ZDLP Cast Steel Electric Single-seat Regulating Valve
I. Product Introduction:
The ZDLP type cast steel electric single-seat control valve consists of a 3610L series electronic electric actuator and a single-seat regulating mechanism. The electric actuator has a built-in servo system, eliminating the need for an external servo amplifier. It can be controlled to operate with just an input signal and a power supply, featuring simple wiring. The valve core of the regulating mechanism adopts top-guiding design, making it suitable for occasions with strict leakage requirements, low pressure difference between the front and rear of the valve, and media with certain viscosity or containing fibrous substances. The electric single-seat control valve has the characteristics of high precision, large flow rate and small leakage, and is widely used in industrial automation control systems such as chemical industry, petroleum, light industry, power stations, metallurgy and other fields that require large flow rate and small leakage. The only difference between the ZDLP electric single-seat control valve and the ZAZP electric single-seat control valve lies in the actuator.
