Product Overview:

Single Diaphragm Low Resistance Backflow PreventerHS BXFM-10Q /P is a hydraulic control combination device used in urban water supply units and general pollution units to strictly limit pipeline pressure, allowing water to flow only in one direction. Its function is to prevent medium backflow or siphon backflow under any working condition, thereby achieving the purpose of avoiding backflow contamination.

Product Features:

1. More compact structure, shorter dimensions, smaller volume, low backflow, low noise, and normal working water loss of 1.3-2.5 meters at economic flow rates.

2. The accuracy and drainage pressure of the drain valve are adjustable, minimizing interference from pipeline pressure fluctuations, ensuring safe and reliable opening and closing without abnormal drainage.

3. Single diaphragm design, with proven reliability of key components such as the diaphragm, making its quality superior to ordinary low-resistance backflow preventers.

4. Unique flow channel design of the two-stage check valve, with low flow resistance and fast opening and closing, effectively preventing damage to the valve and pipeline from sudden backpressure increases, limiting pressure water backflow or siphon backflow, featuring silent operation and effectively extending valve service life.

5. User-friendly design, allowing horizontal or vertical installation, online testing, and online maintenance.
