Reviews

As always. Aircraft Spruce to the rescue! The valve was exactly correct, and works perfectly. Best of all it was delivered early. Keep up the good work!

This unit does not hold pressure. No I have to drain out 5606 and remove part to exchange for another. Hopefully that one will hold pressure.

Q: Which port goes to the hydraulic reservoir and which port goes to the brake, or does it matter?

Port A, horizontal port is the supply, and port B, vertical port is the out flow.
