Overview
The VTCON Grooved OS&Y Gate Valve (VT-GV-GR-OSY-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 outside screw and yoke design provides visible stem movement for clear valve position indication.
This website model corresponds to catalogue model Z81. Use the verified dimension table from catalogue P29 and confirm certification coverage before order.
