Overview
The VTCON Grooved NRS Gate Valve (VT-GV-GR-NRS-200) is a 200 PSI ductile iron gate valve for water-based fire protection systems.
It uses a resilient wedge design with an EPDM sealing surface to support reliable shut-off and a straight-through waterway. The non-rising stem design provides compact operation and is suitable for fire water piping installations.
This website model corresponds to catalogue model Z85. Use the verified dimension table from catalogue P32 and confirm certification coverage before order.
