L&T Valves manufactures a wide variety of Gate, Globe & Check Valves in bolted-bonnet design. The valves are approved by the global majors in oil & gas and power and have a reputation for reliable performance in critical services, across the globe. Valves in bolted bonnet construction are available in pressure classes from 150 to 2500, in a variety of materials and end-connections. 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 Valves BS 1873 2" to 24" ASME 150 to 2500 Salient Features: 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.
