronic electric angle regulating valve consists of a 3810L (or PSL series) straight stroke electronic electric actuator and an angle valve. 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 angular valve has a small volume, light weight, and a top guide structure for the valve core, which has the characteristics of simple flow path, low resistance, and easy flushing.

Suitable for regulating media with high viscosity, suspended solids, and granular media that require right angle connections.
