properly install and maintain this equipment
could result in an explosion, re and/or
chemical contamination causing property
damage and personal injury or death.
Enardo™ vent valves must be installed,
operated and maintained in accordance
with federal, state and local codes, rules
and regulations and Emerson Process
Management Regulator Technologies
Tulsa, LLC instructions.
Failure to correct trouble could result in a
hazardous condition. Call a qualied service
person to service the unit. Installation,
operation and maintenance procedures
performed by unqualied person may result
in improper adjustment and unsafe operation.
Either condition may result in equipment
damage or personal injury. Only a qualied
person shall install or service the vent valves.
Introduction

WARNING
!
The ES-805 and ES-905 Series vent valves is
not necessarily grounded when installed on
berglass reinforced plastic tanks unless the
base is electrically bonded to the tank.
To avoid personal injury or property damage
resulting from the effects of a static electricity
discharge from hatch components in a
hazardous atmosphere or where the process
uid is combustible, electrically bond the base
to the tank with grounding strap.

Specications
The Specications section on this page provides specications for the ES-805 and ES-905 Series vent valves. Specications
such as model number, connection size, date of manufacture, valve type, seal materials and pressure/vacuum settings are
stamped on the nameplate attached to the vent valve. Weights are keyed to the pallet stem. Every weight is stamped with the
setting (oz.), the valve size and the part number.

Product Description
ES-805 and ES-905 Series vent valves represent the latest
development in high-performance, tight-sealing tank venting
products and complement Enardo™’s industry-leading
ES-665 Series thief hatch product line. With a leakage
rate of no more than 0.1 SCFH at 90% of set point, the
ES-805 and ES-905 Series offers unparalleled vent
valve performance.
Model ES-805-SO - is an In-line vent valve. It is installed
directly into the vent line exhaust. The Model ES-805-SO
has both pressure and vacuum relief capability.
Model ES-805-PSO - is a pressure only vent valve designed
to relieve pressure only through the vent line. It is designed
the same as the Model ES-805-SO pressure/vacuum except
they omit the vacuum side of the valve that eliminates the
possibility of two way ow.
Model ES-905-SO - is an end-of-line vent valve. The
end-of-line vent valve is installed directly on the end of the
vent line exhaust. The Model ES-905-SO has both pressure
and vacuum relief capability.
Model ES-905-PSO - is an end-of-line vent valve. The
end-of-line vent valve is installed directly on the end of the
vent line exhaust. The Model ES-905-PSO only has pressure
relief capability.
Principle of Operation
ES-805 and ES-905 Series vent valves are designed to
prevent the escape of light ends of crude by maintaining
pressure in the storage tank.
Approximate Weight
ES-805 Series Vent Valve
2 In. / 50 mm body: 12 lbs. / 5 kg
3 In. / 80 mm body: 17 lbs. / 8 kg
4 In. / 100 mm body: 23 lbs. / 10 kg
ES-905 Series Vent Valve
2 In. / 50 mm body: 11 lbs. / 5 kg
3 In. / 80 mm body: 15 lbs. / 7 kg
4 In. / 100 mm body: 19 lbs. / 9 kg
The vent valve opens when the system pressure or vacuum
exceeds the set pressure of the valve. When over pressure
occurs, the pallet lifts, breaking the seal between the seat
and pallet, allowing vapors to pass through the valve orice
and relieving the pressure or vacuum buildup. The valve
closes once the tank pressure goes below the set pressure.

Tagging Information
For ES-805 Series, the nameplate is located on the unit’s lid
and for ES-905 Series, the nameplate is located on the unit’s
hood. Actual layout of nameplate may vary.
Installation
The valve and its pallet assembly are shipped
separately. The pallet assembly may be heavy
and can cause personal injury or damage to the
unit if not handled with care.
All wing-nuts shall be hand tightened only.
Tools are not to be used.
Prior to installation, remove the unit from its packaging
and discard any protective coverings. Below is a list of
instructions that are recommended for the installation of an
Enardo vent valve.

1. Unbolt and remove the anges from the body.
2. Slide the ange onto the receiving pipe. Then slide the
slip-on gasket onto the pipe. The tapered section of the
gasket points away from the ange and towards the
valve. Repeat on the other pipe using the second ange.

1. Unbolt and remove the anges from the body.
3. Reinstall the ange bolts and nuts, one on each side.
Tighten bolts until anges are ushed against the body.
4. Install the pallet assembly. The center rib of the pallet
should be in-line with the rib on the body. Then close the
lid and hand tighten the wing-nuts on both sides. Tools
are not to be used to tighten wing-nuts. Check for proper
alignment between the lid and pallet stem. If the pallet is
not installed correctly, the lid would not close.
2. Slide the ange onto the receiving pipe. Then slide the
slip-on gasket onto the pipe. The tapered section of the
gasket points away from the ange and towards the
valve (up).

3. Reinstall the ange bolts and nuts, one on each side of
the ange. Tighten bolts until ange is ushed against
the body.

4. Install the pallet assembly. The notch in the center
rib of the pallet should be in-line with the front guide
rod. Check for proper alignment between the lid and
pallet stem. Then close the hood and hand tighten the
wing-nut. Tools are not to be used to tighten wing-nuts.
If the pallet is not installed correctly, the hood would
not close.
Maintenance
ES-805 and ES-905 Series
1. Remove the pallet assembly from the valve. Pull the
vacuum disk down until it stops and release it. If the
vacuum disk does not return to the closed position,
clean the rods with a mild solvent and apply a graphite
lubricant. If cleaning does not x the problem, replace
the pallet assembly immediately.
2. Check the vacuum disk for proper opening. Pull the
vacuum disk down until it stops and then rotate the disk in
both directions. If the vacuum disk does not rotate freely,
replace the pallet assembly immediately.
WARNING
!
Ensure the tank is at atmospheric pressure
before opening. A pressure build-up inside the
tank can cause a spray to be emitted from the
vent valve if opened under pressure.
All wing-nuts shall be hand tightened only.
Tools are not to be used.
Do not use greases or oils on guide rods.
These will not allow the vacuum assembly to
work properly.
Perform a scheduled maintenance every
three (3) months or more often if needed.
Units in corrosive or dusty atmospheres
may require more frequent inspections and
maintenance. Always inspect the pressure and
vacuum gaskets and all sealing surfaces when
performing maintenance.
North America Only
3. Inspect the vacuum gasket. Remove any debris on this
gasket. If there are any tears or holes in the gasket,
replace the pallet assembly immediately.
4. Inspect the pressure seal. Remove any debris on this
seal. If there are any tears or cracks in the seal, replace
the pressure seal immediately.

WARNING
!
Ensure the tank is at atmospheric pressure
before opening. A pressure build-up inside the
tank can cause a spray to be emitted from the
vent valve if opened under pressure.
The legacy ES-800 and ES-900 Series valve can be
upgraded to an ES-805/ES-905 Series by replacing the
existing pallet assembly with the new ES-805/ES-905 Series
pallet assembly.
Retrot kits that include a new ES-805/ES-905 Series pallet
assembly, V-ring seal and nameplate are available. Follow
the instructions outlined in the Maintenance section of this
manual for removal and replacement of pallet assembly and
V-ring seal. Part numbers for ES-805/ES-905 Series retrot
kits can be found in Table 5.
