The structure is more compact, the size is short, the volume is small, the water loss is low and the noise is low. Under the economic flow rate, the normal working water loss is 1.3-2.5m.

The accuracy and discharge pressure of the drain valve are adjustable, so that it is less disturbed by pipeline pressure fluctuation, safe and reliable opening and closing, and there is no abnormal drainage.

The single diaphragm design and the proven reliability of key components such as diaphragm make its quality superior to the ordinary low resistance backflow preventer.

The unique flow channel design of the two-stage check valve has small flow resistance and fast opening and closing speed, which can effectively prevent the damage of the valve and pipeline caused by the sudden rise of back pressure, limit the backflow of pressure water or siphon backflow, and has the mute function to effectively prolong the service life of the valve.

Humanized design, products can be installed horizontally or vertically, online testing and online maintenance.
