In this video, you can find our Pres-Vac authorized engineer demonstrating how to check the PV Valve opening setting. Ship crew can follow the listed steps below onboard their vessels for PV valve maintenance.

  1. Set the value of the pressure gauge to 0
  2. Turn the switch to the pressure side to allow air supply 
  3. Check and compare the reading on the pressure gauge with that on the PV valve itself 
  4. Turn the switch to the vacuum side
  5. Check opening value of valve opening 

*Please contact us if the deviation between readings is more than 10%
