Intelligent explosion-proof electric actuators control globe valve
A linear actuator opens and closes valves that can be operated via
linear force, the type sometimes called a "rising stem" valve.
These types of valves include globe valves, rising stem ball
valves, control valves and gate valves The two main types of linear
actuators are diaphragm and piston.
CHL series lineal electric actuator has the characteristics of
small volume , light weight, powerful function, integrated
intelligent setting and easy operation. The max stroke length is
1m, The max force is 250000N. Lineal actuator is widely used in
valve on/off and debug which is lineal motion
Shell--The shell is made of aluminum alloy, with anodic oxidation
treatment and polyester powder coating. It is strong
corrosion-resistant and enclosure IP67,NEMA 4 and 6, IP68 and
explosion-proof is optional.
Motor--Asynchronous motor, small, large torque, and small inertia
force, F-class insulation rating, with thermal protection to avoid
Manual Structure--The design of handwheel is safe, reliable,
labor-saving, small. Declutch to operate by handwheel if without
power, and reset automatically when power on. NOTE: when hadle in
manual operation, DO NOT change to electric actuator.
Indicator-- Installs indicator in the center axis and adopts convex
mirror design, no cumulate water, more convenient to observe.
Space heater-- It is used for controlling temperature to avoid
condensing internal of housing and keep dry.
Limit switch-- Mechanical, electronic double limit. Mechanical
limit stopper is adjustable, safe and reliable; electronic limit
switch is controlled by cam. Set position accurately and
conveniently, and not affected by excessive handle.
Torque Switch-- (Except CHQ-005/008/010) Providing overload
protection to avoid the damage of valve and electric actuator when
jammed by cutting power automatically.
Self-locking--Accurate worm and worm gear transfer large torque
efficiently , high efficiency, low noise (max. 50 dB), long life,
with self-locking, prevent inversion, as stable and reliable
transmission parts, no need to refuel.
Anti-off bolt—The bolt attaches to the shell and be not off when
remove the shell.
. Installation-- The installation size meets international standard
ISO5211 / DIN3337. If dirrerence, design in addition.
Circuit--Controlling circuit meets the single-phase or three-phase
power supply standard, circuit layout is reasonable and compact,
terminals meet various of additional functional requirements
The display of valve position—During the opening or closing
movement of actuator, the change of valve position on LCD is
displayed with large numbers.
Adjust the phase sequence automatically—Intelligent actuator check
and test the phase sequence for 3 phase power supply automatically,
users no need to consider about the phase sequence.
