Open Atmospheric Vents are installed on the top of vent pipes from underground or above ground 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. These vents are always open to atmosphere and allow any pressure or vacuum in the tank to vent. The OPW 23 Series is a perfect choice for many applications.

• Reliable Service – Vent cap drain spouts extend outward to deter rainwater entry.
• Corrosion-Resistant Construction – Aluminum body and cap assure a long service life.
• Easy Installation – The 23 is available in 2" and 3" slip-on models that provide for attachment to the vent line with set screws.
• Complies with NFPA 30 Requirements – For venting gasoline vapors upward.
• High-Maximum Flow Rate – 7,000 SCFH at 2 psi (0.14 bar) pressure drop.
• 40-Mesh Brass Wire Screen – Helps prevent debris and insects from entering the tank vent lines.

244O--0600AVEVR
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.

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.
