Select a Spool or Air Solenoid Valve

Spool solenoid valve products from Duncan support directional control in pneumatic automation. IHPC Chennai can help match the valve function, porting, actuation, pressure and coil requirements to the current catalogue.

A spool valve redirects flow as its internal spool moves between defined positions. Solenoid actuation uses an electrical coil to initiate that movement directly or through a pilot stage.

For an air solenoid valve, provide the required ways and positions, port size, normal state, flow, pressure and coil voltage. If the system is hydraulic, state that clearly so IHPC can route the enquiry correctly.

Selection note: A micro solenoid valve, modular spool valve and Namur valve serve different installation and flow requirements.

Duncan Spool and Solenoid Valve Range

Compare modular, Namur and compact solenoid configurations from the current Duncan catalogue.

1/4 inch Modular Spool Valves - hydraulic solenoid valve

1/4 inch Modular Spool Valves

Duncan modular spool valve range for configured pneumatic control systems.

Namur Spool Valves - hydraulic solenoid valve

Namur Spool Valves

Namur-mounted spool valves for compatible actuator control requirements.

Direct Acting Midget Solenoid Valves - hydraulic solenoid valve

Direct Acting Midget Solenoid Valves

Compact direct-acting solenoid valve option from the Duncan catalogue.

How a Spool Solenoid Valve Directs Flow

When the solenoid or pilot stage is actuated, the spool shifts and connects selected ports inside the valve body. Returning the spool changes the flow path again.

The required function is defined by the port arrangement, number of positions, normal state and actuation method.

1
Valve function

Specify ways, positions and the required normal state.

2
Port and flow

Match connection size and flow demand.

3
Coil supply

Confirm voltage, frequency and connector requirements.

4
Mounting

Identify modular, Namur, in-line or manifold installation.

Typical Industrial Applications

Final suitability depends on the complete application and the current manufacturer technical data.

Pneumatic automation

Directional control for cylinders and actuators.

Machine sequencing

Electrically controlled air paths in production equipment.

Actuator control

Namur mounting for suitable rotary actuator arrangements.

Compact equipment

Smaller direct-acting valves where the circuit permits.

Spool Solenoid Valve FAQs

What is a spool solenoid valve?

It uses an electrically actuated mechanism to shift a spool and redirect flow between ports.

Is an air solenoid valve different from a hydraulic solenoid valve?

The operating medium, pressure and internal construction can differ. Always state whether the circuit uses compressed air or hydraulic fluid.

What information is needed for selection?

Provide ways, positions, port size, normal state, pressure, flow, voltage, mounting and environment.

What is a micro solenoid valve?

It is a compact solenoid-operated valve. Its flow capacity and connection style must still match the application.
