What to do if Burkert AirLINE 8644 Control Systems valves do not switch?
- R
  Robert WilsonAug 2, 2025
  If Burkert Control Systems valves aren't switching, check the electrical connection to ensure adequate operating voltage according to the type plate. Also, make sure the manual actuation is in the neutral position. Inadequate pressure supply could also be the cause, so design the pressure supply with the largest possible volume, ensuring a minimum operating pressure of 2.5 bar.

Why do Burkert Control Systems valves switch with a delay?
- S
  Stanley SmithAug 7, 2025
  If Burkert Control Systems valves switch with a delay or blow off at the deaeration connections, it could be due to several reasons. First, ensure an adequate pressure supply with a minimum operating pressure of 2.5 bar. Pressurize the valve block before switching the valves. Check that the silencers aren't too small or dirty, causing back pressures; clean or replace them with appropriately sized silencers or expansion tanks. Finally, impurities in the pilot or main valve can cause issues, in that case, change the valve.

  If Burkert Control Systems valve blocks are leaking, determine if there are missing or crushed O-rings between the modules, or missing or incorrectly positioned profile seals between the valve and pneumatic base module. Insert any missing seals or replace damaged seals.

Why Burkert Measuring Instruments valves do not switch?
- K
  Kevin WalshAug 17, 2025
  The Burkert Measuring Instruments valves may not switch due to several reasons: * There might be no operating voltage or the voltage is too low. In this case, check the electrical connection and ensure the operating voltage matches the type label. * The manual override might not be in the neutral position. Return the manual override to the zero position. * The pressure supply might be insufficient or unavailable. Maximize the pressure supply, ensuring a minimum operating pressure of 2.5 bar, also check upstream devices.

  Joel HoustonAug 22, 2025
  If Burkert Measuring Instruments valves switch with a delay, consider the following: * Ensure the pressure supply is sufficient and available. Maximize the pressure supply, checking upstream devices and ensuring a minimum operating pressure of 2.5 bar. * Make sure the valves are in the home position (de-energised) during pressure build-up. Pressurize the valve block before switching the valves. * Check for insufficient ventilation of exhaust air ducts due to small or dirty silencers. Use appropriately sized silencers or expansion vessels and clean any dirty silencers. * Impurities or foreign matter in the pilot or main valve can cause delays. Replace the valve.

  If you have leaky valve blocks in Burkert Measuring Instruments, it might be due to missing or crushed O-rings between the modules, or missing/incorrectly positioned profile seals between the valve and pneumatic base module. Try to identify leaks or missing seals. Insert missing seals or replace damaged seals.
