P/N 637374-3 ARO Major Air Valve Assembly
The ARO 637374-3 Major Air Valve Assembly is a replacement service assembly for the major air valve of compatible ARO air-operated diaphragm pumps. ARO identifies this assembly for use in applicable pump configurations requiring the corresponding major valve arrangement.
The assembly includes the major valve block and applicable internal valve components, seals, gaskets, and mounting hardware required for replacement of the major valve assembly. It provides a complete service assembly rather than an individual air-valve component or seal kit.
Please verify your complete pump model and air-valve configuration before ordering to ensure compatibility. This is a major air valve service assembly only and is not a complete air motor or pump.
