Product Overview
The polymer lining and exposed seals need compatibility review for the actual fluid mixture and cleaning conditions. Single-seat control duty also requires trim sizing and a specified shutoff criterion. No particular lining polymer, actuator action or electrical accessory is implied unless identified in the quotation.
Selection and Ordering Notes
- Specify fluid composition, concentrations, flow cases and pressure-temperature conditions.
- Request the exact lining material, wetted-component schedule and complete assembly rating.
- Confirm the Class 150 connection, facing, dimensions and applicable project standards.
- Identify the air supply, control and feedback interfaces and required operating and failure behavior.

Frequently Asked Questions
Does Class150 establish this lined valve's allowable pressure at my temperature?
Request the pressure-temperature limits for the quoted valve with its actual lining, seals and other components. Provide the operating and design conditions; the class designation alone is not a complete rating for the lined assembly.
Which fluoroplastic will be supplied in the single-seat valve?
Ask for the selected lining material and wetted-component specification in the quotation. The current fluoroplastic description does not confirm a particular polymer or make different lining materials interchangeable.
What information should I provide for a lined single-seat control-valve quotation?
Send the complete fluid composition, concentrations, flow cases, inlet and outlet conditions and connection requirements. Include the available air and control-system requirements and request the selected trim, actuator and accessory documentation.
