Gate Valves

  • API 600/ISO 10434
  • 2" to 72"
  • ASME class 150 to 2500

Salient Features:

Body and bonnet - Cast with uniform sections, precision machined.

Body: Straight through port without recesses except in the seat area - Minimum resistance to flow, turbulence and erosion.

Flex wedge: Guide slots in the wedge engage with integral guide ribs in the body, Stem-to-wedge contact close to wedge centre - Better sealing, smoother operation.

Seal-welded seat ring - Eliminates leakage path between seat ring and body, does not loosen up due to temperature fluctuations or vibration.

Stem - One-piece construction with forged T-head - Long service life, smoother operation.

Globe Valve

  • BS 1873
  • 2" to 24"
  • ASME 150 to 2500

Salient Feature

Body and Bonnet - Cast with uniform sections, precision machined.

In-situ hard-faced body seat - Eliminates leakage path between seat ring and body.

Guided plug-type disc, Free-floating stem-disc connection - Uniform seating.

Check Valves

  • BS 1868
  • 2" to 36"
  • ASME 150 to 2500

Salient Features:

Body and Bonnet - Cast with uniform sections, precision machined.
Body: Permits full swing of disc on downstream side - Lower flow resistance and disc erosion.
Disc: Internally-hinged - No opening on the body, higher integrity.
Disc secured to hinge using lock nut and pin.
Disc free to rotate to avoid localized wear.
