Nautilus Over Pressure Valve
The DIR Zone over pressure valve is designed to be attached to any first stage that does not have a means of venting gas if it were to fail.
The main use for the DIRZone OPV is attachment to a drysuit inflation first stage to provide slow and safe release of gas if the first stage were to fail. Simple, compact and reliable and OPV is an absolute must on any drysuit inflation first stage.
The DIR Zone over pressure valve is made using a 3/8" thread for fitting to most first stages.
