2910300500 Complete Regulating Valve Service Kit For Oil-Injected Screw Compressor

Product Introduction

Pressure drift and sluggish modulation usually trace back to tired seals, not the controller. 2910300500 is listed by Atlas Copco as a kit regulating valve for oil-injected screw compressors, covering diaphragms, gaskets, O-rings, spring, filter, and small hardware needed to refresh the regulating valve in one service pass. The valve holds system pressure steady and keeps load/unload response predictable; once the membrane hardens or the seat leaks, the machine hunts pressure, sags under load, or over-generates air it cannot use.

Rebuild on fault diagnosis or scheduled valve service, never reuse old gaskets over the new set. Degrease the body, lay parts out in sequence, and check the spool, seat, and spring for wear while the valve is open—fitting fresh seals onto a damaged spool only delays the callback. Torque square and recheck for leaks after commissioning.

Confirm machine model and serial before dispatch; regulator kits change between production runs and applications such as XRH/XA/XAH-class portable units appear in supplier listings. Also called regulator valve kit, pressure regulating valve repair kit, TD service kit.
