Triple Eccentric Butterfly Valve

Name: Triple Eccentric Butterfly Valve
Brand: VTXFLOW

Metal-seated, zero-leakage, fire-safe for high P/T service.

Butterfly Valve Series

Triple Eccentric Butterfly Valve

The third offset gives a cam-like, non-rubbing metal seal: zero leakage, bidirectional, fire-safe. Triple-offset valves replace gate valves at large diameters in refineries, LNG and steam systems at a fraction of the weight.

As part of the VTXFLOW butterfly valve range, every triple 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.

Metal-to-metal, zero-leakage ISO 5208 Rate A
Bidirectional tightness, fire-safe API 607
Laminated SS+graphite seal ring, replaceable
Sizes to DN2000, Class 150–600
