The dimensions above are in increasing order for the umbrella skirt diameter. Combination valves are inserted into a flat, smooth surface with at least 20% of the diameter as clearance around the outside of the skirt to allow flow. The mounting plate should have a thickness which matches the relieved area at the base of the duckbill. The hole into which the duckbill barrel is inserted must have a small clearance so it can flex as needed.
