ZDLP electric single-seat regulating valve

Features and applications

ZDLP type electronic electric single-seat regulating valve is composed of 3610L series electronic electric actuator and single-seat regulating mechanism produced jointly with KOSO company of Japan. There is a servo system in the electric actuator, no need to configure a servo amplifier, there is an input signal and power supply to control the operation, the connection is simple, the valve spool of the regulating mechanism is guided by the top, which is suitable for the occasion of strict leakage requirements, low pressure difference before and after the valve and a certain viscosity and containing fibrous media.
