DINKONDA GLOBAL Power Plants Special GT Series Dual Piston Gear Tooth Strip Transmission Structure Angle Stroke Adjustment Pneumatic Actuator

Product Overview
The GT series regulating pneumatic actuator adopts a dual piston gear tooth strip transmission structure, which belongs to the angular stroke regulating drive device. It is equipped with an intelligent locator and receives 4-20mA analog control signals to achieve continuous opening adjustment of ball valves, butterfly valves, and plug valves, accurately controlling the flow rate, pressure, and temperature of the medium in the pipeline. Widely used in self-control pipeline systems that require continuous process regulation in chemical, water treatment, heating, oil and gas, environmental protection and dust removal industries.

Structural Composition
1. Aluminum alloy cylinder body
The cylinder barrel is made of extruded aluminum alloy profiles, with hard anodized inner walls, low friction coefficient, wear and corrosion resistance; Green aluminum alloy end caps at both ends, equipped with symmetrical double piston components inside. Through precision rack and pinion gear pairs, the linear motion of the piston is converted into a 90 ° angular stroke rotation of the output shaft, ensuring smooth transmission and stable output torque.

2. Gear and rack transmission mechanism
Double piston symmetrical layout, precise meshing of gears and racks, small clearance and low backlash; It is divided into two types: double acting and single acting (spring reset). The single acting model is equipped with a built-in spring component, which automatically resets to the preset safety position after the gas is cut off, meeting the requirements of process safety interlocking.

3. Intelligent valve locator
Equipped with an electrical valve locator, it receives 4-20mA analog signals from the control system, compares valve position feedback in real time, automatically adjusts cylinder intake volume, and achieves continuous adjustment of valve opening. It has valve position feedback and fault alarm functions, and can be paired with HART communication protocol (optional).

4. Top position indicator
The top integrated visual valve position indicator device intuitively displays the current opening status of the valve, facilitating on-site visual inspection. Limit switches can be installed to achieve full open and full close point signal feedback.

5. Standard installation base
The output flange complies with the ISO5211 international standard, with strong universality and can be directly matched with various angular stroke control valves; The cylinder body is reserved with a standard air source interface, which can be matched with an air filter pressure reducing valve to purify the air source.

Core Features
1. Continuous adjustment control, high positioning accuracy
Receive 4-20mA analog signal, achieve seamless adjustment from 0 to 90 °, high positioning accuracy, small hysteresis, stable control of medium flow, and meet the continuous adjustment conditions of the process.

2. Double piston gear rack structure, stable performance
Symmetrical piston with uniform force, smooth opening and closing action, and constant torque output; The cylinder body is treated with anodizing, which is wear-resistant and has a long service life. It supports double acting and single acting spring reset selection.

3. Optional spring reset to ensure safe working conditions
Single acting spring reset style, automatically returns to the preset safety position in the event of gas loss (gas loss on/off can be customized), suitable for process pipelines with safety interlock requirements.

4. Standardized interface, convenient accessory matching
ISO5211 standard connecting flange, suitable for various types of angular stroke valves; It can be equipped with air filter pressure reducing valve, solenoid valve, valve position transmitter, explosion-proof accessories, and the explosion-proof version is suitable for use in hazardous areas.

5. Easy maintenance and strong environmental adaptability
The sealing components come standard with NBR nitrile rubber and can be upgraded to FKM fluororubber, suitable for high temperature and weakly corrosive media; Protection level IP65, stable operation under outdoor and humid conditions.
