EPV 6500 vent
Features
• A selection of vents for specific applications
• Intrinsically safe operation
• Continuous flow vents for precise flow rates for dilution
applications
• Continuous flow outputs for dilution, purging, and
pressurization
• Low leakage rate vents for air or inert gas conversation
• High flow rate vents for fast, large enclosure systems
• Universal mounting in any orientation including most of the
unit inside the enclosure
• Maximum enclosure size 12.75 cu.meters (450 cu.ft.)
• ATEX/IECEx, Zone 1/21 certified for "pyb" and "pxb"
• Up to SIL 2 acc. to IEC 61508
Application
The 6500 system consists of the 6500 control unit, EPV-6500
pressure relief and monitoring vent, and a valve for
pressurization, purging, and with some models dilution for
analyzer applications. The EPV-6500 vents are available in
different configurations for specific or general applications.
The housings are the same but the flows and pressures are
different for specific applications. The continuous flow vent
allows for precise flow rate measurements that allows for
dilution applications in gas analyzers that is dealing with any
hazardous gas. Safe flow rates are user-selectable through
the 6500 control unit for safe operation and control of the
6500-MAN-PV (proportional valve). The EPV-6500 vents can
be mounted in any orientation and the body can be mounted
inside the pressurized enclosure with just the vent cap outside
for clean, un-intrusive look. The EPV-6500-SS-* model
includes reference pressure tubing and hardware for internal
mount. The EPV-6500 vent is intrinsically safe when used with
the 6500 control unit. No I.S. barrier is required with the 6500
control unit.

Note: These graphs should only be used for representation of flow and pressure through each type of vent and not used for
calculating purge time. They can be used for estimating purge time but the actual purge time will be automatically calculated by
the 6500 control unit. These graphs are used to determine which vent type will be best suited for the application.
