The PAI LFV-5544 is a Benchmark single circuit valve with one 1/2-inch supply port, one 1/8-inch supply port, five 1/4-inch supply ports, two 1/4-inch delivery ports, and three 3/8-24 mounting studs. As heavy duty diesel truck parts, single circuit valves manage air routing within a pneumatic system by directing supplied air through designated delivery ports. These port sizes and mounting-stud specifications provide useful details for matching the valve to the existing air lines and mounting arrangement.
