RHA Type Variable Frequency Electric Valve Actuators High Torque 120v ODM

DINKONDA GLOBAL Power Plants Special RHA Type Intelligent Integrated 0~90 ° Angular Stroke High Torque Variable Frequency Electric Actuator

Product Overview
RHA type angular stroke electric actuator is an intelligent integrated angular stroke driving device, with a standard output of 0-90 ° angular displacement. It is specifically used to drive angular stroke valves such as butterfly valves, ball valves, plug valves, and air door baffles. The product integrates variable frequency drive assembly, intelligent servo controller, valve position detection unit, local operation panel, and manual emergency mechanism. It can receive DCS control system DC4-20mA analog adjustment signal or switch signal, realizing continuous adjustment or switch cut-off of valves. The product has a wide range of torque coverage, with characteristics of impact resistance and high reliability, and is widely used in industrial pipeline self-control systems such as thermal power generation, petrochemicals, metallurgy, municipal environmental protection, and heating.

Structural Composition
1. On site intelligent control unit
Integrated LCD display window and function operation knob, real-time display of valve position, operating status, and fault codes; Equipped with local/remote mode switching function, it can directly complete corner calibration and parameter configuration on site, making debugging and maintenance convenient. The panel is equipped with local control buttons that support on-site opening, closing, and stopping operations.

2. Motor and Variable Frequency Reduction Transmission Assembly
Specialized industrial motors paired with high-precision reduction gear mechanisms convert high-speed motor rotation into high torque 90 ° angular stroke output; The variable frequency version can achieve soft start stop, reduce opening and closing impact, and protect valves and transmission components.

3. Manual emergency operation mechanism
Equipped with a top hand cranked operating mechanism, the valve can be manually operated to open and close in case of power failure or control system malfunction, for equipment maintenance and emergency operation.

4. Valve position sensing feedback component
The high-precision angular displacement sensor real-time collects the valve angle position, outputs a DC4-20mA standard valve position feedback signal, and sends it back to the control system to form a closed-loop regulation loop, ensuring the accuracy of valve positioning control.

5. Multiple security protection modules
Built in torque protection, corner limit protection, and motor overheating protection. When the output torque exceeds the set threshold, the actuator automatically stops; The valve automatically limits when it reaches the fully open and fully closed positions to avoid overloading and damage to the valve.

6. High strength shell and independent wiring chamber
Die cast aluminum alloy shell, surface anti-corrosion spray coating; Independent sealed wiring chamber, explosion-proof model can be applied to flammable and explosive hazardous conditions, matched with cable sealing joints, safe and reliable wiring.

7. Output connection base flange
Standardized angular stroke output flange, can directly connect butterfly valve and ball valve stem, compatible with domestic and mainstream international valve connection standards.

Core Features
1. Angular stroke high torque output
0~90 ° angle output, multiple gear torque options, suitable for heavy-duty conditions such as large-diameter butterfly valves, ball valves, and flue baffles.

2. Variable frequency soft start stop, low impact load
Variable frequency speed regulation drive, adjustable opening and closing speed, smooth start and stop actions, reducing mechanical impact and extending the overall service life of valves and actuators.

3. Intelligent closed-loop regulation
Built in servo control algorithm, high positioning accuracy, customizable dead zone control, smooth operation, supports both switch type two position control and adjustable continuous flow and pressure regulation.

4. Local and remote dual-mode operation
Remote reception of control room signals; The on-site panel supports on-site operation and is equipped with a manual mechanism, making maintenance and debugging flexible and convenient.

5. Fault self diagnosis alarm
Real time monitoring of motor overheating, torque overload, angle exceeding, signal disconnection and other faults, with the display screen directly outputting fault codes for quick troubleshooting.

6. Excellent protective performance
Standard protection level IP65, dustproof and waterproof, suitable for outdoor, humid, and dusty industrial sites; Explosion proof version Exd Ⅱ BT4 meets the requirements for use in chemical explosion-proof areas.

7. Low operating vibration and high reliability
Precision gear transmission structure, with low overall vibration and noise, capable of long-term continuous and stable operation, suitable for continuous production process equipment.
