Products Kirloskar Cast Steel Gate Valve

Kirloskar Cast Steel Gate Valves are heavy-duty industrial valves engineered specifically for isolating flow in pipelines dealing with high-temperature, high-pressure, or corrosive fluid media. Manufactured by Kirloskar Brothers Limited (KBL), these valves feature a rigid, Outside Screw and Yoke (OS&Y), rising stem design, making them highly trusted across petroleum refineries, thermal power plants, and chemical processing facilities.

Core Technical Specifications

  • Design Standards: Engineered in strict compliance with API 600 or BS 1414; tested dynamically to API 598 protocols.
  • Size Spectrum: Standard inventory spans from 50 mm to 600 mm (with custom industrial layouts up to 1200 mm).
  • Pressure Ratings: Extensively available in Class 150, Class 300, and Class 600.
  • Material of Construction (MOC):
    • Body & Bonnet: ASTM A216 Grade WCB (Cast Carbon Steel).
    • Wedge: Flexible or solid WCB wedge designed to maintain tight seals under thermal expansion.
    • Stem & Shaft: High-tensile SS410 stainless steel.
    • Trim Configuration: 13% Chromium facing (13% Cr) on body seats and wedge faces for exceptional wear resistance.
  • End Connections: Double-flanged raised face (ANSI RF) or Butt-weld ends.

Key Performance Benefits

  • Leak-Proof Integrity: Precision-ground and lapped seating surfaces offer strict shut-off parameters vital for hazardous setups.
  • Minimal Pressure Loss: The full-bore straight-through path ensures minimal friction loss across the pipeline during full open states.
  • In-Line Repacking: Features a back-seating bush arrangement allowing the stem packing to be replaced safely while the valve is wide open under full operational pressure.
