Questions about this product?

The Sealco 110500 spring brake control valve directs tractor supply air to the spring brake chambers first, allowing the spring brakes to release before the reservoir fills. Its internal pressure protection valve begins filling the reservoir at approximately 80 psi.

Designed for spring-brake-priority trailer systems, this valve has four 3/8-inch NPT delivery ports, a 3/8-inch NPT supply port, a 3/8-inch NPT control port, and a 1/2-inch NPT reservoir port. Match the existing circuit and reservoir connection before selecting a replacement.

Features and benefits

Spring-brake-priority operation Sends supply air to release the spring brakes before charging the reservoir.
