Pressure Vacuum Vents are installed on the top of vent pipes from underground or above- <br />ground fuel storage tanks. The vent cap and internal wire screen are designed to protect <br />the tank vent lines against intrusion and blockage from water, debris or insects. A normally <br />closed poppet in the valve opens at a predetermined pressure or vacuum setting to allow <br />the tank to vent. <br />OPW 623V Pressure Vacuum Vent Features: <br />+ Pressure/Vacuum Setting - <br />3" water column pressure settings and <br />8" water column vacuum settings are <br />factory preset and tested, <br />+ Reliable Service - Cycle tested to the <br />equivalent of 80 years of service in the <br />most severe environment without <br />leakage problems. <br />+ Corrosion-Resisterd Construction -A <br />DuratufP° composite body assures a <br />long service life. <br />+ Easy Installation - The 623V is available <br />in 2" and 3" threaded versions, <br />+ California Air Resources Board <br />Certified <br />+ EVR-Certified <br />+ Underwriters�L <br />Laboratory Listed <br />+ Complies with NFPA 30 <br />Requirements - for venting gasoline <br />vapors upward, <br />+ High Maximum Flow Rate - 6450 <br />SCFH at 2 psi pressure drop. <br />+ Manifold Vent Pipes - Vent pipes may <br />be manifolded to produce a single <br />Pressure Vacuum Vent line. The 623V <br />exceeds Calffomia's requirements of a <br />maximum vapor leak rate of 0.17 SCFH <br />at 2.00 inches Hao <br />♦ Leak Rate - Multiple pressure vacuum <br />vents may be installed on a single site. <br />The 623V exceeds California standards <br />with a leak rate of 0.05 SCFH or less at <br />2.00 inches HO, <br />♦ Maintenance - No tools required. A <br />removable snap fit top allows for easy <br />maintenance (recommended yearly). <br />+ 100 -Mesh Stainless Steel Wire <br />Screens - Helps prevent debris and <br />insects from entering the tank vent <br />lines. An added screen installed at the <br />base prevents debris from intruding <br />from the vent stack, <br />+ Adaptor Bushing - Removable Hex <br />threaded bushing designed for easy <br />installation on NPT threaded risers. <br />Allows easy access to lower screen. <br />Conversion Table o <br />Meayumment In HyO In H9 4:NNT8P3Ep: <br />UNLt = Ot P51 C Mere Ber <br />236.0 10.5 1 401.6 1 29.53 <br />In. e x 7.949 0.48 13.y _0;034 Patent No. W020041036DVAZ <br />In 1 all ivc) z 0,579 0,04 m7A 0,002 <br />PSI Y 16:00 27:56 2:04 0.069 <br />On. z I 1 623 L 1.73 0.118 om4 <br />Replacement Pates Ordering Specifications <br />Pan Number <br />Description <br />cosmem <br />Lawar Seven <br />H1459514 <br />._.,... <br />Upper Screen <br />C05959 _— <br />2" nveaded Base Adaptor <br />CD5122 <br />3"7hreaded Baer Adapbr <br />C05102M <br />wrench for Paly.
