Control SealTriple Offset High Performance Butterfly Valves

SHARE
Control Seal's triple offset butterfly valves are designed to ensure zero leakage through precise engineering. The unique offset angle of the seat and seal results in even seat loading, eliminating wear-inducing friction during operation. These valves cater to various industries, including LNG, hydrocarbon processing, geothermal steam, and more. They are specifically engineered to handle extreme temperatures ranging from -196°C to 820°C and pressures from 150# to 2500#, with customizable connection and material options. The design adheres to rigorous standards such as API 6D and ASME B16.34, ensuring reliability where other valves may fail. Featuring non-rubbing seating surfaces and multiple actuator options—pneumatic, electric, hydraulic, or manual gear—the valves retain their effectiveness and longevity over time. Control Seal emphasizes a solution-oriented approach, tailoring its products to meet distinct project requirements and offering competitive pricing and strong after-sales support.
