523A-1003
Pressure Vacuum Vents are installed on the top of vent pipes from underground or aboveground fuel storage tanks. The vent cap and internal wire screen are designed to protect the tank vent lines against intrusion and blockage from water, debris or insects. A normally closed poppet in the valve opens at a predetermined pressure or vacuum setting to allow the tank to vent.

• A Variety of Pressure/Vacuum Settings – 3" water column, 1 oz., 8 oz., 12 oz. pressure settings and 8" water column or 1/2 oz. vacuum settings are factory preset and tested.
• Reliable Service – A self-guided poppet assembly ensures consistent seating of the pressure/vacuum valve.
• Corrosion-Resistant Construction – Duratuff® composite body assures a long service life.
• Easy Installation – The 523V is available in 2" and 3" threaded versions or slip-on models that provide for attachment to the vent line with allen head screws and radial sealing "O-ring".
•Complies with NFPA 30 Requirements – For venting gasoline vapors upward.
• High Maximum Flow Rate – 7,000 scfh at 2 psi pressure drop.
• 40-Mesh Stainless Steel Wire Screen – Helps prevent debris and insects from entering the tank vent lines.

244OF-0050 AV
Emergency vents are installed on aboveground storage tanks as a code requirement. Emergency vents provide high capacity pressure relief if the tank is exposed to fire. When the internal tank pressure reaches the opening pressure of the vent, the weighted cover moves up on the center pin allowing air to escape. When the internal tank pressure falls, the cover automatically lowers back onto the body and is automatically reset.

The 244 emergency vent is for "emergency pressure relief only" and must be used in conjunction with a "normal vent" or pressure vacuum vent. The 244 emergency vent must be properly sized and selected for each specific tank application in order to meet the proper "venting capacity" requirements.

9095X-2200 AV
The 9095X is a top-fill overfill prevention valve designed to prevent overfilling storage tanks by providing a positive shut-off during a pressurized fill.

• Fill adapter and shut-off mechanism are factory-assembled for ease of field installation
• Straight female threaded adapter facilitates valve installation to a precise set point
• Minimum shut-off height is 1” from the tank top
• Full flow to shut-off point, cushioned closure eliminates shock

A0084-038
The Emco Wheaton A0084 is an internal pressure vacuum valve that restricts vapor escape during product drops. Typically installs on the top of the vent pipes from the underground or aboveground fuel storage tanks. The vent valve is equipped with a wire mesh screen designed to protect the storage tank vents against intrusion and blockage from rain water and debris. A normally closed poppet within the valve opens to allow the tank to vent (see chart below). The body and cap are anodized aluminum for corrosion-free service.
