Heavy Duty Pneumatic Valve Actuators Double Acting ISO5211 Standard 10Nm-5000 Nm

DINKONDA GLOBAL Power Plants Special Fork Type Double Acting Heavy-duty Pneumatic Valve Actuators With External Air Storage Buffer Structure

Product Overview
This is a fork type heavy-duty pneumatic actuator with an external air storage buffer structure, which belongs to the special valve drive device for power stations. The equipment is equipped with independent gas storage buffer components, a complete set of gas source processing units, solenoid valves, and valve position feedback components; Relying on external gas storage tanks to achieve gas loss buffering and stable opening and closing, mainly equipped with flue damper doors, process butterfly valves, and air duct dampers in thermal power plants, suitable for automatic control conditions with large fluctuations in gas source pressure and the need for buffering and pressure stabilization.

Structural Composition
1. Main drive cylinder
Aluminum alloy cylinder barrel, hard anodized surface, multiple stainless steel tie rods to lock the cylinder head, reserved lifting lugs on the side of the cylinder body for easy on-site installation and handling, lightweight and wear-resistant overall structure.

2. Fork type transmission box
The internal roller fork transmission structure of the box, with amplified torque at the end of valve opening and closing, can overcome the valve body jamming caused by dust accumulation and high-temperature media; Install a visual valve position indicator above the box to provide real-time feedback on the valve switch status.

3. External gas storage cache assembly
External air storage buffer chamber paired with metal high-temperature resistant hose for storing compressed air; When the gas source suddenly loses pressure, the buffer gas can support the valve to complete a safe reset or short-term hold, avoiding the impact caused by the sudden action of the pipeline valve.

4. Integrated gas source control module
Integrated two position five way solenoid valve, explosion-proof limit switch, air filter, pressure regulating valve, and stainless steel connecting pipeline. The entire set of pneumatic components has been pre installed and can be put into operation on site by simply connecting to the main gas source.

5. Standard installation base flange
The actuator base follows the ISO5211 universal flange standard and can be adapted to most angular stroke valves such as butterfly valves, ball valves, smoke dampers, and air duct dampers.

Product Features
1. External gas storage cache voltage stabilization
Independent gas storage structure, buffering gas source pressure fluctuations; Maintaining power output under unstable gas supply and instantaneous pressure drop conditions, ensuring smooth valve operation, and suitable for on-site environments with fluctuating air sources for power plant air compressors.

2. Dual action driving mode
The dual chambers of the cylinder control the opening and closing of valves separately; Cooperate with the gas storage buffer structure to achieve gas loss buffering and position protection, preventing sudden valve opening and closing from impacting the pipeline.

3. Fork amplification output
The torque at the end of the stroke is doubled, and the overload output capability is excellent. It can drive large-diameter desulfurization and denitrification flue butterfly valves and induced draft fan baffle doors.

4. Complete set of accessories integrated pre installed
Filter, pressure reducing, solenoid valve, position switch complete assembly, stainless steel high-temperature resistant hose resistant to high-temperature flue gas baking, suitable for high temperature environment around the flue.

5. Strong adaptability to working conditions
Aluminum alloy cylinder body is corrosion-resistant and lightweight; The layout of gas circuit components is well-organized, which facilitates later maintenance and debugging of gas supply pressure.

6. Rich functional expansion
Manual emergency mechanisms, intelligent valve positioners, valve position transmitters, and explosion-proof casing components can be installed.

Application
1. Thermal power generation industry: boiler desulfurization and denitrification flue butterfly valve, induced draft fan supply fan baffle door, hot air duct valve, circulating water pipeline shut-off valve;

2. Petrochemical industry: smoke ventilation dampers, heavy-duty automatic control valves for high-temperature process pipelines;

3. Metallurgical, municipal heating, sewage treatment large ventilation baffles, water supply and drainage butterfly valves;

4. Priority is given to critical process pipelines that require gas storage buffering and smooth opening and closing due to unstable gas source pressure.

Installation Instructions
Use the cylinder body lifting ears to complete the lifting, and tighten the bottom flange and valve bolts; The main air source is connected to the right air source triad, and the cylinder is controlled to rotate back and forth through an electromagnetic valve; The external air storage buffer unit is pre filled with compressed air to cope with pressure fluctuations in the air source and ensure stable valve operation.
