ALLEN AIRCRAFT PRODUCTS, INC.
Allen Aircraft was a vision in the eye of Neil Mann, Sr. While working at Wright Airfield in Dayton after World War II, Neil had the idea for a more efficient drop-tank valve to be used on the government’s long-range military aircraft.

Check Valves
Allen Aircraft Products, Inc.
Check Valves are spring and/or gravity loaded to the closed position to control backflow through the system. Housed check valves tuned to a wide range of cracking pressure/pressure drop requirements are available along with independent check elements for incorporation in customer equipment.
Self Closing Valves
Allen Aircraft Products, Inc.
Self-closing valves offer a practical, economical solution to fluid loss problems in applications requiring more frequent inspection of magnetic plugs or chip detectors. Available in threaded or bayonet designs, the valves close down automatically as the magnetic plug or chip detector is removed. This eliminates the loss of expensive lubricants and reduces the need to clean up after inspection. As a result, inspection is faster and more convenient for maintenance personnel.
Both types of self-closing valves offer maximum exposure of the magnet to the flow of lubricant or hydraulic fluid. The wide-open design is essential to proper functioning. If the free flow is restricted, ferrous chips and particles are less likely to come in contact with the magnet.
Self-closing valves are sealed with “O” rings, providing a positive seal under the low-pressure condition generally associated with their application. The “O” rings seal the valve when the plug is in position and when it is removed for inspection.

About
Allen Aircraft was a vision in the eye of Neil Mann, Sr. While working at Wright Airfield in Dayton after World War II, Neil had the idea for a more efficient drop-tank valve to be used on the government’s long-range military aircraft.
Returning to his hometown of Ravenna, he set up shop in the corner office of a friend, George Walter. With the aid of another friend, Hugh Riddle, Neil was able to design and manufacture his valve. To raise capital for future ventures and ideas, Neil and Hugh organized Allen Aircraft Products, Inc. (named in memory of Douglas Allen Mann) and sold 80 shares of stock to investors in the Ravenna community.
Our first order was from Boeing for a drop tank disconnect valve for use on the B-50 Bomber which was an upgrade of the B-29. Over the years Boeing has continued to be our largest customer with parts on all Boeing Commercial Aircraft since the 707, as well as on all military aircraft including the B-50.
In 1949, the development and manufacture of a new line of valves and the addition of a patented solid film lubricant, which was the beginning of our Metal Finishing Division, caused Allen to move into a 1,200 square foot facility at Cotton Corners. The building was formerly the Vicker Trailer Agency on the corner of Woodbine Avenue and Newton Falls Road. In 1952, Allen doubled its size by the construction of an office addition. By this time, the company had developed more than 50 different products for the aircraft industry. In addition to the drop tank valve, the line had grown to pressure relief valves for hydraulic systems, drain valves for fuel tanks, oxygen couplers for unpressurized cabins, landing gear, and other hydraulic actuators.
By 1962, Allen Aircraft expanded its operations for the fifth time at this location by constructing a new 6,000 square foot building onto the existing one at Newton Falls Road. Along with this expansion, Allen’s ranks had grown to 60 employees. Also, at this time Allen had become the world’s only manufacturer of the automatic fuel transfer jet pump. During the war, pilots had to manually throw a switch in the cockpit to activate an electric motor driven pump to transfer fuel from one tank to another. With the development of this new pump, aircraft could become lighter, more reliable, and less expensive.
Throughout the 1990’s Allen continued to invest in the latest CNC machines, and quick-change tooling. The combination of some of the latest technology in CNC machines along with quick change tooling and cellular techniques have made our machine shop one of the most capable in the area.
In 1997, and again in 2001, Allen Aircraft completed major acquisitions that included the aerospace product line of The Lisle Corporation located in Clarinda, Iowa and Dyna-Air Corporation, a division of Shaw Aerospace located in Naples Florida. The product lines included chip detectors, magnetic plugs, and oil level sensors.
The acquisitions provided access to engine and gearbox manufacturers throughout the aerospace industry. Our company is now a recognized industry leader in the design and development for these products.
Today, Allen Aircraft enjoys long term relationships with nearly every major engine and airframe manufacturer in the world. These relationships secure our long-term interests in the aircraft community and forms the basis of our commitment for continuous improvement in all the things we do.
