Triple Offset Butterfly Valves are an evolution of the Double Offset Butterfly Valve, taking high performance buttefly valves to the next level. They employ the same offsets as the double offset valve, in that the shaft and disc are moved out of the centreline of the valve and pipework.
The third offset involves the conical machining of the sealing components, which ensures that after the first 0.1 of a degree of the operating cycle, the disc is totally friction free. Not only does this increase reliability and reduce wear on sealing components, it also reduces the torque required to open/close the valve, and therefore reduces actuation costs and energy consumption.
The Triple Offset Butterfly Valve design also ensures that any potential leak paths are eliminated, thereby offering superior performance. Triple Offset Butterfly Valves are generally used in critical applications where safety and high performance are primary considerations. They are available in a wide range of materials including Stainless Steel, Monel, Duplex and other exotic alloys. They are available to suit a wide range of process media including steam, abrasive dust and slurries and aggressive liquids and gases.
