Gate Valve

Valves

Gate Valve

Ringo Gate Valves provide full shut-off or complete flow opening through a wedge that moves perpendicularly. They are ideal for on-off applications where minimal pressure drop is required in the fully open position, offering tight sealing and robust construction.

Features and MaterialsDesign and Applications

Features

  • Tight Sealing: Linear movement of the wedge ensures reliable, leak-tight shut-off.
  • On-Off Operation: Designed for full-open/full-close operation, with no intermediate modulation.
  • Seat Options: Metallic or flexible seats selectable according to sealing requirements and fluid characteristics.
  • Robust Construction: Built to withstand high pressures and temperatures, ensuring durability.
  • Specialized Versions: Through-conduit and double block and bleed (DBB) options for high-safety and high-reliability applications.
  • Low Pressure Drop: Minimal pressure drop when fully open, optimizing system efficiency.
  • Wide Dimensional Range: Designed according to ANSI 150–2500 for a broad range of diameters and pressures.
  • Stem Sealing: Graphite/PTFE packing for high temperatures, ensuring long-lasting external sealing.
  • Limited Cycles: Optimized for a limited number of operating cycles to extend service life.
  • Low Maintenance: Requires minimal maintenance under normal service conditions.

Body Design

  • Screwed bonnet, bolted bonnet, or monoblock bodies designed for high-pressure/high-temperature service integrity.
  • Straight-through flow path minimizes pressure drop when fully open.
  • Manufactured according to standards such as API 600 and API 6D.
  • Size range: DN 15 to DN 1200 (or larger depending on design).
  • Pressure classes: ANSI 150 to ANSI 2500 or higher.

Construction Materials

  • Body Materials: Carbon Steel (A105, A216 WCB), Stainless Steel (304, 316), Duplex and Super Duplex Alloys, Nickel Alloys (Inconel, Hastelloy), Low-Temperature Carbon Steel (LTCS).
  • Trim Materials (Internal): Wedge/gate in stainless steel, carbon steel with wear-resistant coatings, or hardened alloys (Stellite, tungsten carbide); metallic or flexible seats; seals and packing in graphite, PTFE, or other temperature- and pressure-resistant materials.

Trim Design

  • Trim includes wedge/gate, seats, and seals to ensure leak-tight shut-off.
  • Seats can be metallic for severe applications or flexible for standard service.
  • Internal components are designed to resist erosion, corrosion, and high pressure, with coatings to extend service life.
  • Trim design ensures smooth, leak-free operation.

Applications

  • Fluid Isolation: Essential in water, oil, and gas networks for isolation functions.
  • General Services: Used in steam lines and general industrial services where modulation is not required.
  • Industrial Plants: On/off applications in various industrial plants where tight sealing is critical.
