Test bench for shut off valves DN 50...300 mm (2...12″)

Purpose

  • shell test acc. to API 598, API 6D, ISO 5208 etc.;
  • seat leakage test (cavities A to B, B to A) acc. to API 598, API 6D, ISO 5208 etc.;
  • backseat test acc. to API 598, API 6D, ISO 5208 etc.;
  • DBB/DIB test acc. to API 598, API 6D;
  • control valve seat leakage test, acc. to ANSI FCI 70.2, IEC 60534-4, EN 1349 etc.


Tested valves

  • gate valves;
  • ball valves;
  • stop valves (globe valves);
  • check valves;
  • butterfly gates;
  • plug valves;
  • control valves.

Connection type

  • flanged RF, FF, RTJ (according to ASME B 16.5, ASME 16.47 etc.);
  • BW (according to ASME B 16.25, etc.);
  • Flangeless (lug, wafer type).

  • Adjustable valve testing position: valves intended to operate vertically are tested vertically, valves intended to use horizontally are tested horizontally;
  • Quicker valve mounting and centering because of three simultaneously moved claws
  • No airtraps during filling, the valve is filled vertically and then tilted to horizontal position
  • Possibility to observe sealing surface during leakage test (45 degrees tilted valve)
  • Clamping of tested valve is provided by hydraulic cylinder. Optionally test bench can be equipped with proportional clamping control system, which excludes axial compression applied to the valve body during clamping by hydraulic cylinder, during high pressure testing.
  • Two-sided gate sealing during tests does not require the tested valve rearrangement, which significantly reduces the test time.
  • The bench is equipped with the water-collection tray.
  • Test preparation time is significantly reduced by using the high-pressure fast coupling hoses.
  • The bench is quickly adjusted to face-to-face dimensions of valve by using the electrically driven cross-head.
  • All water-wetted parts are corrosion-proof.
  • Increased-diameter hoses reduce the time of the valve filling with the test medium.
