DINKONDA GLOBAL Power Plants Special Double Acting AT Type And Single Acting SR Spring Reset Type Series Angular Stroke Pneumatic Drive Intelligent Adjustment Pneumatic Actuator

DINKONDA GLOBAL Power Plants Special Double Acting AT Type And Single Acting SR Spring Reset Type Series Angular Stroke Pneumatic Drive Intelligent Adjustment Pneumatic Actuator

Product Overview

The AT/SR series intelligent adjustable pneumatic actuator is an angular stroke pneumatic drive device, which is divided into two categories: double acting AT type and single acting SR spring reset type. The product is equipped with an intelligent valve locator and an air filter pressure reducing valve. It receives a 4-20mA analog control signal from the central control and outputs a 0-90 ° angular stroke. It accurately drives regulating valves such as ball valves, butterfly valves, and plug valves to continuously adjust the flow rate, pressure, and liquid level of the medium in the pipeline. It is suitable for industrial automation continuous control scenarios and widely used in processes such as thermal power, chemical engineering, and water treatment.

Structural Composition

1. * * AT/SR cylinder body**
The cylinder body is made of aluminum alloy extrusion molding, and the inner wall is hard anodized for wear resistance and corrosion resistance. AT is a dual piston dual action structure; SR has a built-in reset spring that automatically resets to a safe position when the gas is cut off. Gear rack transmission converts air pressure into rotational torque, with gray dust-proof end caps on both ends and sealed with fluororubber sealing rings.

2. * * Air filter pressure reducing valve (air source component)**
Integrated pressure gauge filters and removes water from compressed air, stabilizes gas supply pressure, and provides a clean and constant pressure gas source for the locator and cylinder, avoiding impurities from damaging precision components.

3. * * Intelligent valve positioner**
The entire set of adjustment control core receives 4-20mA control signals from DCS/PLC, compares the actual feedback of valve position, dynamically adjusts the cylinder intake volume, automatically corrects the valve opening, and achieves high-precision continuous adjustment; Equipped with valve position detection and fault diagnosis function.

4. * * Mechanical connection bracket and gas pipeline fittings**
The locator is linked to the actuator output shaft through the installation bracket, and the stainless steel joint and PU hose complete the pneumatic transmission; The bottom adopts ISO5211 international standard flange, which can be directly connected to various angular stroke control valves.

Core Features

1. * * High precision continuous adjustment**
The intelligent locator has closed-loop control, high adjustment accuracy, fast response speed, and can achieve valve opening positioning at any degree according to control signals, meeting the continuous adjustment requirements of the process, which is different from ordinary switch type pneumatic actuators.

2. * * Two operating condition versions are available for selection**
AT double acting type: high output torque, suitable for large-diameter valves, and the valve remains in place when the air source is lost;
SR spring reset type: Automatic reset upon loss of air (fully open/fully closed, optional), used for process circuits that require fault safety protection.

3. * * Gas source purification and protection design**
Equipped with a filter pressure reducing valve, it removes moisture and dust from the compressed air, stabilizes the gas supply pressure, protects the precision throttling components of the locator, and extends the service life of the entire equipment.

4. * * Rich diagnostic and feedback capabilities**
The intelligent locator can upload valve position feedback signals of 4~20mA, and some versions support HART communication. It can remotely read valve status, pressure, and fault alarm information, making it easy for equipment predictive maintenance.

5. Durable and reliable, with strong environmental adaptability

Aluminum alloy cylinder body is lightweight, and the anodized layer is wear-resistant; Fluororubber seals are resistant to oil and medium corrosion, and special sealing materials can be selected for high and low temperature conditions; Explosion proof models are available, suitable for flammable and explosive chemical scenarios.

6. Standardized Universal Interface

The output flange and shaft sleeve of the actuator follow the ISO5211 standard, and butterfly valves and ball valves can be matched, making on-site installation and replacement convenient and reducing project spare parts management costs.
