2Q series air control pneumatic valve with PTFE seals

Product Advantages

✔  Compressed air control (replaces solenoid actuation) for enhanced safety in explosive environments.
✔  PTFE-coated valve stem/piston resists various media (water, gas, liquid).
✔  Compact actuator design with 30-50% smaller footprint than pneumatic control valves.
✔  Robust construction ensures long service life.
✔  Tool-free actuator replacement within 1 minute saves time and labor.

Product Description


The 2Q Pneumatic Control Valve is a robust and safety-engineered solution designed for reliable operation in hazardous and demanding industrial environments. Its intrinsically safe pneumatic actuation eliminates electrical spark risks, making it particularly suitable for flammable and explosive atmospheres where traditional electrically-operated valves would pose significant safety concerns. The valve incorporates high-performance PTFE sealing components that maintain their integrity in aggressive chemical environments, extreme temperatures, and other challenging operating conditions while ensuring long-term, leak-free performance.

Featuring a modular design, the 2Q valve allows for straightforward disassembly and maintenance using basic tools, with quick-access actuator and piston seal components that can be easily serviced or replaced without specialized equipment. The series offers flexible configuration options, including both double-acting and spring-return (single-acting) variants to accommodate different operational requirements and fail-safe scenarios. Its compact actuator design achieves a remarkable 30-50% size reduction compared to conventional pneumatic actuators of equivalent capacity, providing significant space savings in crowded control panels or equipment installations where real estate is limited.

The valve’s optimized airflow path and precision-machined internal components ensure responsive actuation and consistent performance across its full pressure range. The corrosion-resistant body materials and rugged construction make it suitable for long-term service in oil & gas, chemical processing, mining, and other industries where equipment reliability directly impacts safety and productivity. Available in multiple port sizes and with various mounting configurations, the 2Q series can be adapted to specific application needs while maintaining its signature combination of safety features, compact dimensions, and maintenance-friendly design.

With its balanced focus on operational safety, space efficiency, and serviceability, this pneumatic control valve provides plant operators and system designers with a dependable solution for critical fluid control applications in hazardous locations. The series meets relevant industry standards for explosion-proof equipment and continues SENYA’s tradition of delivering practical, well-engineered solutions for challenging industrial applications where conventional approaches may compromise safety or performance.
