The PAI EM40740 is a trailer valve with one 3/8-inch P.T. supply port, one 1 1/4-inch P.T. control port, and one 1 1/2-inch P.T. reservoir port. Its configuration also includes four 3/8-inch P.T. service brake ports, two 3/8-inch P.T. spring brake ports, and 3 psig cracking pressure, details that distinguish this air-brake component among heavy duty diesel truck parts. A trailer valve manages compressed-air routing between control, reservoir, service-brake, and spring-brake circuits. MACK lists 5396-KN28601 as the OEM reference; selected cross-references include HALDEX KN28601X and MACK 5396-N4304AB.
