    Why is my Bardiani Control Unit difficult to open and close?
    • E
      Eric HarrisAug 11, 2025
      If your Bardiani Control Unit is difficult to open and close, several factors could be responsible: * The elastomer used for the gaskets might be incorrect, in which case, replace it with a gasket made of a different type of elastomer. * The actuator may be positioned incorrectly; ensure it is installed correctly. * The actuator's operation could be flawed; try switching from Normally Closed (NC) to Normally Open (NA) or vice versa. * There might be impurities present in the actuator; conduct an inspection and perform necessary maintenance. * The valve body might be positioned incorrectly; disassemble and reposition it correctly.
