Sealco Air Brake Relay Valve

Control response time in air brake systems often comes down to the relay valve. The Sealco Air Brake Relay Valve includes four delivery ports and a 3/8-inch NPT control port, offering a low 4.0 PSI crack pressure. That makes it highly responsive, which is especially helpful in long combination vehicles where lag can increase stopping distance. The Sealco 110416 supports fast relay of air signals to brake chambers, helping synchronize brake timing between axles.
