Frequently Asked Questions
Does Class 150 mean this gate valve has a fixed working pressure of 150 psi?
No. Class 150 is a pressure-class designation, not a universal working-pressure value. Provide the actual design pressure, temperature and selected materials and confirm the applicable pressure-temperature rating for the ordered valve.
Should I specify RF or RTJ flange faces for my installation?
The page refers to RF and RTJ flange-face options. Specify the facing required by the mating piping, gasket arrangement and project specification, and confirm the selected valve drawing before ordering. Do not assume that different facings can be substituted without review.
How do I choose between the listed WCB, CF8 and CF8M body options?
Provide the process medium, operating temperature and pressure, and the project material requirements. Confirm the body and wetted trim together for the selected order. The material list does not mean that every option is suitable for the same service.
