Capabilities:

 ♦ Range DN10 2200 mm. / ¼ - 86.
 ♦ Horizontal (stem vertical), vertical. (Stem horizontal) or tilting clamping
  system
 ♦ Clamping on the inlet flange, either flanges or (proportional clamping)
  between the clamping tables.
 ♦ 1 2000 tons of clamping force.
 ♦ With no or limited linear force on the valve body.
 ♦ Test pressure range: from vacuum up to 2000 bar / 30,000 PSI.
 ♦ Test medium: Liquid, compressed air, Nitrogen, Helium or Hydrogen.
 
Standard Features:

 ♦ Computer registration system.
 ♦ Full automatic operation system.
 ♦ Testing one or a complete series of valves.
 ♦ Automatic open close action.
 ♦ Valve performance testing, considering; measuring of the stroke measuring, open/close time and torque measuring.
 ♦ Stainless tubing.
 ♦ Fugitive emission and cryogenic test facilities on requirement.


Tests include:

√ Shell test - pressure inside the assembled valve to 1.5 times working pressure.
√ Back seat test - pressure inside with seat fully opened and closed to 1. 1 times working pressure.
√ High pressure closure test -pressure applied to each side of the closed valve to 1. 1 times working pressure.
√ Low pressure closure test - same as high pressure but with air at 100 psi (7 bar), detected by air bubbles in a water column or in
   laser bubble counter.
√ Relief valve test - opening pressure using a ’Pop’ test and to 90-95% of set pressure.
