Mechanism Characteristic Of DCL

MOTOR

Motor for the actuator is required to have high-start-up torque, so the actuator is capable to start up with full load whenever the valve is at the opening, closing and any intermediate positions. This is due to the working characteristic of valve. At the same time, the smaller rotation inertia is required for the motor due to the adjustment of the flow (opening range) . DCL series Electric Actuator is designed for such special requirement.

GEAR
It is made of the alloy steel, which is machined by CNC after heat treatment, featuring the high strength; good wear resistance and the long-term-fatigue load impact.
WORM & WORM WHEEL
Due to the working characteristic of valve, the output shaft for Actuator is required to operate under the conditions of long-time and high torque and the frequently changing the rotation direction. The traditional connection of key and pin between the requirement of the operating conditions. The problem has been thoroughly solved by the integral construction between the output shaft and worm wheel, which is adapted in DCL series Electric Actuator.
SCREW
Covers are tightened to the box body by the stainless steel screw. When dismantling the cover, the screw on the cover does not drop out in order to avoid missing.
LIMIT OF MECHANICAL STROKE
The stainless steel bolt and stopper for the limit of mechanical stroke can be used for exact adjustment of Actuator to a specific angle. For convenient adjustment, the bolt is located outside,and the stainless-steel nut can ensure it to be positioned after adjustment. The stroke termination is set to Angle 0-90°before ex-work.. However any angle can also be set.
VALVE POSITION DIAL
The starting angle of valve can be clearly indicated through the simple design. Indicates the full closing position of valve. Indicates the full open position of valve. The intermediate scale indicates the opening percentage of valve. The glass lens is stiffened with special treatment. The plastic lens, which is poor in performance for anti-aging and easily deformed by temperature, has been rejected.
BEARING /JOG SWITCH /CAPACITANCE
All the imported high-quality elements are the guarantee of long-term and stable operation of the Actuator.
