Advantages

  • High precision and visibility when testing for gate tightness with air. 
  • A large range of measured leakage allows testing of control valves with tightness class II-VI as per (ANSI / FCI 70-2). 
  • Unit allows to connect additional flow sensors to register the leakages by using computer registration system CRS.* 
  • Mobile design of the unit allows to move it between the different benches, depending on the need for testing of control valves. 
  • Built-in filter eliminates the need to clean the flowmeters in contact with foreign particles from the tested valves.
