The 2 inch LFM1116 150 flanged angle pressure relief, sustaining or backpressure control valve is designed to permit flow when upstream pressure is above the adjustable setpoint of the control pilot, and throttle toward closed when upstream pressure falls below the adjustable setpoint.
Features
- Class 150 flanged
- 250 psig rated
- Maintains flow based on upstream pressure
- 20-200 psig
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.
