Common Questions

What fluid temperature can the Buna-N trim handle?

This valve is built with Buna-N elastomers, good to about 160°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 UL Listed and FM Approved for fire protection?

Yes — this model carries the UL listing and FM approval required for fire-protection service. Non-listed control valves cannot be substituted on a fire job even when the body and pilot are otherwise identical.
