Boosting Industrial Automation with the 3-Way Pneumatic Ball Valve (L-Port)
We are a top-tier control valve manufacturer in China, delivering high-quality valves and control actuators designed to meet a wide range of industrial applications.
In today’s fast-paced world of industrial automation, efficiency, reliability, and precision are more critical than ever. The introduction of the pneumatically controlled 3-way ball valve (L-port) represents a major step forward in automating fluid control systems. Replacing manual valves, this intelligent solution offers seamless integration into automated environments, increasing operational performance while reducing long-term costs.
Compact, Capable, and Versatile
Engineered for versatility, this 10 mm valve effectively handles both liquids and gases across a temperature range of -10 to 100°C, making it suitable for a wide array of industrial applications. With G 3/8" threaded ports and a Kv value of 3 m³/h, it ensures optimal flow control and easy system integration.
Precision Through Pneumatics
At the core of this system lies a robust pneumatic actuator delivering up to 9.92 Nm of torque at 8 bar, operating reliably within a 6 to 10 bar control pressure range. The double-acting aluminium rack-and-pinion design guarantees precise, responsive valve movements, essential for time-sensitive or highly automated processes. Housed in anodized aluminum with a durable acetal resin cover, the actuator resists corrosion and mechanical wear, ensuring long service life.
Built to Withstand Pressure
The valve body is crafted from brass for excellent strength and pressure resistance (up to 40 bar), while PTFE seals offer superior chemical resistance and minimal friction. This combination guarantees consistent, long-lasting performance under demanding conditions.
Smart Design, Seamless Control
The actuator is equipped with G1/8” air ports and a mechanical position indicator. Most notably, it supports direct mounting of a 1/4” Namur solenoid valve, minimizing the need for extra fittings and reducing complexity in system design.
Certified for Hazardous Environments
Safety is non-negotiable in industrial settings. That’s why this valve is ATEX certified (EX II 2GD c) for use in potentially explosive atmospheres—an essential feature for oil & gas, chemical processing, and other high-risk environments.
Why Choose a Pneumatic 3-Way Ball Valve?
✅ Pros:
- Direct Mounting of Namur Solenoid Valve – Clean, compact installation with fewer leak points.
- Mechanical Position Indicator – Quick visual confirmation of valve status.
- ATEX Certified – Approved for use in explosive atmospheres.
- Lower Initial Cost vs. Electric Actuators – Ideal for cost-conscious automation upgrades.
- Fast Actuation – Rapid response improves process control.
- Double-Acting Actuation – Greater precision and feedback control.
- Limit Switch Box Compatible – For enhanced monitoring and system integration.
⚠️ Cons:
- Higher Air Consumption – Double-acting design requires more compressed air.
- Needs Compressed Air Infrastructure – Requires solenoid valve and air supply system.
- Ongoing Energy Use – May have higher long-term energy costs than electric options.
Final Thoughts
The 3-way pneumatic ball valve is more than just a flow control device—it’s a smart investment in automation. Its performance, reliability, and ease of integration make it a standout choice for industries seeking greater control with lower upfront costs. Whether you're retrofitting an existing process or designing a new automated system, this valve delivers on all fronts.
In an era where operational efficiency defines competitiveness, this compact yet powerful solution helps future-proof your systems with minimal complexity and maximum return.
