The Linear Pneumatic Actuator is a precision-engineered straight-stroke pneumatic actuator designed for reliable valve control in industrial settings. As a core component of industrial valve automation, it delivers consistent performance to drive wedge gate valves, globe valves, knife gate valves, and other linear-motion valves. Powered by purified compressed air (0.4-1.0MPa gauge pressure), this actuator pushes a piston to regulate valve opening and closing, making it ideal for critical applications like safety shut-off valves and control valves. With advanced technology, corrosion-resistant materials, and flexible operation modes, it has become a trusted choice for pipeline systems across petroleum, chemical, metallurgy, and power industries. Its robust design ensures long service life, while easy maintenance and customization options adapt to diverse working conditions—setting a benchmark for efficiency in linear valve actuation.
| Applicable media | Body material | |||

| Special media | Natural gas medium containing hydrogen sulfide;Coal powder and aluminum powder conveying system for steel and nonferrous metal smelting;It is used for pulp conveying and other media containing particles and short fibers in the paper industry. | |||
The linear actuation principle ensures precise valve positioning, with smooth piston movement that minimizes wear and tear. This design guarantees consistent performance even in high-cycle applications, reducing downtime for maintenance.
Crafted from anodized aluminum alloy and stainless steel, the actuator resists harsh industrial environments—including corrosive media like nitric acid and acetic acid. The anti-corrosion treatment extends service life in wet or chemical-exposed settings.
Supporting double-acting, single-acting, and manual/hydraulic/spring-assisted modes, it adapts to diverse system requirements. The fault hold position feature adds safety by maintaining valve status during air supply interruptions.
With a working pressure range of 0.4-1.0MPa, it integrates seamlessly with standard industrial compressed air systems. The 0.6MPa airtight seal test ensures leak-proof operation, critical for high-pressure pipeline applications.
Convenient disassembly and accessible components simplify routine checks. The optional top-mounted or side-mounted manual mechanism allows manual operation during power outages, enhancing operational flexibility.
Engineered for heavy-duty use, the actuator handles nominal pressures up to 10.0MPa (PN10) and Class 600, making it suitable for high-pressure pipeline systems in petroleum and power industries.
Petroleum & Chemical Industry: Ideal for pipeline opening/closing in refineries, chemical plants, and liquefied gas storage facilities—compatible with oil, natural gas, and corrosive chemical media.
Metallurgy & Electric Power: Used in coal powder/aluminum powder conveying systems for steel smelting and steam valve control in power plants.
Shipping & Marine Engineering: Reliable for marine pipeline systems, with corrosion resistance to saltwater environments.
