Gate Valves

RAC can supply pressure seal and bolted bonnet gate valves.
RAC pressure seal gate valves are designed, manufactured and inspected in
accordance with the International Standards, namely: ASME, MSS, API, etc.
The pressure seal joint eliminates the body and bonnet flanges reducing
weight and simplifying the application of exterior insulation.
Contrary to bolted bonnet valves, internal pressure applied to a pressure
seal valve forces the sealing elements into tighter.

MAIN ADVANTAGES

  • Universal use for temperature up to 649°C
  • Fluid tightness achieved by fluid pressure, not from mechanical action thus eliminating thermal binding
  • Ideal for processes with large temperature variation
  • Perfect tight shut-off in either directions
  • Self-aligning fully supported discs
  • Flexibility compensates for seat face distortion
  • Inherent self-cleaning action
