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.
