UNLOADER VALVE KIT FOR OIL INJECTED SCREW COMPRESSORS

The unloader valve governs whether the airend — the rotating element that compresses the air — draws in and delivers air or runs unloaded when demand drops, and this unloader valve kit (2901000201) supplies the parts to restore that function during routine service. As a service kit it brings together the parts that are replaced at the same time, so they are renewed as a set rather than piecemeal, helping the compressor hold pressure and load and unload cleanly.

This kit suits the GA11-30 range of oil-injected screw compressors rated up to about 40 hp (30 kW). It is the correct part for those machines, though before ordering it is worth checking it against the unloader valve assembly currently fitted to your compressor and against that machine's parts list. If you are unsure which valve your unit carries, or you want the kit contents confirmed before you book the service visit, contact us with your compressor details and we will match the kit to it before you order.
