Pneumatic Air Solenoid and Pilot control-valves

Air Pneumatic Control Valves

Directional Air Control for Automated Pneumatic Machinery

Pneumatic air control valves direct compressed air to cylinders, actuators and other devices so automated machinery can start, stop, extend, retract or change direction. PneumaticHub supplies control valves in common 2-way, 3-way and 5-way configurations for industrial automation and OEM equipment.

The range includes pilot-operated and solenoid-operated designs with multiple port sizes, materials and seal options. Correct valve selection depends on required flow, pressure, function, actuation method, electrical requirements and environmental conditions.

Why Use Pneumatic Control Valves?

Control valves are the switching element of a pneumatic circuit. They determine where compressed air flows and how an actuator responds to an electrical, pneumatic or manual command.
Choosing a valve with adequate flow capacity and the correct number of ports and positions is important for cylinder speed, system efficiency and reliable machine operation.

Common Applications

Pneumatic cylinders and actuators
Packaging and assembly machinery
Automated fixtures and clamps
Material handling equipment
Machine guarding
Robotics and OEM automation

Frequently Asked Questions

What does a pneumatic control valve do?

It directs or blocks compressed air to control cylinders, actuators and other pneumatic devices.

What is the difference between 3-way and 5-way pneumatic valves?

A 3-way valve is commonly used with single-acting actuators or signal functions, while a 5-way valve is commonly used to control double-acting cylinders.

What is a pilot-operated air valve?

A pilot-operated valve uses a pneumatic pilot signal to shift the main valve mechanism and redirect airflow.

How do I size a pneumatic control valve?

Consider actuator bore and stroke, required cycle speed, supply pressure, tubing size, port size and the valve flow rating.

What is a manual override on a solenoid valve?

A manual override allows the valve to be shifted mechanically for setup, testing or troubleshooting without energizing the solenoid.

Can pneumatic control valves operate vacuum?

Some models can handle vacuum service, but the exact allowable vacuum range must be confirmed from the individual valve specification.

What seal materials are available?

Nitrile is common for general pneumatic service, while Viton or silicone may be available for applications requiring different chemical or temperature compatibility.
