Valve Piston

The Valve Piston (OEM 3115 3111 00) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. As the core driver of percussive energy, it converts hydraulic pressure into the high-impact blows that fracture rock, making its dimensional accuracy and surface integrity critical to drilling efficiency.

Manufactured from premium hardened steel with precision-ground striking and guide surfaces, it withstands extreme cyclic impact loads while maintaining tight running clearances for maximum impact energy transfer. As an alternative spare part, it offers full functional interchangeability at a competitive cost, without compromising performance or reliability.

Backed by Delkom’s expertise in alternative rock drilling and drifter equipment, this part reflects the quality we export to over 100 countries. Reach out for availability, bulk pricing and technical support.
