Spring Brake Air Valve-110700

Sealco spring brake air valve part number 110700. 

When supply line pressure is charged and the reservoir has adequate pressure the 110700 will use reservoir air to release the spring brakes. This provides for the fastest possible release times. Should the reservoir be empty the 110700 simultaneously fills the spring brakes and the reservoir. This is called “Service Brake Priority”. When trailer air reservoir is full, the valve delivers air to spring brake chambers immediately due to the valve’s relay feature.
