Matco-Norca has upgraded its lead free brass 759 Press Ball Valve (759PLF) to feature leak-prior-to-press technology. This design incorporates a special EPDM O-ring that allows water or air past the sealing element of any un-pressed connection. Growing industry use of press-fit technology has had a major influence on pipe joining systems in the United States in recent years. Press-fit systems offer the advantage of flame free installations, making solder connections a less preferred method in copper applications. Not only does the press-fit system make the jobsite safer by eliminating the risk of fire, it also lends itself to greater productivity and reduced labor costs.
The press-fit feature is built into the design of the ball valve’s O-ring and provides a path for liquids from inside the pipe to weep past the sealing O-ring of an un-pressed connection. Manufactured in ISO 9002 approved factories and available in sizes 1/2- up to 4-inch, Matco-Norca’s upgraded 759PLF Ball Valves come with one O-ring and are compliant with UPC, AB1953, NSF-61 and NSF-372 standards.
