Introduction

Scope of the Manual

This Instruction Manual provides instructions for

installation, maintenance and parts ordering guide for

the ES-800 and ES-900 Series vent valves.

Product Description

ES-800 and ES-900 Series vent valves represent the

latest development in high-performance, tight-sealing tank

venting products, and complement Enardo’s industry-

leading ES-600 Series thief hatch product line. With a

leakage rate of no more than 1 SCFH at 90% of set point,

the ES-800 and ES-900 Series o󰀨ers unparalleled vent

valve performance.

Model ES-800-SO – is an In-line vent valve. It is

installed directly into the vent line exhaust. The

Model ES-800-SO has both pressure and vacuum

relief capability.

ES 8 20 PSO

Model ES-800-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-800-SO

pressure/vacuum except they omit the vacuum side of

the valve that eliminates the possibility of two way ow.

Model ES-900-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-900-SO has both

pressure and vacuum relief capability.

Model ES-900-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-900-PSO only

has pressure relief capability.

Principle of Operation

ES-800 and ES-900 Series vent valves are designed

to prevent the escape of light ends of crude by

maintaining presssure in the storage tank.

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 orice and relieving the pressure

or vacuum buildup. The valve closes once the tank

pressure goes below the set pressure.

water after handling. Keep away from

excessive heat and open ames.

Specications

The Specications section on this page provides specications for the ES-800 and ES-900 Series vent valves.

Specications 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.

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.

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.

WARNING

ES-800 Series In-Line 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.

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 tighten the wing-nuts on

both sides. Check for proper alignment between

the lid and pallet stem. If the pallet is not installed

correctly, the lid would not close.

ES-900 Series End-of-Line 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 (up).

WARNING

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

tighten the wing-nut. If the pallet is not installed

correctly, the hood would not close.

Maintenance

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.

Do not use greases or oils on guide

rods. These will not allow the vacuum

assembly to work properly.

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.

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.

North America Only

WARNING

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.

V-ring Replacement

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.

1. Remove the pallet assembly. Grasp the pressure

seal rmly by the lip and pull out.

2. Insert the new seal. Use a nger, wrench or other

smooth edge to apply a rm pressure while sliding

around the entire seal several times. When the

seal is completely seated, there will be no humps

or waves in the lip.
