Industrial Pneumatic Actuators

Zhejiang Bigtork Valve Automation Co., Ltd. is one of the leading manufacturers and suppliers of industrial pneumatic actuators in China. As we have world-leading production equipment and strong manufacturing capabilities, we warmly welcome you to buy customized industrial pneumatic actuators from our factory.

Industrial pneumatic actuators are certified with CE, ATEX, and SIL3, and have been approved and produced in accordance with the latest technology, standards, and regulations for industrial and offshore applications. Depending on their type and protection class, these products are suitable for operation in hazardous (Ex) areas, including zones 0, 1, 2, 21, and 22. They are also suitable for outdoor use with IP ratings of IP65, IP66, IP67, and IP68, ensuring resistance to weather conditions, water, gases, vapors, mists, and dust. Industrial pneumatic actuators represent a modern, reliable, and proven solution for opening and closing pipeline valves in potentially explosive and harsh environments.

Modular Design

Employs standardized modular components, enabling rapid assembly and disassembly as well as flexible combination. Users can adjust cylinder size, stroke, or functional accessories according to actual working conditions, reducing customized production cycles. The modular structure decreases spare parts categories by over 40%, boosts inventory management efficiency by 30%, and shortens on-site maintenance downtime to within 2 hours.

Fully Enclosed Spring Module

The spring module features an integrated fully enclosed casing, isolating external dust, moisture, and mechanical impacts, and preventing spring fracture or jamming risks associated with traditional open designs. Under IP67 protection, it operates faultlessly for 100,000 cycles, with internal component displacement errors controlled within ±0.5mm during accidental pressure release, significantly lowering workplace accident probabilities.

CNC Machining Accuracy

Cylinder housings and piston rods are formed in one go by a horizontal CNC machining center, eliminating cumulative errors from multi-process manufacturing. Critical sealing surfaces achieve a roughness of Ra0.4μm, with fit clearance accuracy enhanced to ±0.01mm, ensuring an airtightness test leakage rate below 0.05L/min (standard conditions), reducing leakage risks by over 60% compared to traditional processes.

Low Friction Self-Lubrication

Guide rings and seals utilize PTFE composite materials, reducing friction resistance by 35% and enabling continuous operation without external lubrication. The dynamic sealing structure maintains over 90% sealing efficiency after passing a 2-million-cycle fatigue test under 2MPa pressure, quadrupling the lifespan compared to conventional rubber seals.

Torque Range: 100-500,000Nm

Through multi-stage gear sets and cylinder bore combinations, output torque spans five orders of magnitude, with a single cylinder capable of withstanding a maximum pressure of 8MPa. At the extreme torque of 500,000Nm, the driveshaft deflection angle is ≤0.1°, meeting the demands of heavy-duty valve opening and closing, mining machinery, and other ultra-high-pressure scenarios.

Wide Temperature Range Adaptability

Seal materials employ modified fluoroelastomer (FKM) and special silicone grease, with starting torque increasing by only 12% at -60℃ (ordinary products ≥50%). Standard actuators exhibit a torque fluctuation rate of ≤±3% within -20℃ to 80℃, adapting to Arctic-level low-temperature conditions without external heating devices.

Manual Emergency Devices

Integrates screw, gearbox, and hydraulic manual override units. The gear-type manual device requires an input force of only 25N to output 3000Nm torque, with a switching response time of <30 seconds. The hydraulic manual mode supports a 500:1 reduction ratio, suitable for emergency intervention in explosion-proof areas or during power outages.
