DINKONDA GLOBAL Power Plants Special Heavy Duty Angular Stroke Drive With Manual Hydraulic Pump, Fork Type Variable Torque Transmission Pneumatic Actuator

Product Overview
Equipped with a manual hydraulic pump, fork type pneumatic actuator, ultra heavy duty angular stroke drive device, adopting a fork to torque transmission structure, integrating an independent manual hydraulic operation unit, using clean compressed air as the main power source, outputting 0-90 ° angular stroke, specially matched with heavy-duty angular stroke valves such as ball valves, butterfly valves, plug valves, etc. with large caliber and ultra-high pressure difference. The single acting model is equipped with a built-in spring energy storage cylinder, which can drive the valve to automatically reset when the gas source loses pressure; Equipped with a manual hydraulic pump system, it relies on hydraulic power to achieve valve opening and closing in case of gas outage or emergency fault conditions, meeting the requirements of high safety level process interlocking. It is widely used in strict industrial pipeline self-control systems such as long-distance gas, oil and gas storage and transportation, large-scale petrochemical, thermal power, etc.

Structural Composition
1. Main cylinder assembly
High strength cast steel cylinder body, multi pull rod fastening structure, high pressure rating, precision honing of inner wall, low friction resistance; The whole machine is coated with red heavy-duty anti-corrosion coating, which is resistant to atmospheric corrosion. Single acting configuration of spring energy storage cylinder, achieving a fault safe position (fault on/fault off) in case of gas source failure.

2. Forklift transmission box
Thick cast steel integrated box with strong rigidity and resistance to impact loads. Internal shift fork transmission pair converts piston linear motion into output shaft rotational motion; The fork and pin shaft have undergone quenching and tempering heat treatment, which is fatigue resistant and can withstand the huge starting torque of high-pressure differential valves. A valve position output square head is installed at the top of the box for the installation of valve position feedback accessories.

3. Manual hydraulic emergency unit
Integrated manual hydraulic pump station, including operating handle, pressure gauge, hydraulic control valve group, and hydraulic oil tank. In emergency situations without a gas source, manually pulling the handle generates hydraulic pressure to drive the actuator to complete the valve opening and closing action; The pressure gauge displays hydraulic pressure in real-time for easy operation and monitoring, serving as a safe backup drive for pneumatic failure.

4. Adjustable mechanical limit component
External limit adjustment bolts are installed on both sides of the box, which can be used to fine tune the fully open and fully closed positions within a range of 0~90 ° without disassembling the entire machine. The on-site debugging is convenient and prevents damage to the valve body and internal components of the actuator due to overtravel.

5. Output flange and accessory interface
The output flange complies with the ISO5211 international standard and can be directly connected to various large-diameter angular stroke valves, with strong versatility. The box is reserved with standardized installation interfaces, which can be equipped with accessories such as solenoid valves, air filtration pressure reducing valves, valve positioners, valve position feedback devices, etc., to achieve switch control or continuous adjustment of DC4-20mA.

Core Features
1. Fork to fork torque conversion, ultra large heavy-duty output
The fork transmission structure ensures that the torque reaches its peak when the valve is opened and closed, and is specially adapted for working conditions with large diameters and high pressure differentials. Its heavy-duty performance is far superior to conventional gear rack actuators.

2. Gas liquid dual drive, high safety redundancy
Pneumatic action is the main drive, and manual hydraulic pump is used as an independent emergency drive; When the gas source is interrupted or the pneumatic components fail, the hydraulic system can be relied on to open and close the valves, meeting the safety redundancy design of high-risk processes.

3. Two types of action are available for selection
Double acting: relying on gas source pressure to achieve valve opening and closing; Single acting spring reset: automatically reset to the preset safe position upon loss of air, adapted to the requirements of fault on/off process.

4. High strength impact resistant structure
Cast steel box body+multi pull rod cylinder structure, with high overall strength, resistance to vibration and pressure impact; Red heavy-duty anti-corrosion coating, suitable for outdoor, humid, and corrosive atmospheric environments.

5. Adjustable itinerary on-site
External mechanical limit screw, no need to disassemble, can directly adjust the fully open and fully closed angle of the valve on site, with high precision in positioning.

6. Explosion proof configuration is optional
It can be equipped with explosion-proof solenoid valves and explosion-proof valve positioners, with a maximum explosion-proof rating of Exd Ⅱ CT6, suitable for flammable and explosive hazardous areas.
