Product Description
The YS-BD is our 316 stainless steel Y strainer with a blowdown valve: instead of the standard blow-off plug, a quarter-turn ball valve sits on the drain port. Open it for a moment and line pressure flushes the trapped debris straight out through the drain — no wrench, no opening the cap, and filtration continues the second you close it.
The strainer body is rated 800 WOG with a SUS 316 screen in 20, 60 or 100 mesh (20 mesh is the standard we ship). Female PT threads are in stock, sizes 1/4″ to 3″; NPT and PF can be made to order. Prefer the simple plug version? See the standard 316 Y strainer, or browse the Y strainer category.

Application Fields & Locations
- Lines flushed on a schedule: where debris builds up fast and stopping to unscrew a plug is not practical.
- Pump protection: on the suction side, with quick purging of trapped debris before it accumulates.
- Water treatment: pre-filtration ahead of meters and instrumentation with regular blowdown.
- Chemical & process lines: keeping debris out of downstream equipment between maintenance windows.
FAQ
How is this different from a standard Y strainer? The body and screen are the same — the difference is the drain. A standard Y strainer has a threaded blow-off plug you remove with a wrench; the YS-BD has a quarter-turn ball valve there instead, so you can flush the screen by hand in seconds. See the standard Y strainer for the plug version.
Can I flush the strainer without opening the cap? Yes — that is the point of the blowdown valve. Open it briefly and line pressure pushes the trapped debris out through the drain; close it and filtration continues. The cap only needs to come off for screen inspection or replacement.
Which mesh should I choose — 20, 60 or 100? 20 mesh is the coarse, general-purpose screen and the default we ship. 60 mesh catches finer sediment ahead of meters and nozzles. 100 mesh is for fine particles ahead of control valves and instrumentation. All three are in stock.
Which thread standards are available? Female PT threads are in stock, sizes 1/4″–3″. NPT and PF can be made to order — tell us which standard your piping uses when you request a quote.
Where can I find the dimensions? The strainer body shares its dimensions with our standard Y strainer — download the Y-Strainer dimension sheet (PDF) from the card at the top of this page for the full assembly drawing and measurements.
