Triple Offset Butterfly Valves
Series T high performance triple offset butterfly valves are manufactured under international standards (API 609, EN 593, MSS-SP67). These valves are engineered for durability, constituent performance and ease of automation. Each valve is 100% pressure tested and fully serialized prior to shipment.
QUEST Flow Controls serves the oil, gas, and petroleum industry with valves designed for extreme pressures, temperatures, and corrosive media encountered across exploration, production, refining, and distribution. Our triple offset and double offset butterfly valves offer zero-leakage shutoff with metal and laminated seat options suitable for high-temperature hydrocarbon service, while our floating ball valves are fire-safe certified to API 607/6FA with secondary metal-to-metal sealing. Live-loaded packing systems with Belleville washers ensure fugitive emission compliance, and NACE MR0175/ISO 15156 compatibility addresses sour gas environments. From pipeline isolation and process control to tank farm and terminal operations, QUEST valves deliver dependable performance in the most demanding conditions.
