Sealco Spring Brake Exhaust Valve
One of the things often overlooked in heavy-duty air brake systems is the role of the spring brake exhaust valve. The Sealco Spring Brake Exhaust Valve releases air pressure from the spring brake chamber when the system is disengaged. With 1/4-inch NPT inlet and outlet ports, this valve is a common fit for numerous truck and trailer setups. It helps route exhaust air correctly so that spring brakes can return to their resting state when no longer needed, keeping the system functional and responsive during parking and emergency brake release events. The Sealco 3800 is an important component for retaining consistent system timing during air pressure changes.
