Armstrong serves across many industrial sectors with a wide range of products.

DFT® has been making the in-line check valves for over 70 years. It started with a customer’s need for a small metal-seated check valve that could be installed in any position while providing tight shut-off. The Basic-Check® valve was developed to satisfy that need.

After years of research and performance evaluation under severe throttling services, where precise computer control was required, Flowserve Worcester Controls has developed the CPT characterized seat control valve series. These valves exceed the performance features of traditional linear valves, as well as that of segmented ball and eccentric plug designs.

Worcester Controls is a division of Flowserve dating back to 1959 and is the leading manufacturer of valves and actuators. They supply a wide series of valves ranging from three piece ball valves to modulating control valves. Worcester supplies flanged ball valves and both ANSI and DIN specifications in full and reduced bore. They have valves for almost any application such as multi way designs, high purity, steam, high pressure, diverter or sampling duty, and cryogenic.
