BW2 Shuttle-type flow switches are intended for reliable flow and no-flow monitoring in liquid systems operating at medium to high flow conditions.
Available models support adjustable actuation ranges from 0.5 GPM up to 100 GPM, covering a wide range of application requirements.
The switch bodies are built with durable, industrial-grade housings and are offered with process connections from 3/4" NPT through 3" NPT.
An optimized internal flow channel design minimizes pressure loss, maintaining efficient system performance even at maximum flow rates.
Fixed Set Point: Pre-calibrated for precise flow detection.
High Accuracy: ±1% maximum deviation in set point repeatability.
Wide Flow Range: 0.5 to 100 GPM across multiple port sizes.
Robust Construction: Bronze or 316 stainless steel housing, Teflon® shuttle, 316 stainless steel spring.
Low Pressure Drop: Straight-through flow path design.
Broad Operating Temperature: –30°C to +150°C
