Victaulic gate valves feature three internal parts making maintenance simple. The disc
is rubber encapsulated for true compression sealing and the reduction of wear and
jamming. The Series 771H OS&Y and Series 771F OS&Y gate valves are used when
positive shut off is required and a quick visual indicator of open/closed position is
required. The Series 772H NRS and Series 772F NRS gate valves are typically used for
shut-off service where the valve is operated remotely, such as when the valve is behind
a wall or buried. Series 772H NRS and Series 772F NRS gate valves are offered with
optional wall (Series 773) or upright (Series 774) post indicators.
