Bevel Gear Operated Gate Valve – YONCO PN16 to PN160

The YONCO Bevel Gear Operated Gate Valve (Z540 Series) is a heavy-duty isolation valve specifically engineered for high-pressure and large-diameter pipeline systems. Featuring a high-efficiency bevel gear actuator for effortless operation, this flanged, OS&Y (Outside Screw and Yoke) elastic wedge gate valve delivers exceptional bi-directional shut-off performance. Manufactured in robust materials including carbon steel, Cr-Mo alloy steel, and premium stainless steel, it handles nominal pressures from PN16 to PN160. It is the ultimate fluid control solution for water, steam, oil, and highly corrosive media across demanding industrial applications.

Core Features & Advantages

  • Bevel Gear Actuation: Equipped with an enclosed, high-efficiency bevel gear operator that significantly reduces operating torque, allowing for smooth, labor-saving manual operation even in high-pressure or large-bore applications.
  • Elastic Wedge Design: The flexible single wedge disc automatically compensates for seat distortion caused by pipeline stress or thermal expansion, ensuring reliable sealing and preventing the gate from jamming during extreme temperature fluctuations.
  • Premium Hard-Faced Seating: Seat sealing surfaces are hard-faced with iron-based alloys, stellite (hard alloy), or standard stainless steel, providing superior resistance to galling, abrasion, and erosion for a vastly extended service life.
  • Advanced Stem Sealing: Utilizes high-quality flexible graphite or PTFE packing (tailored to specific media and temperatures), ensuring strict fugitive emission compliance and zero-leakage stem performance.
  • Robust Material Selection: Valve bodies are fully customizable, available in carbon steel (up to 425°C), Cr-Mo alloy steel for high temperatures (up to 550°C), and austenitic stainless steel for highly corrosive acidic environments.
