High-performance double-offset for longer seat life.

Butterfly Valve Series

Double Eccentric Butterfly Valve

Double-offset geometry lifts the disc off the seat within the first degrees of opening, cutting seat friction and wear — a high-performance valve for water transmission, HVAC district networks and industrial process lines.

As part of the VTXFLOW butterfly valve range, every double eccentric butterfly valve is produced under our certified quality system — from in-house casting and CNC precision machining to 100% pressure and seat-tightness testing before shipment, with EN 10204 3.1 material certificates supplied.

Double-offset — friction-free after 3° opening
PTFE / RPTFE or metal laminated seats
