Our stainless steel NEWCO gate, globe, and check valves offer a complete collection in all grades of stainless steel.
With sizes 1/4 through 24 in [5 through 600 mm], ANSI Classes 150 through 4500, stainless steel NEWCO valves are constructed in accordance with the specifications of American standards organizations with the primary objective of guaranteeing uniformity in production. These standards are universally used in the oil, petrochemical, and chemical industries.
Because of their comprehensive nature, these standards give a clear definition of the product. Standardized production in accordance with these specifications embraces the standards and codes for recommended materials, dimensional requirements, and temperature pressure ratings.
Cryogenic stainless steel NEWCO valves are also available.
