Description

Electric two-way hard seal eccentric half ball valve 3

The Electric Two‑Way Hard‑Seal Eccentric Half Ball Valve 3 integrates high-performance flow control with electric remote actuation to meet the demands of modern industrial systems. This valve, designed as an electric eccentric half ball valve with hard-seal precision, features a double-offset mechanism that minimizes wear by engaging the seat only at the final stage of operation. It employs robust metal-to-metal seals—in alloys like Stellite or Inconel—ensuring true bubble-tight isolation even under high pressure, abrasive, or corrosive conditions. This metal-seated eccentric electric valve is ideal for critical services where soft seals are insufficient.

With built-in electric actuation, this valve functions as a two-way electric hard-seal ball valve, offering programmable open/close timing, position feedback, and torque adjustment to match specific system requirements. The half-ball design translates into low-torque operation, enabling compact electric actuators and efficient system integration. Constructed from carbon steel, stainless steel, or high-grade alloy, the valve body accommodates full-bore or reduced-bore flows and performs consistently across a wide temperature range—up to 200 °C with soft seats and higher with metal-seated versions. It complies with API 6D, ASME B16.34, IEC 60534, and ISO 5211 standards for mechanical and actuation compatibility.

This electric actuated half-ball isolation valve excels in environments requiring frequent or automated cycle control, such as steam control loops, chemical dosing systems, slurry pipelines, and safety shutoff circuits. As a metal-seated eccentric ball valve, its hard-seal technology resists seat erosion, thermal cycling, and abrasive wear, making it a highly durable option for demanding services. The two-way valve configuration ensures flow in both directions and simplifies installation by eliminating additional check valves.

Safety features include anti-static grounding, blow-out-proof stem, and optional fire-safe certification per API 607/6FA. The electric actuator is NEMA/IP rated for industrial or hazardous environments, offers manual override, position indication, limit switches, and torque feedback for safe and reliable operation. This electric two-way valve delivers fast actuation and high sealing integrity, suitable for remote control via PLCs and network protocols like Modbus, Profibus, or HART.

Plant engineers value this valve for its reliable operation in critical systems—steam, petrochemical, water treatment, or power generation—where precise flow shut-off and durability are essential. The combination of an electric eccentric half ball valve’s low torque profile, two-way hard-seal function, and electric control makes it a preferred solution for automated industrial processes requiring high integrity isolation and minimal maintenance.
