About Us

The company began in 1972 as North American Valve & Lapping and was initially involved in repairing compressor valves, a service that we still provide. By 1980, we expanded our activities to other industrial equipment and had begun developing relationships with manufacturers as their authorized representative and repair facility. In 1984, North American Engineering was created to provide on-site services. In 1995, Alliance-North American was created as a “VR” certified pressure relief valve repair facility, distributor, and manufacturers’ representative.

In 2004 we added Farris Engineering, BS & B Safety Systems, & Protego to our product lineup. Our new product sales focuses on pressure relief devices and systems. We are able to service the complete life cycle of our customer's pressure relief systems from initial design, evaluation of exisiting systems, supply of new relief devices and repair existing devices.

NAMW is located in Folcroft, 5 miles from Philadelphia. Our location allows to provide our services and products in the Mid-Atlantic Region from New York, New Jersey, Delaware, Eastern Pennsylvania, Maryland, DC and further.
