Overview
The VTCON Flanged OS&Y Gate Valve (VT-GV-FL-OSY-300) is a 300 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 Z41-300. Use the verified dimension table from catalogue P19 and confirm certification coverage before order.
