Description

Electric two-way hard seal eccentric half ball valve 1

The Electric Two‑Way Hard‑Seal Eccentric Half Ball Valve 1 combines a rugged, hard-seal design with electric actuation to provide highly reliable isolation and flow control in critical industrial systems. Featuring an innovative double-eccentric mechanism, this valve ensures that the half-ball seats only in the final portion of the closing operation, minimizing friction, and reducing wear for extended service life. The hard-seal design—typically metal-to-metal with materials like Stellite or Inconel—delivers genuine bubble-tight shut-off, ideal for handling abrasive particles, corrosive fluids, or high-temperature media.

Built for automation, the valve includes an integrated electric actuator with feedback and positioning control, enabling precise remote operation via PLC or control systems. The low-torque metal-seated half ball profile requires minimal actuator force, making actuator sizing efficient. Available in full-bore or reduced-bore configurations, with bodies fabricated from carbon steel, stainless steel, or alloy steels, this valve meets industrial standards including API 6D, ASME B16.34, and IEC 60534.

Sealing integrity comes from the hard-seal eccentric seat, which withstands thermal cycles and pressure fluctuations without deformation—perfect for steam, petrochemical, power, and process industries. The valve’s two-way flow path simplifies installation and minimizes material retention, making it ideal for on/off isolation tasks. Electric actuation allows programmable open/close times, torque limiting, and potential for partial-opening control with high repeatability.

Safety features include anti-static grounding, blow-out-proof stem design, and optional fire-safe certification (API 607/6FA), ensuring secure operation in critical environments. The electric actuator is NEMA/IP rated for hazardous or outdoor areas, with manual override available for maintenance. ISO 5211 mounting ensures compatibility with various actuator types.

The valve is suitable for high-cycle environments and can operate reliably under temperature ranges from –40 °C to +200 °C with standard seals, or higher with metal seat versions. Integrated position indicators and limit switches support remote status monitoring. Fast quarter-turn operation, compact form factor, and robust materials minimize maintenance and maximize uptime.

Applications include isolation in steam systems, chemical feed control, abrasive slurry handling, gas processing, and automated emergency shut-down loops. The electric actuation supports network integration via protocols like Modbus, Profibus, or HART.

Choose the Electric Two‑Way Hard‑Seal Eccentric Half Ball Valve 1 for tight shut-off, electric actuation flexibility, long-term durability, and industrial-grade sealing performance—all with the precision and automation needed in today’s plants.
