Introduction
Scope of the Manual
This Instruction Manual provides instructions for installation
and maintenance for the 2000A Series Emergency Pressure
Relief Vent (EPRV).
Product Description
Emergency pressure relief vents are designed to provide an
emergency pressure relief opening for storage tanks when
exposed to overpressures that are not handled by standard
tank vents.
The 2000A Series Emergency Pressure Relief Vent (EPRV)
provides pressure relief only. Properly-sized 2000A Series
meet the API standard 2000 for emergency venting due to
re exposure. This vents provide quick easy access for tank
inspection and maintenance.

Hazardous Locations
Emergency Pressure Relief Vents are available with outer
housings of carbon steel, stainless steel or aluminum as
indicated in Figure 3.
Nameplate
A nameplate is attached to the vent and contains the
following information:
• Model Number – Ex. 2024A-21T-1
• Connection Flange Size – 24 in.
• Serial Number
• Tag Number (Optional)
•Notied Body Number – Ex. 2460
• Cat. No. (Category Number)
- Category 1 – Stainless steel, Carbon steel or Coated
aluminum vents
- Category 2 – uncoated aluminum vents
• Date – date of manufacture
•Certicate – Ex. PRESAFE 17 ATEX 10273X
• Pressure Setting and Flow Rate
-Setting – Ex. Z4.0
-Flow Rate SCFH (Air) – Ex. 00000
Remote Monitoring Option
The Smart Wireless monitoring option is available with the
2000A Series. It allows the detection of the Open or Closed
position of the emergency vent from a remote site. Under
normal conditions, the emergency vent should be Closed. An
Open indication can alert personnel that there is a potential
safety or emissions issue that should be further investigated.

Figure 6. Pressure Flow
Principle of Operation (Figure 6)
The 2000A Series maintain a tight seal until system pressure
exceeds the set pressure of the vent. To adjust the set
pressure, a series of weights may be stacked onto the lid
assembly. When overpressure occurs, the weighted lid
assembly lifts, breaking the seal between the seat and
seal portion of the lid assembly. This allows vapors to pass
through the vent orice and relieve pressure build up. The
vent reseals upon relief and remains sealed.
Note
Relieving vapors near the set pressure in
a continuous manner may cause the lid
assembly to utter or oscillate. This is a
common occurrence in products of this type
in the industry. Operating the vent with utter
or oscillation over time may cause premature
vent damage or wear. Contact your local
Sales O󰀩ce for additional assistance.
Remote Monitoring Option
The Smart Wireless option for the 2000A Series consists of
the EPRV, a proximity sensor, and a wireless transmitter.
The built-in proximity sensor detects the open or closed
position using a magnetic target located on the arm
assembly on the hinged end. A signal is sent to the wireless
transmitter, which can then be sent to a control room via any
WirelessHART®Gateway. This wireless sensor networking
technology is based on the Highly Addressable Remote
Transducer (HART®) protocol. It is the most widely used
wireless networking standard used today and, for this
reason, the 2000A Series has been designed to integrate
with it. As long as the wireless gateway is WirelessHART®, it
will receive the Open or Closed signal from the device. The
WirelessHART®gateway will then send the information to a
control room which can make use of any number of software
integration packages.
HART®and WirelessHART®are marks owned by FieldComm Group.

▲WARNING
Wear protective gloves and clothing to prevent
skin contact when handling lead weights. Wear
eye protection. Avoid breathing dust/fumes/
mist/vapors/spray. Do not eat, drink or smoke
while using the product. Avoid release to the
environment. Wash hands with soap and water
after handling. Keep away from excessive heat
and open ames.
Make sure line is free of hazardous vapors
before installing or servicing the valve.
The EPRV Series is shipped with its lid held
partially open. The lid assembly has attached
weights and is heavy. Use caution when
removing the shipping blocks and metal bands
to avoid injury to ngers and hands.
Before installing the relief vent, remove the unit from its crate
and discard any protective coverings. Follow the instruction
below for the installation of the 2000A Series.
Install the 2000A Series on the ange bolt patterns that
match with bolt pattern of the vent. The attachment ange
base should be at level surface.
1. Carefully remove the 2000A Series from its crate. The
seal portion of the vents is delicate, protect this surface
while handling the unit.
2. Place the appropriate gasket on the level attachment ange
and center the vent into place.
3. Insert the appropriate number of bolts and make sure the
vent is fastened securely. Installed bolts should be clear of
the lid assembly when it is in the full open position.
4. Inspect the installed unit from items that would keep it
from working properly. The sealing area should be free of
any debris that would cause leakage. The arm of the vent
should be able to fully open.

CLOSE
Maintenance
▲WARNING
Always make sure that the tank is at
atmospheric pressure before opening.
pressure build-up inside the tank can cause
a spray to be emitted from the vent if opened
under pressure.
An opened EPRV, where the EPRV arm and
cover have rotated away from contacting the
base, contains a large amount of potential
energy. Always use appropriate lifting
equipment when installing or maintaining the
EPRV to avoid the risk of serious injury if the
EPRV closes rapidly.
Follow the instruction below for the preventive maintenance
of the 2000A Series.
1. Rotate arm. Inspect and make sure the open and close
without block.
2. Inspect seat and seal whether they are damaged. Clear
away any debris or buildup that may cause the vent
to become lodged or impede air ow through the unit.
Clean the internal components with a suitable solvent
and non-abrasive cloth.
3. Close the arm slowly. Inspect the close without block.
4. Clear away any debris or buildup on the unit surface
that may cause the vent to become lodged, impede air
ow or add weight to the lid assembly (added weight will
adjust the pressure setting of the vent).
Remote Monitoring Maintenance
1. Maintain 2000A Series EPRV with Smart
Wireless Monitoring option in the same way as all
standard EPRV.
2. Take certain precautions when cleaning the transmitter.
The surface resistivity of the antenna assembly is
greater than 1 GΩ. To avoid electrostatic charge
build-up, it must not be rubbed or cleaned with solvents
or dry cloth.
Pressure Setting Information
The 2000A Series can reach various pressure settings in
units of ounces, inches of water, millimeter of water, or kPa
column. The minimum pressure setting that each vent can
achieve depends on the individual vent size and material.
Minimum settings are reached when the unit is installed by
itself. However, when weights are added to the arm of the
unit, elevated pressures can be reached. These elevated
settings are preset at the factory and should never be
eld adjusted.
