III. Product Features

• Dual Operation Flexibility: Electric actuator enables remote, automated control (integrated into SCADA systems), while the manual handwheel ensures operation during power failure or maintenance—critical for safety in process industries.
• Precise Flow Control: The globe valve’s disc-and-seat geometry, combined with electric actuator precision (±1% position accuracy), allows fine-tuned flow regulation for processes like steam pressure control in power plants.
• Corrosion Resistance: Stainless steel construction resists pitting, crevice corrosion, and chemical attack, extending service life in harsh environments (e.g., coastal or chemical plants).
• Visual and Digital Monitoring: Electric actuators feature position indicators, status LEDs, and optional digital communication (Modbus, HART) for real-time flow control monitoring.
• Easy Maintenance: Bolted bonnet and modular actuator design allow quick access to internal components (disc, seat, packing) and actuator servicing, minimizing downtime.

IV. Manufacturing Process

• Material Validation: Stainless steel/cast steel undergoes chemical analysis and mechanical testing (tensile strength, impact resistance) to meet standards. Actuator components are tested for electrical and mechanical durability.
• Precision Machining: Valve bodies, discs, and seats are CNC-machined to tight tolerances for proper sealing. Actuator gears and motors are precision-assembled for smooth motion.
• Actuator Integration: Electric actuators are mounted and calibrated to match the valve’s torque requirements, with manual handwheel gearing optimized for low-torque override.
• Seal and Packing Installation: Seats are brazed or press-fitted; seals (metal/soft) are installed for uniform contact. Packing glands are pre-compressed to prevent leakage.
• Testing and Calibration: Each valve undergoes hydrostatic shell test (1.5×pressure rating), seat leakage test (API 598 Class IV/VI), and actuator function tests (electric operation, manual override, position accuracy).
