ZDLP electric single-seat control valve is composed of a straight-stroke electric actuator and a small single-seat valve. Contains the function of feeding clothes, accepts a unified 4-20mA or 1-5V (DC) standard signal, converts the current signal into the corresponding linear displacement, and automatically controls the opening of the regulating valve to achieve the pressure and flow of the fluid in the pipeline Continuous adjustment of process parameters such as temperature and temperature. It is suitable for occasions with strict requirements on leakage, small pressure difference before and after valve, certain viscosity and a small amount of fiber medium.
