Functions of test bench for flow tests (according to PN-EN 126 standard):

• Determination of Kvs coefficient.
• Calculation of relative flow to relative opening characteristic Qx/Q100=f(Hx/H100).
• Determination of flow resistance coefficient based on relative opening characteristic ζ=f(Hx/H100).
• Measurement of pressure drop and flow rate for full open valve position.
• Automatic data reporting.

Main applications:

• Regulating valves,
• Shut off valves,
• Throttle valves,
• Y-strainer filters,
• Gate valves.

Advantages include:

• A wide range of possible fittings can be tested with our test bench:
  • Easy assembly with flanged valves produced according to PN-EN 1092-1 and PN-
    EN 1092-2 (PN), PN-EN 1759-1 (ANSI) and ANSI / ASME B16.5,
  • Easy assembly with weld-on ends of valves for butt-welding according to DIN3239 (PN) and ASME 36.10 M (ANSI).
• A possibility to test fittings of various lengths.
• A storage for testing and connecting fittings.
• Manual and automatic valves are supported.
• An advanced control system:
• Visualizations of measured data with graphs,
• Guidance messages for the operator during the whole test,
• A possibility to create new test program or edit existing ones,
• A storage of data points on USB drive,
• Generating reports from tests in PDF files on PC connected to the test bench with
  help of Ethernet network (proprietary software).
