Series VNR, SCS & VSC Valves - Poppet Design
Check, Shuttle, and Quick-Exhaust Valves |
|
|
** All Series 3 valves are equipped with
flat geometric ring seals in the packed
bore construction, (A wider flat edged
portion of the seal ring seals against the
external packing spacers and valve inner
body, while a thinner rounded lip seals
against the spool surface). The design
offers significantly improved sealing over
traditional o-rings or oval rings, especially
between differing surface geometries,
such as spools and packing glands. |
** All Series 4 valves are equipped with dual seals in the packed bore construction, (O-rings
around external packing glands, and dual lip " airzet" seals around the spool body for
improved performance in both vacuum and more rigorous media sealing situations). |
** All Series 7 valves offer a balanced packed-spool design. This design permits a
customized seal geometry to be fitted onto the spool directly. Benefits are less vulnerability
to "varnishing" and/or contamination due to smaller seal contact area with the
valve bore. Maintenance is reduced due to less parts and labor required to repair, while
providing increased seal life and leak-free performance. |
