Kerotest purchased the bar stock needle valve product line from Marsh Instrument Company  in 2000.  The carbon steel and stainless steel 10000 PSI Hard Seat Needle Valves as well as the 6000 PSI Soft Seat models are now manufactured in Mansura, Lousiana.  This bar stock product augments the forged and cast steel offering that Kerotest has manufactured for almost 100 years.  The designs and specifications are  identical to the Marsh Instrument product that we have sold successfully for 30 years.
