The OCV2 was designed to improve O2 injection into a CCR reliably and offer easy control for O2 injection
and flow control. Some divers do not dive electronic control systems due to failures. Orifice type
injection systems are subject to failure due to clogging. They require inline filters and an external shut
off valve. The OCV1 requires no filters, offers easy adjustment of flow requirements, and flow shutoff is
built in by the rugged seat design. The internal piston is double o-ring sealed. The seat design offers
easy blow out if trash enters the valve.
Standard needle valve and some orifice flow systems only adjust flow relative to the 1st stage constant
pressure. The OCV2 uses the same constant pressure 1st stage(160psig), but also uses the water pressure to
fine tune the flow from the valve and truly meet the optimal flow requirements. The adjust knob has
incremental positions for fine tuning. Flow is adjustable from 0 to over 3 liters per minute (LPM). Each
position represents approximately .12 liters of flow per minute giving the diver the ability to fine tune
the flow.
The OCV2 offers both manual and adjustable flow control in a small user friendly package. The over all
body dimensions are 3.25 x 3.25 x 1.0 inches. The OCV2 body is machined from a solid piece of Delrin for light
weight. All internal and external components are stainless steel or plated brass, replaceable, and designed for long use.
The unit weighs less than 2 pounds and will fit on any standard webbing. The input and output ports are a
standard 1/4 NPT to give the diver multiple options for installation. The OCV2 comes with standard BC
inflator connectors for easy set-up and emergency disconnect.
The OCV2 has been 3 years in development and testing. It has been on test dives to depths over 300 feet,
and on four different types of CCRs.
Here are a summary of the Key Reasons For the Valve
- Alternative to electronic oxygen controller on CCR
- Alternative to standard needle valve and orifice injection valves
- Alternative to manual add systems
- Better gas management efficiency
- Compact auto and manual controls
- Increased diver safety
- Better reliability
- Redundant and built in shut-off capabilities
- No inline filters required
- Ergonomical and small designed unit
