VALVE

a division of Olson Technologies, Inc.

Mosser Valve is located in the Heart of the Lehigh Valley in Allentown, PA. In the same location for over 138 years, Mosser is dedicated to its customers and employees alike. As others have moved out of the Allentown area, Mosser Valve is a proud Pennsylvania manufacturer and dedicated to staying here.

Our main offices are located at the corner of Walnut and 2nd St. Our main office holds our production, purchasing, accounting and engineering departments. Our sales department and executives are located at the corner of 119 S. 2nd St. and Union St. 

Mosser's Plant #1 encompasses the entire block of Walnut/Union/2nd St. Our 110,000 sq. ft. Plant #2, where all of our manufacturing now takes place, is located two blocks away on Linden St. across from the future site of the much touted "Lehigh Landing". Our #1 plant is now used for production and testing or our large diameter AWWA butterfly valves and space is rented to other local manufacturers who require more space or use of our 20 ton crane.

History: Since 1862
