Products - Automatic Machine 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. Today, Automatic Machine continues to produce the highest quality shut-off and service valves in the refrigeration and air conditioning industry, UL rated to 700 psig. Our product offerings have expanded over that time to include adapters, brass valves and various companion parts. Today AMP provides product to leading original equipment manufacturers on six continents. We are committed to the quality, development, expansion, and diversification required in meeting our customers’ expectations.
