The S&S^® HPB Series™ Double Offset Butterfly valves deliver reliable, high-capacity control for demanding applications where performance, durability, and versatility are essential. Its double-offset disc design minimizes seat wear and reduces operating torque, while the free-floating, pressure-assisted seal provides tight shutoff across both low- and high-pressure conditions.

Built for service in oil and gas, refining, power generation, chemical processing, and emerging energy applications, the HPB1 combines the efficiency of a compact, quarter-turn valve with the strength and sealing performance of a true high-performance butterfly design. It is available in soft seat, metal seat, and fire-safe configurations, and in multiple body styles including wafer, lug, and double-flanged, making it well-suited for a wide range of pressures, temperatures, and media.
