The ZDLP electronic electric single-seat control valve is composed of the 3810L type (or PSL series) linear electric sub-motor actuator and a straight-through single-seat valve. It incorporates servo functionality and accepts unified 4-20mA or 1-5V·DC standard signals. These signals are converted into corresponding linear displacements, automatically controlling the opening degree of the control valve to achieve continuous regulation of process parameters such as pressure, flow, temperature, and liquid level in the pipeline.
Single-seat valves are suitable for applications where leakage is strictly controlled, where the pressure difference before and after the valve is low, and where the medium has a certain viscosity and contains a small amount of fibers. They are widely used in industries such as power, metallurgy, chemical engineering, petroleum, environmental protection, light industry, and equipment.
