The American National Standards Institute (ANSI) sets rules and guidelines regarding the most critical technical aspects of various components manufactured for industrial use in North America. All ANSI-compliant Baelz valves are also compliant with ISA specifications. This is due to the International Society of Automation’s (ISA) reaffirmation of existing ISA valve-related standards, which include ANSI valve standards.
To meet clients’ specific application needs, we keep a wide variety of ANSI valve sizes in stock and available for immediate purchase in 150# and 300# pressure classes. Larger valves and some additional sizes are available through special order.
