ZL Series(Explosion Proof Version)

Overview

ZL series multi-turn valve electric actuator is an improved and perfected structure based on the original mature products, with optimized protection performance and key components. It is a driving device that realizes intelligent opening, closing and regulating control of valves. This series of actuators has the characteristics of full functions, reliable performance, advanced control system, small size, lightweight, easy use and maintenance, etc.
ZL series actuators are suitable for valves with linear motion of opening and closing parts, such as gate valves, stop valves, diaphragm valves, plunger valves, intercept valves, sluice gates, etc. They can be used for rising stem valves and concealed stem valves. When matched with turbine boxes, they can be used for ball valves, butterfly valves and dampers, etc. They can perform local control, remote control and automatic control on valves, and are widely used in industries such as electricity, metallurgy, petroleum, chemical industry, pharmaceuticals, water services, and agricultural irrigation.

(8) Main functional features of intelligent electric actuators
Mechatronic design, small size, and lightweight
It adopts a digital integrated chip, with powerful functions and high precision.
With a non-intrusive design, parameter setting and debugging can be done through knobs or infrared remote control without opening the box cover. The operation is simple and fast, and the sealing is higher.
The stroke displacement adopts an absolute encoder, the valve position will not be lost, the anti-interference ability is strong, the accuracy is higher, and the service life is long.
The LCD subtitles are available in Chinese or English.
It has functions such as travel limit protection, torque protection, stall alarm, overheat protection, signal failure protection, power phase loss protection, and automatic phase sequence identification and correction.
Intelligent types include intelligent switch type, intelligent adjustment type, and advanced intelligent type.
