2Q Series

Direct Acting, Double Acting
Port Size: 3/8"–2"
Fluid Temperature: -5°C to 180°C
Operating Pressure: 0–1.0MPa
Media: air, water, oil, gas

2Q Series pneumatic control valve is used in a wide range of industries, such as oil and gas, chemical processing, mining, metallurgy, petrochemical, pharmaceutical, food processing, industrial cleaning, automotive spray painting, and other general machinery industries. This valve is esigned for explosion-proof, corrosion-resistant, and wide-temperature applications (–10 °C to 180 °C), and performs reliably even in space-limited environments where traditional electric valves fail to meet safety or performance requirements.

Features

Intrinsically safe pneumatic drive, no electrical input, which completely eliminates spark hazards
PTFE-coated valve stem and piston provide excellent corrosion resistance to corrosive media (e.g., water, gas, liquid)
Compact actuator designed, 30%–50% smaller than similar products, which saves installation space
Modular design supports tool-free and quick disassembly, and fast actuator replacement within one minute
Low-pressure start with high sensitivity ensures excellent sealing and flexible installation in any flow direction
Available in double-acting or spring-return (single-acting) configurations to meet different fail-safe requirements
Optimized flow path and precision machining ensure stable response across the full pressure range and extended service life
