V ball valve DN50, 100NM Electric Rotary Actuator
Rotary electric actuator is used for controlling 0°～360° rotation
of the valves and other similar products, such as butterfly valve,
ball valve, damper, flapper valves, cock valves, louver valve, etc.
It’s widely applied in petroleum, chemical, water treatment,
shipping, paper making, power plants, heating, light industry and
other industries. It is drived by 380V/220V/110V AC power. Control
signal is 4-20mA current signal or 0-10V DC voltage signal, which
enables the valve to move to the desired position, achieving its
automation. The maximum output torque is up to 6000N·m
Shell--The sheel is made of aluminium alloy, with anodic oxidation
treatment and polyester powder coating. It is strong
corrosion-resistang and enclosure IP67,NEMA 4 and 6, IP68 is
Motor--Fully enclosed squirrel-cage asynchronous motor, small,
large torque, and small inertia force, F-class insulation rating,
with termal protection to avoid damaging.
Manual Structure--The design of handle is
safe,reliable,labor-saving,small.If power failure, operted by
Indicator--Install indicator in the center shaft 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.
Sealing--Well sealing performance and enclosure IP67,IP68 is
Limit switch--Mechanical, electronic double limit. Mechanical limit
stopper are adjustable, safe and reliable; electronic limit switch
is controlled by cam, Set position accurately and conveniently, and
not affected by excessive handle.
Self=locking--Accurate worm and worm gear transfer large torque
efficiently, high efficiency, low noise (Max. 50dB), long life,
with self-locking, prevent inversion, as stable and reliable
transmission parts, no need to refuel.
Anti-offbolt--the bolt attached to the shell and be not off when
remove the shell.
Installation--The installation size meets international standard
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
