OVERVIEW: The Model YIFN is a ductile‑iron, flat‑face Class 150 Y (wye) strainer certified to NSF/ANSI 61 & 372 for potable‑water service. Available in 2"–12" diameters, it safeguards pumps, meters, valves, and instrumentation in municipal and commercial water systems by intercepting debris before it can foul downstream equipment. The heavy‑wall ASTM A536 65‑45‑12 body is factory‑coated inside and out with a high‑build white epoxy for superior corrosion resistance and immediate identification as potable‑water equipment. Rated 250 psi WOG @ 100 °F and hydro‑tested to 300 psi, the YIFN combines rugged construction with low pressure loss and easy maintenance. Options include fine‑mesh or non‑NSF screens, factory‑installed blow‑down valves, gauge‑tap bosses, and PN16 drilling.
Stayflow’s new YIFN extends our proven Y‑strainer line into certified potable‑water applications—delivering reliable protection where water quality and public health standards are paramount.
FEATURES
- NSF/ANSI 61 & 372 CERTIFIED – Approved for U.S. & Canadian potable‑water systems.
- Large screen‑to‑pipe open area minimizes pressure drop, modeled after Stayflow’s YCF series.
- Robust ductile‑iron body & cover for long service life in demanding installations.
- 304 SS perforated screen welded along the seam for maximum strength and longevity.
- Self‑cleaning capability – NPT blow‑off port (½"–2") with plug; add a drain valve for in‑line flushing.
- Gauge‑tap bosses (optional) allow differential‑pressure monitoring to signal when cleaning is required.
- Durable white epoxy finish distinguishes potable‑water service components.
