2"NPT, <br /> E Q <br /> The OPW 53-V Series Float Vent Valves are designed C <br /> to be installed in OPW 233-V Series extractor fittings to ° <br /> form a system to help prevent underground tank <br /> overfill,and reduce product mixing. <br /> The OPW 53-V Series Float Vent Valves have a - <br /> stainless steel ball which seats tightly against a specially " <br /> designed valve seat,cutting off the flow of vapors to the <br /> Stage I vapor recovery system,or the tank vent.These <br /> valves are superior to other valves because of the <br /> stainless steel ball float and specially designed <br /> Duragard'" coated seat which helps eliminate valve <br /> hang up due to corrosion. <br /> OPW•Floal Vent Valves ale <br /> Covered Under Patent No.3.736.950Model 53-VM shown1 <br /> 2"Diameter B <br /> Ball <br /> Product No. A B C D E Weight <br /> 53-VM and Suffix (Dimensions In inches) Lbs. <br /> Used as an integral part of the OPW overfill system to 53-VM-0060 101 3',6 3 1/16 61/6 11/2 2.16 <br /> slow down the flow of liquid into the storage tank,and (Calibrated) <br /> provide an overfill warning to the operator. <br /> 53-VML <br /> Same as 53-VM but 12"D dimension,for double 53-VML-0120 1611/16 3 '/16 12 1 1/2 3.99 <br /> wall tanks. <br /> 53-VSS (Calibrated) <br /> Used to minimize product mixing when vent lines 53-VSS-0065 913/,6 3 1/e 51/e 11/2 1.80 <br /> are manifoided underground. <br /> 53-VTS <br /> Similar to 53-VSS except vent bleed hole is only 1/16" 53-VSS-0070 973/t6 3 1/16 51/6 11/2 1.90 <br /> 53-FC <br /> Used only on vapor return line, has no bleed hole. 53-FC-0046 777/.-12 3 NONE 35/32 N/A 1.23 <br /> SIZE: 4" x 2" WT.: 15.33 lbs. 233-V-4420 233-VP-6046 WT.: .78 lbs. <br /> 233-VMP-6047 WT.: 1.24lbs. <br /> The OPW 233-VM extractor is a multi-outlet extractor, 233V 233VM 233VM <br /> available in 2 sizes; used in direct manifoided systems, 4420 4422 6045 <br /> vapor recovery, or where provision for Stage II Vapor <br /> (Tee) (Cross) (Cross) <br /> Recovery is needed. <br /> SIZES:4" x 2" x 3" WT. 18.73 lbs. 233-VM-6045 Top Thread 4" 4" 4" <br /> 4" x 2" x 2" WT. 16.62 lbs. 233-VM-4422 Outlet Thread 2" 2" 2" I <br /> All OPW 233-V series extractors are specially coated with <br /> black Duragard'" coating, for improved corrosion Tank Connec- <br /> resistance and easier cage removal. tion Thread 4" 4" 4" <br />
