Pneumatic Control Valves
Pneumatic control valves available with options including bellows stem seals, extended bonnet, double packing or fined bonnet.
LowFlow Pneumatic Control Valves use compressed-air actuation to deliver fast, accurate, and repeatable flow control across a wide range of process conditions. The pneumatic actuator converts air pressure into smooth, proportional stem movement, giving engineers precise control over flow rate without manual adjustment, a capability that matters in automated and continuously monitored process systems.
Because the pneumatic control valve category spans multiple valve types and configurations, our distributors work directly with engineers and OEMs to match each application to the right valve body, actuator, and control characteristics.

Typical Applications
LowFlow Pneumatic Control Valves are used across process automation and research environments that require dependable, air-actuated flow control. Common applications include:
- Chemical Processing: Automated flow control for chemical process
- Pilot Plants and Research Facilities: Precise, repeatable regulation for testing and process development.
- OEM Equipment: Reliable actuation for integration into original equipment manufacturer systems.
- Process Automation: Fast, accurate response for automated control loops.
- Steam, Gas, and Liquid Control: Dependable regulation across a range of process media.
Sold through a worldwide network of representatives and distributors, LowFlow pneumatic control valves support facilities ranging from research laboratories to full-scale industrial plants. Whether the need is an urgent maintenance turnaround or a new facility build-out, LowFlow’s engineering team works with distributors to identify the right valve configuration for the application.
Valve selection should account for actuation requirements, process media, operating pressure, and system integration needs.
