Double Overcenter Valve

The Double Overcenter Valve (OEM 550 853 81) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. It routes and regulates hydraulic fluid flow through the circuit, controlling the precise operation of drilling and feed functions.

Made to precise tolerances from hardened, wear- and corrosion-resistant materials, it delivers accurate flow control, tight sealing and reliable response under high pressure. As a cost-effective alternative component, it matches the form, fit and function of the original while maintaining high reliability.
