Common Questions
- What is the maximum working pressure?
- This unit is built as 150# Flanged and is rated to 600 psi. End connection sets the ceiling on this platform, and 150# and 300# bodies are not interchangeable — confirm the class matches your flange drilling before ordering.
- What fluid temperature can the EPDM trim handle?
- This valve is built with EPDM elastomers, good to about 300°F. Watts offers the same body with Buna-N (to 160°F), FKM/Viton (to 250°F) or EPDM (to 300°F) — pick the elastomer for your fluid temperature, not the body.
- Is this valve certified lead-free for potable water?
- Yes. The "LF" prefix denotes Watts lead-free construction, compliant with the weighted-average 0.25% lead requirement of the Safe Drinking Water Act (NSF/ANSI 372) for potable-water service.
