Ball valves / LIANGGU
Forged Steel Metal Seated Ball Valve
This model is a ball valve distinguished by matched metal ball and seat surfaces designed for abrasive or elevated-temperature service. For a project quotation, share the required size, pressure designation, materials, seating, connections and quantity. Final suitability is confirmed against the approved specification.
PRODUCT DETAILS
Understand this valve.
Working principle
a quarter-turn stem rotates a bored ball between open and closed positions; seat design, ball support, body construction, cavity pressure management, and operating torque determine service suitability; verify temperature and required leakage class
Typical applications
slurry, catalyst handling, high-temperature fluids, erosive media, and severe on-off duty
Selection priorities
solids content, temperature, required leakage class, cleaning action, actuator margin, surface finish, and hard-facing system
