Valve Review: Piston Valve | FCT Valve
Piston valves are closing-down valves in which a piston-shaped closure member intrudes into or withdraws from the seat bore
www.fctvalve.comThe piston valve operates with a cylindrical piston that moves vertically inside the valve body, and high-temperature sealing rings around it to create a tight shutoff to enable reliable isolation in steam and hot-fluid systems; They are used in steam and condensate manifolds, pressure-regulating stations, and high-temperature fluid lines to minimize leakage and ensure precise control; They provide positive shutoff similar to globe valves while maintaining effective performance across different flow conditions; The sealing approach uses a piston-based surface to enhance tightness and control; Industries rely on steam systems, condensate lines, and high-temperature pipelines to protect against leaks and ensure accurate regulation; In operation piston valves offer robust isolation where high temperatures and demanding media prevail; Types focus on seal materials and actuation, optimizing durability in harsh service environments; In summary these valves balance tight shutoff with smooth modulation for reliable high-temperature control.
