High-temperature electric valve

High-Temperature Electric Valve SUNRISE-08 AC220V – Nickel-Copper Wire; Electric Ball Valve, Flange Ball Valve, or Stainless Steel Ball Valve. Structure: Valve Body: The primary structural component, typically fabricated from cast steel, stainless steel, or alloys, offering high pressure resistance and corrosion resistance. The flow path configuration includes full-bore and reduced-bore variants. Ball: The core actuating component, typically coated with hard chrome or ceramic to enhance wear resistance; its through-hole geometry allows full opening or closing by rotating 90°. Valve Seat: The sealing ring, available in PTFE, metal, or composite materials, fits tightly against the ball to ensure superior sealing performance. Valve Stem: Connects the ball to the actuator to transmit torque; features a blow-out-resistant design to prevent dislodgement under high-pressure media. Electric Actuator: Receives control signals—such as a 4–20 mA current signal or digital on/off signals—to drive the ball rotation. Available types include switch-type and regulating-type; protection ratings reach IP67/IP68, with some models also possessing explosion-proof certification. Operating Principle: The control system issues a command; the electric actuator is energized to activate its motor, which, via a gear train, reduces speed while increasing torque. This drives the valve stem and ball to rotate 90° or a smaller angle, altering the positional relationship between the ball's through-hole and the pipeline, thereby achieving valve opening, closing, or regulation.
