The PAI EM56210 is a PP-1 push-pull valve with knob, identified for use in pneumatic control systems. As heavy duty diesel truck parts, push-pull valves commonly route or interrupt compressed air when the knob is moved, allowing an operator to control an air-operated circuit. MACK lists 20QE278P3 as the OEM reference; additional cross-references include 745-277663 and 277663.
