Valve Piston

The Valve Piston (OEM 3115 3277 00) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. It is the central component that turns hydraulic pressure into the powerful percussive blows used to break rock, so its precision and finish directly affect drilling output.

Made from premium hardened steel with precision-ground impact and guide surfaces, it endures severe cyclic loading while holding tight clearances for efficient energy transfer. Supplied as an alternative spare part, it provides direct functional interchangeability and dependable performance at a competitive price.
