Air Control Valves | Use Air Signals to Control Flow for Safe, Non-Electric Automation. Explore our range of air-piloted control valves. They use a low-pressure air signal to shift the main valve spool, controlling the flow path without any electrical power. This makes them the inherently safe and reliable choice for hazardous environments like chemical plants or mining, or in applications with high moisture. Find the right valve for your non-electric control system now.

Our air control valves are expertly engineered to direct and manage airflow in your pneumatic systems with exceptional reliability. Ideal for applications requiring robust, non-electric actuation, these valves ensure smooth operation and precise control for a wide range of industrial automation tasks.
Operated by air signals (pilot-operated), offering dependable performance, especially in environments where electrical actuation is not preferred or feasible.
Constructed for longevity, our air control valves withstand demanding industrial conditions, ensuring consistent operation and minimal maintenance.
Available in various configurations (e.g., 3/2, 5/2, 5/3 way) to precisely manage air flow direction for single and double-acting actuators.
Air control valves, particularly pilot-operated types, use a small amount of air pressure (the pilot signal) to shift a larger internal spool or poppet. This action redirects the main airflow through different ports, controlling the operation of pneumatic cylinders, actuators, or other devices. This method allows for robust control without direct electrical input at the valve itself.
Engineered with optimized internal flow paths to provide maximum airflow (Cv/Kv) with minimal pressure drop, ensuring efficient actuator operation.
Precision-machined spools and high-quality, wear-resistant seals ensure long operational life and consistent performance.
Designed to operate reliably across a broad range of ambient and media temperatures, suitable for various industrial environments.
Many series offer manifold bases for compact assembly of multiple valves, simplifying piping and installation.
E.g., 3/2, 5/2, 5/3 (center closed, center exhaust, center pressure).
Thread size of inlet, outlet, and exhaust ports (e.g., G1/8, G1/4, G1/2).
Single air pilot, double air pilot.
Range for main air supply and pilot air signal.
Indicates the valve’s capacity to pass air.
Time taken for the valve to shift after pilot signal application.
Typically aluminum alloy for good strength and corrosion resistance.
Body ported or manifold mountable.

Directing airflow to control the movement (extend/retract, rotate) of pneumatic cylinders and rotary actuators.
Integral components in packaging machines, assembly lines, material handling systems, and robotic applications.
Used in various manufacturing processes for sorting, diverting, clamping, and other automated tasks.
Ideal for use in explosive or dust-prone areas where electrical components pose a risk.
Can be used to build purely pneumatic control circuits for specific sequencing or logic functions.
Pilot operation allows for remote actuation, while manual overrides offer convenient local control.
Always de-pressurize and de-energize the system before any installation, maintenance, or troubleshooting.
The primary difference is the actuation method:
While both control airflow, their means of activation and typical application environments can differ significantly.
This notation describes the valve’s function:
For example:
The minimum pilot pressure is the lowest air pressure required at the pilot port to reliably shift the main valve spool. This value is specific to each valve model and is usually listed in its technical datasheet.
It’s crucial to ensure your pilot signal pressure meets or exceeds this minimum requirement. If the pilot pressure is too low, the valve may not shift completely, may shift sluggishly, or may not shift at all, leading to system malfunction. The minimum pilot pressure can also vary depending on the main line pressure in some valve designs.
Yes, many air control valves are designed for manifold mounting. A manifold is a base block with common supply and exhaust passages, allowing multiple valves to be mounted compactly side-by-side.
Benefits of manifold mounting include:
