DELCO DKS Series Quarter Turn Electric Actuator, Fast 90° Rotation Precision Control, Compact Quarter Turn Electric Actuator for Industrial Valve On-Off & Modulating Control

DKS series electric actuators are used to control valves rotating from 0 to 90 degrees and other similar products, such as butterfly valves, butterfly valves, air doors, baffle valves, cock valves, shutter valves, etc., and can be widely used in petroleum, chemical, water treatment, ships, paper making, power plants, heating, light industry and other industries. It uses 380V/220V/110V AC power or 24V/110V DC power as driving power and takes 4 - 20mA current signal or 0 - 10V DC voltage signal as control signal to make the valve move to desired position and realize automatic control with a maximum torque of 2000N.

Performance Features

1. Shell - The shell is made of hard aluminium alloy with strong corrosion resistance after anodizing and polyester powder coating. The protection classes are IP67, NEMA4 and 6, IP68 and explosion - proof are available.
2. Electric machinery - Fully enclosed squirrel - cage motor, small size, large torque, small inertia force. Class F insulation with built - in overheat protection switch prevents motor damage.
3. Manual structure - The design of the handle ensures safety, reliability, labor saving and small size. When not energized, the wrench handle can be operated manually. Place the wrench in the wrench clip when not manual.
4. Indicator - The indicator is mounted on the central shaft to observe the valve position. The lens is designed as a convex lens without water accumulation and is easier to observe.
5. Space Heater - Used to control temperature, prevent condensation of moisture in actuator due to temperature and weather changes, and keep space electrical components dry.
6. Limit switch - Mechanical and electronic double limit. Adjustable mechanical limit screw, safe and reliable; The electronic limit switch is controlled by a cam mechanism and a simple adjustment mechanism allows precise and convenient positioning without battery support.(All microswitch contacts are silver)
7. Sealing - Good sealing, IP67 is the standard product protection level, and IP68 is optional protection level.
8. Self - locking - Precision twin - turbine worm mechanism can efficiently transmit large torque, has high efficiency, low noise (max. 50 dB) and long service life, with self - locking function to prevent reverse rotation, the transmission part is stable and reliable, and no further oil is needed in use.
9. Anti - drop bolt - When removing the housing, the bolts attach to the housing and do not fall off.
10. Install - Bottom mounting dimension conforms to ISO5211/DN337 international standard, double Quad bores facilitate linear or 45 degree angle mounting of valves with square rods, and are highly adaptable. It can be installed vertically or horizontally.
11. Circuitry - The control line conforms to single or three power supply standards, the line arrangement is compact and reasonable, and the terminal can effectively meet the requirements of various additional functions.
