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.

Close Bonnet safety valve is another popular type of safety valve which contains the fluid entirely and helps to discharge it in the system. This fluid is not vented to the air. For different types of power vessels these vents are mostly used. The spring enclosure is widely used and considered useful for valves with small screw. At present these valves have become quite common and different ranges of such valves are available in the market.  The ranges of spring valves mainly depend on the steam and discharge of fluid. The fully closed bonnets are becoming extremely popular in recent days. We being the leading distributor of this product have it in various sizes and ranges to cope up with the exact need of the customer Long life High performance Best in quality
