Questions about this product?

The Fabco-Air 18HL-4 is a four-way, two-position pneumatic directional-control valve with a detented hand lever and 1/8-inch NPT ports. The lever stays in the selected position rather than spring-returning when released.

Use this valve where the air circuit calls for maintained manual switching. Its five-port arrangement supports single-inlet/dual-exhaust or dual-inlet/single-exhaust plumbing. Confirm the circuit and port connections before replacing another valve; two lever positions do not make this a two-way valve.

Maintained manual air control

Feature Benefit
Detented hand lever Holds the selected valve position without continuous hand pressure.
Pressure-balanced spool Supports consistent manual switching as the valve directs airflow.
Aluminum body and Delrin spool Combine a metal valve body with a lightweight short-stroke spool.

Before ordering

Check What to confirm
Circuit Match the required port routing and maintained lever action; this is not the spring-return 18HLS-4.
Vacuum Suitable for vacuum directional flow, not for holding vacuum.
Heat For continuous operation from 150°F to 180°F, confirm seal suitability and the manufacturer’s Viton-option guidance.
Install Verify port connections and clear lever travel. Isolate the air supply and release trapped pressure before service.
