What to do if Weir Control Unit experiences loss of pressure?

  If the Weir Control Unit valve does not seal or loses fluid through the discharge, it could be due to several reasons. The valve might not be set properly, so ensure it is correctly set. Alternatively, there could be damage to the main seal assembly, discharge nozzle or wear sleeve, or the high-pressure cylinder connection; in any of these cases, replace the damaged parts. Lastly, contaminants might be trapped between the wear sleeve and nozzle or main seal; if so, clean the affected parts.

  If the Weir Control Unit is shuddering (rapid opening and closing), it is likely because the system pressure is hovering at the set pressure. To fix this, raise the set pressure slightly.

How to prevent rapid erosion in Weir Control Unit?
- S
  Susan MerrittAug 22, 2025
  Rapid erosion in the Weir Control Unit can occur if it's used as a continuous bypass, in which case you should use it only as an emergency unloading device. Another cause is using it beyond its rated capacity; to solve this, install a sufficient quantity of valves to meet capacity requirements.
