API600 GATE VALVE BW RTJ RF FLANGE 150LB 300LB 600LB 1500LB 2500LB

Gold top 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.

  Other remarks 1	The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve.
  Other remarks 2	SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing
  Other remarks 3	Rising stem structure, making the valve switch position be clear at a glance
  Other remarks 4	The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced.
  Other remarks 5	Small switching moment, reliable sealing
  Other remarks 6	The gate valve is of wedge and resilient type that can compensate the slight deformation, so the sealing performance is good.
  Other remarks 7	Small flow resistance, high flow capacity and good flow characteristics
  Other remarks 8	For small gate valves, the interchangeability can be ensured with process tooling.
  Other remarks 9	Through improving the structural design and selecting reasonable packing structure and qualified packing supplier, the valves can meet the Class A sealing test requirements of ISO 15848 FE.
