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 ensure optimal system performance, safety, and reliability, it’s critical to ensure the right size valve is used. Proper valve sizing allows for reduced costs, less downtime, and fewer labor needs — keeping operations running smoothly and efficiently.
Below are some key points to keep in mind when sizing control valves.
