Application & Function
GW Triple Offset Flange Butterfly valve is used to prevent galling and scratches between the metal seat and the metal 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. Triple offset valves are generally used in applications which require bi-directional tight shut-off in oil and gas, LNG/NPG terminal and tanks, chemical factories, and shipbuilding. They are also used for dirty/heavy oil to prevent extrusion.
Accessories
Accessories such as gear operators, actuators, locking devices, chain wheels, extended stems and bonnets for cryogenic service and many others are available to meet the customer’s requirements.
