Triple Offset Butterfly Valve

Triple Offset Butterfly Valve is used to prevent galling and scratches between the seat and the disc. Due to its unique design, the only time where the seal comes into contact with the seat is at the point of complete closure. It is generally used in applications which require bi-directional tight shut-off in oil and petroleum, refinery and tanks, chemical factories, steel mills and shipbuilding industries.

EG Valves have over 15 years experiences, we always strive to keep good quality and competitive prices for all our global valued customers.
