Product Description
The ZDLP type electronic electric single seat regulating valve is composed of the 381L and PSL series electronic electric actuator, along with the single seat regulating valve mechanism. The electric actuator is equipped with an internal servo system, eliminating the need for an additional servo amplifier. Simply connect the input signal and power to control operation, with easy connection. The regulating mechanism valve core features a top guidance design, suitable for applications with stringent leakage requirements, low pressure difference before and after the valve, and conditions with certain viscosity and containing fibrous media.
