Procedures for installing 71SO valve detailed in new OPW video
Sep 1, 2009 12:00 PM
OPW Fueling Components, a Dover Company, has released an installation video for its OPW 71SO CARB/EVR certified vapor-tight overfill prevention valve. The purpose of the video is to familiarize customers with proper procedures for assembling and installing the OPW 71SO valve.
This video can be downloaded at: www.opw-fc.com by clicking on the “News” link at the top of the page.
The video spells out the assembly and installation instructions for the 71SO, including upper and lower tube assembly, and valve installation. Originally launched in 2007, the OPW 71SO — which has also received Phase I Vapor Recovery System certification from the California Air Resources Board (CARB) — has been designed to prevent the overfill of USTs by providing a positive shut-off of product delivery. Because it requires no epoxy sealants, the 71SO reduces installation time and costs while eliminating the curing hassles associated with hot- and cold-weather installation conditions. This epoxy-free design also provides a higher level of protection against release of fugitive emissions and pressure-decay failures.
The patented design of the 71SO delivers improved enhanced vapor-recovery compliance by eliminating 10 of 17 potential vapor-leak passages. This is achieved through the use of Polypak seals, blind holes with special taptite screws, and a straight threaded joint with a diametric O-ring, all of which remove the need for epoxy sealants during installation.
This video is not intended to replace the OPW installation and maintenance instruction documents provided with each 71SO valve. For complete assembly, installation, and maintenance, refer to OPW Document H15524PA.
