500SE Second Stage
Pneumatically balanced servo valve system
Patented Orthodontic Mouthpiece for comfort and reduced jaw fatigue
Standard with 30" maxflex hose
Easily disassembled without the use of tools and underwater if necessary
Left or right positioning - no upside down
Boltsnap tie point
DC7 First Stage
High performance over-balanced first stage provides progressively greater intermediate pressure as depth and gas density increases for superior gas delivery under the most extreme conditions
Fixed hose routing ideal for both backmount and sidemount configuration
Environmental sealing prevents internal corrosion, contaminants, and icing of the first stage
Designed to withstand the rigorous CE standard for coldwater performance
Nitrox compatible to 40%
2 High Pressure and 4 Low Pressure ports
DIN/300 bar
How it works
The 500SE's pneumatically balanced servo-valve is actually a two-stage valve. Just a small sip through the mouthpiece opens the servo mechanism or control valve lever. Air flow from the servo valve creates a vacuum which immediately opens the main valve diaphragm allowing air to flow through the regulator to the mouthpiece. Instead of one small port to provide air flow from the first stage, the 500SE features porting around the entire main valve. With less restriction from the first stage, this allows maximum performance.
