What to do if Gemu Control Unit valve leaks downstream?

  If your Gemu Control Unit valve leaks downstream and doesn't close fully, it could be due to several reasons. The operating pressure might be too high; ensure it matches the data sheet specifications. Foreign matter could be lodged between the shut-off seal and seat; disassemble the actuator, remove any debris, and inspect the shut-off seal for damage, replacing it if needed. The valve body itself could be leaky or damaged, requiring inspection and potential replacement. A faulty shut-off seal can also cause leaks, so check it for damage and replace if necessary. Finally, a faulty actuator spring could be the culprit, necessitating actuator replacement.

Why Gemu 514 Control Unit valve doesn't open fully?

  Jennifer ClarkAug 17, 2025
  If your Gemu Control Unit valve isn't opening fully, several factors could be responsible. First, the control pressure might be too low; adjust it according to the data sheet and inspect/replace the pilot valve if needed. Ensure the control medium is properly connected. A leaky control piston or spindle sealing could also be the cause; in this case, replace the actuator and check the control medium for impurities. Lastly, check if the stroke limiter is incorrectly adjusted and correct it if necessary.

  If your Gemu Control Unit valve leaks between the actuator and the valve body, the issue could stem from a loose union nut. Try tightening it. Alternatively, the gasket might be faulty. Inspect the gasket and the respective sealing surfaces for damage, replacing parts as needed.
