Gulbransen Valves
By Bob and Sonja Lemon
Valve travel of 1/32" or .032 should be more than sufficient for a Gulbransen valve. It sounds like you have replaced the existing wooden valve buttons with a much thinner material. It is difficult to re-leather original valve buttons and not require paper spacers. You may have to add leather to the buttons to reduce the travel. Excessive travel leads to excessive air usage and makes for a noisy operation. Be sure to check for proper seating of the valve buttons as we explained in an earlier posting.
