Product overview

Zdlp electronic electric single seat regulating valve is composed of 3810l (or PSL Series) straight stroke electric sub actuator and straight through single seat valve. It contains servo function, receives unified 4-20mA or 1-5V · DC standard signal, converts the current signal into corresponding linear displacement, and automatically controls the opening of the regulating valve to achieve continuous adjustment of process parameters such as pressure, flow, temperature and liquid level of fluid in the pipeline.

The single seat valve is suitable for occasions with strict requirements on leakage, low pressure difference before and after the valve, certain viscosity and a small amount of fiber medium. It is widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment and other industries
