Product Description

WARNING: USE OF THIS DEVICE ON ANY LIFE SUPPORT EQUIPMENT IS EXTREMELY DANGEROUS AND COULD CAUSE INJURY OR DEATH WITHOUT WARNING.

WARNING: The OV2 valve must have a constant supply pressure to maintain a constant mass flow output. Use of a pressure compensating supply gas valve will cause changes in output flow rate.

The OV2 is an oxygen compatible control valve that uses an orifice to control flow and has a manual injection add button. The valve can be purchased with one of three different flow orifices and several different porting options. A 50 Micron filter screen is installed inside the inlet ports.   All orifices also have a filter.  Available orifice diameters are .0025, .003, or .0035 inch. Maximum allowable inlet pressure is 175 psig.  The OV2 valve is the same as the OV1 valve except there is an additional inlet port for offboard hookup.

The OV2-5 valve shown above has Swagelok quick connect (QC4) female fittings at the inboard inlet and outlet ports. The offboard port is the 2nd inlet port and has a standard 3/8-24 female thread.  Use of the female QC fittings requires the mating QC male connectors. Both male and female QC connectors have shut-off valves built in the fitting. This allows for emergency disconnection and connection options underwater with minimal water infiltration in and out of the valve. ATTN: THESE QC FITTINGS DO NOT SUPPLY SUFFICIENT GAS FLOW FOR OPEN CIRCUIT BAILOUT! NEVER USE A QC4 FITTING TO SUPPLY GAS TO A 2nd STAGE REGULATOR! A QC6 fitting is required for sufficient open circuit flow requirements.

The OV2-5 with a .0035 flow orifice is part number OV2-5-0035. This part number includes two male QC connectors and fittings to attach the male connectors to the 9/16-18 threaded end of a standard LP scuba regulator hose. The OV2-5-0035 is often used on ECCRs as a safety backup and to reduce electronic injection requirements. The flow rate of the OV2-5-0035 with an inlet pressure of 160 psig is approximately (.030 CFM or .85 LPM).

SAFETY RECOMMENDATIONS:

A 300 psig rated over pressure relief valve should be installed on the supply gas valve to help to prevent overpressuring the OV90 valve. Overpressurizing of the valve can cause excessive flow or failure.

An inline shutoff valve should be installed between the supply gas valve and the OV2 valve.
