The PAI LEV-3640 Emergency Relay Valve is listed for Mack valve applications and uses a charging-style configuration. As heavy duty diesel truck parts, emergency relay valves use a control-air signal to direct supply air through a vehicle’s air-brake system, making port arrangement and cracking pressure important identification details. This valve has a 4â5 psig cracking pressure, two 1/4-inch NPT control ports, one 1/4-inch NPT emergency supply port, and four 3/8-inch NPT delivery ports.
