Securaseal® metal-seated ball valves
Securaseal® metal-seated ball valves are built for high-to-ultra high temperatures, abrasive media, and corrosive environments. With a range of material options, they're designed to meet tough demands across various applications. Durable, reliable, and ready for extreme conditions.
Design
Velan offers a full range of Securaseal metal‑seated ball valves engineered to handle demanding applications at temperatures up to 1,000°F (538°C). The body wall thickness meets ASME B16.34 requirements, and the valves are dual‑qualified to fugitive‑emission standards API 641 and ISO 15848‑1.
Seat arrangements
Experience confident performance in every direction with bi‑directional sealing is achieved with a preferred flow direction. Beyond the standard seat design, Velan offers a wide selection of optional seat configurations tailored to specific applications, including crimped, bolted‑in, and spring‑loaded options.
Lower torque
An externally located tapered roller bearing provides lower dynamic friction which will result in lower overall valve torque, ensuring operability.
Body seal
Our proprietary designed body seal is a pressure energized metallic gasket construction with unique coating to withstand extreme high temperatures and high pressures in hydroprocessing applications such as ebullating bed hydrocracking services.
