01
Define the service
Medium, pressure, temperature, line size, duty cycle and installation constraints determine the usable valve range.
02
Confirm the construction
Compare body style, seat or trim, end connection, actuation, fire-safe or fugitive-emission requirements and maintenance access.
03
Freeze the project records
The approved datasheet, drawing, ITP and document index control the final quotation and manufacturing release.
