Backflow preventer Socla CA2096 DN 15x21

This chamber is closed by a shutter linked to the upstream valve.

In the event of negative pressure upstream of the device or excess pressure downstream with a leak at the second valve, the intermediate chamber is vented to atmosphere, thus separating the upstream and downstream circuits and preventing any backflow of polluted water.

The CA 2096 non controllable reduced pressure zone backflow preventer is designed for the protection of installations with intermittent risks that nevertheless require a backflow preventer: domestic heating installations of less than 70 Kw, automatic beverage dispensers, certain laboratory equipment, etc...

A minimum clearance of 150 mm shall be provided around the wrapped volume of the device (except on the face side) and the relief valve shall not be submerged.

- the device must be mounted in a horizontal position

- the device must be easily accessible

- it should not be installed in flood-prone areas

- it must be installed in a ventilated environment (unpolluted atmosphere)

- the drain must be able to accommodate the discharge flow

- it must be protected against frost or extreme temperatures.
