High Temperature Power Station Gate Valve – YONCO PN250 to PN320
The YONCO High Temperature Power Station Gate Valve (Z61Y Series) is a specialized, heavy-duty isolation valve specifically engineered for the extreme conditions of thermal power plants. Designed with a unique Pressure Seal Bonnet (PSB), the sealing reliability actually increases as system pressure rises. Featuring a rigid single wedge, butt-weld ends, and premium WC9 alloy steel construction, this valve excels in handling high-pressure water and non-corrosive steam at temperatures up to 570°C. It is the ultimate solution for safe, leak-proof fluid control in critical power generation pipelines.
Core Features & Advantages
- Pressure Seal Bonnet (PSB): Utilizes a unique self-sealing design where higher internal pipeline pressure creates a tighter, more reliable seal, ensuring absolute safety in extreme high-pressure environments.
- Frictionless Operation & Self-Cleaning: Engineered to eliminate friction between sealing surfaces during opening and closing. When the gate tilts away from the seat, fluid flows evenly at 360 degrees, preventing localized erosion and washing away debris for a self-cleaning effect.
- Top-Entry Structure for In-Line Maintenance: The advanced top-entry design allows for rapid online inspection and maintenance without removing the valve from the pipeline, significantly reducing plant downtime and maintenance costs.
- Low Torque & Anti-Overpressure Design: Features a specialized stem design requiring minimal torque for effortless manual operation. The single-seat design eliminates the risk of abnormal pressure buildup in the valve cavity, enhancing overall system safety.
- Hard-Faced Seating: Sealing surfaces are hard-faced with premium hard alloy, offering exceptional resistance to high-temperature galling, steam erosion, and wear.
