    Why does the valve on my Bray Controller pop out of the seat and slam open?
    • D
      Diane WongJul 27, 2025
      If the valve in your Bray Controller pops out of its seat and slams open, it might be because the valve torque is too high, the actuator is too small, or the air supply flow is insufficient. You can repair the valve, use a properly sized actuator, and ensure you have larger air supply lines or a solenoid valve with higher flow.

      If there is binding between the valve and actuator in your Bray Controller, the cause may be misalignment of the coupling. To fix this, realign the coupling.

      If your Bray Controller loses power, this could be due to low air supply pressure or damaged O-rings. To resolve this, try boosting the air supply pressure, repairing any leaks in the air supply line, or replacing the O-rings.
