    What to do if the seats are leaking on my Cameron Control Unit?

      Daniel BatesAug 3, 2025
      If the seats of your Cameron Control Unit are leaking, it could be due to several reasons. First, ensure the valve is completely closed. Operate the valve to the fully closed position and then Block-and-Bleed the valve to confirm the leakage has stopped. If the operator stops are incorrectly adjusted, properly adjust them and then Block-and-Bleed the valve. If the seat rings are malfunctioning, clean and flush them.

      If the stem of your Cameron Control Unit is leaking, it might be due to a loose stem screw or nut. Try tightening the stem screw or nut enough to stop the leak, but be careful not to exceed the specified torque value. If the stem seal is damaged, replace it and inject a small amount of sealant into the stem injection fitting.
