  If your Bray/VAAS Control Unit valve jerks during opening and closing, several factors could be responsible. First, ensure that the superstructure fasteners are properly tightened. For pneumatic operated valves, verify that there is sufficient air supply and increase the supply pressure if needed. Additionally, check for dust accumulation in the solenoid valve and clean it if necessary. Finally, inspect the piston rod seal for damage and replace it if needed.

Why is there high torque during valve seating and unseating in my Bray/VAAS Control Unit?

  High torque during valve seating and unseating in a Bray/VAAS Control Unit can be attributed to a couple of issues. One potential cause is misalignment between the gate and stem. To resolve this: 1. Remove the clevis fasteners. 2. Loosen the superstructure fasteners. 3. Adjust the alignment of the stem and gate. 4. Connect the clevis fasteners. 5. Retighten superstructure fasteners. Another possible cause is that the packing is not tightened properly. In this case, adjust the gland nuts.

  If you're unable to close or open the gate on your Bray/VAAS Control Unit, the gate may be bent. Check the valve orientation, flow direction, and flow indication. Re-orient the valve if necessary. If the gate is indeed bent, replace it.

  If the valve leaks in the fully closed position in your Bray/VAAS Control Unit, it could be due to a worn out or torn seat, in which case you should replace the seat. Alternatively, the gate might be scratched, requiring you to replace the gate.
