New Triple-Offset Butterfly Valves’ Unique Design Features
To coincide with celebrations of Shipham Valves reaching its 225th year of operation, the business is delighted to expand its range of high-performance butterfly valves, with the launch of a new innovative range of triple-offset butterfly valves.
Triple-Offset Butterfly Valves Design Features
Several unique design features are incorporated in this range to reflect the wide range of applications they support, delivering a high-performance, robust and effective through-life isolation valve solution. As well as providing weight and space-saving benefits, the anti-rotational laminated seat design ensures no movement in service to maintain consistent sealing performance, when compared to a clamped design.
Effective Sealing
Shipham Valves’ Triple-Offset design delivers fast opening and closing quarter turn operations and employs a uniform profile around the conical sealing face to ensure effective sealing is achieved.
Three different body types available include:
- BU04 – Wafer-Type
- BU05 – Lug-Type
- BU06 – Double-Flanged
Shipham Valves, Head of Engineering & Quality, Nick Gray comments “We are pleased to announce the launch of our brand-new range of Triple-Offset Butterfly Valves. This new range has undergone a comprehensive product design, development verification and validation process to deliver a high-performing, effective and robust triple-offset butterfly valve solution meeting all the requirements of an API 609 Cat. B product.
Nick continues “For total reassurance, our triple-offset range design is fire-safe certified in accordance with API 607, which provides fire test criteria for quarter-turn valves with non-metallic seating, when the valves are exposed to certain fire conditions and pressure”.
