Common Questions
- What is the maximum working pressure?
- This unit is built as 150# Flanged and is rated to 175 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 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 for fire protection?
- Yes — this model carries the UL listing 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.
