RaahSafety Gate Valve

KVC Gate valves are manufactured to API Std.600 and tested to API Std.

Gate Valves are the most commonly used shut-off valve in the industry today. They are used where minimum pressure drop and bi-directional on-off service is required. Gate valves are not designed for throttling service. Prolonged use in the partially open position will generally damage seating surface.

SPECIFICATION

  • Bolted Bonnet
  • Outside Screw and Yoke
  • Flexible Wedge
  • Oval Bonnet with integral Yoge
  • Rising Stem - Non-rising Handwheel
  • Welded-in / Threaded Seat Rings
  • Full Port
  • Raised Face Flanged Ends or Buttwelding Ends Gear Operated recommended for size 14" above

KVC Globe Valves are manufactured to BS1873 And API Std.600, and tested to API Std.598

Globe Valves are used where throttling and shut-off are required. They can also be used for on-off service, but because of high pressure drop, this is generally confined to applications where the valve is normally closed and drop is not important when the valve is open.

Specification

  • Bolted Bonnet
  • Outside Screw and Yoke
  • Yoke integral with bonnet
  • Rising Stem - Handwheel
  • Welded or Threaded Seat Ring - Stellited
  • Full Port
  • Raised Face Flanged Ends or Buttwelding Ends Gear Operated recommended for size 10" above

RaahSafety Swing Check Valves

KVC Swing Check Valves are manufactured to BS1868, API Std.6D and API Std.600, and tested to API Atd.598

Swing chech valves are used to prevent flow reversal in piping system. They are suitable for service in horizontal or vertical (flow up through valve only) piping runs. Swing check valves have low pressure drop and are best suited for moderated velocity applications

Specification

  • Bolted Cover
  • For Horizaontal or Vertical Lines (up Flow Only)
  • Welded or Threaded Seat Ring
  • Full Port
  • Raised Face Flanged Ends or Buttwelding Ends
