ZDLJp Electronic single seat regulating valveDetailed product description：

The ZDLJp electronic electric precision small single seat regulating valve is composed of a 3610L series electronic electric actuator and a low flow resistance straight through single seat regulating mechanism. The electric actuator has a servo system inside and does not require a separate servo amplifier. It can be controlled by input signals and power supply. The connection is simple, and the valve body is a straight through single seat without a bottom cover guide structure. The valve core is a plunger type structure, which has the characteristics of small volume, light weight, large flow rate, and high adjustment accuracy. It is suitable for situations with high flow rate and strict leakage requirements.
