Hendrickson Air Brake Pressure Protection Valve

If you’re dealing with air systems that don’t balance properly, the Hendrickson Air Brake Pressure Protection Valve may be the fix. This valve protects downstream systems by controlling when pressure is allowed through—triggering only when the required PSI is reached. With 1/4-inch NPT ports, this unit installs into systems requiring controlled air distribution to brakes, accessories, or reserve tanks. The Hendrickson VS-38941 also helps separate vital functions from auxiliary ones, directing airflow only when pressure thresholds are met.
