HVAC & Refrigeration Products

Automatic Machine Products was the first to manufacture steel shut-off and service valves. In 1946, Primore, Inc. developed a line of shut-off valves for the air conditioning (HVAC) industry and brought this new line of valves to Automatic Machine Products to manufacture. AMP became the sole manufacturer of the “Primore Line” of valves, working closely with Primore design, engineering, and sales teams for over five decades.
