Flow-Tek's Series S20 threaded ball valves offer a compact, one piece body design to the Bray family of products. The one piece body supplies maximum structural strength while minimizing the number of potential leak paths.
These valves feature quarter turn operation, bottom entry blowout proof stems and low operating torque. Live-loaded, self-adjusting stem seals automatically adjust to compensate for changes in wear and temperature. Series S20 Valves are available in both standard and fire safe versions.
