RB70KIT – Automatic Diluent Valve (ADV)

Fitted in place of the inhale T-piece – the ADV supplies gas to the breathing circuit whenever a substantial negative pressure is experienced within the inhale counterlung or when manually operated by pressing the diaphragm cover.

The gas supply hose connects with a 3/8″ UNF thread to the low pressure port (7 to 11 bar) of a first stage or into the diluent port of the rebreather manifold. At the other end it connects to the ADV’s 300 degree swivel with a standard 9/16″ UNF female regulator connector.

The ADV valve is an upstream tilt valve that requires no adjustment or free-flow cut-off device.

The 300 degree swivel gives you the option of feeding the hose from the front e.g. from a suitable side-mounted diluent cylinder.

The ADV is not a pressure relief valve like a normal downstream 2nd stage. It is an upstream design which prevents free-flow into the breathing circuit in the event of a leaking 1st stage seat.

The ADV comes with a C Spanner and an ADV Hose (AP300/15 15″ – Can be shortened, if required).

Other ADV hoses e.g. AP300/38 (38″/97cm for First Stage connection) are available on request. Please call our customer service team on 603-960-0524
