In-Line Valve Testing (AVK Tester)

What is AVK?
The AVK is an in-line pressure relief valve testing device (commonly referred to as an ALD, Auxiliary Lift Device). Its primary function is to verify set pressure of pressure relief valves in-line. The AVK requires stable system pressure to perform testing.
How does testing work?
Using the data acquired through system transducers, the AVK consistently and accurately verifies valve set pressure. The portable device includes a small actuator assembly that is mounted to the valve. A custom-designed adapter with sensor applies force to the valve spindle to determine set pressure. The test results can then be printed or downloaded to other applications.
Benefits of AVK UltraLite Testing Device on a Pressure Relief Valve:
  • Eliminates costly and time-consuming valve removal
  • Valve testing conducted while system is active and boiler stays on-line
  • Valves failing AVK can be scheduled for repair
  • Steam cuts and leaks are rare since the AVK does not take the valve into full lift
  • Repairs and testing using this device are recognized by National Board and customer’s insurance inspectors
