Product Overview

The FIVC Gate Valve is designed for dependable full-flow isolation in potable water systems. Its straight-through design ensures minimal pressure loss, while the robust ductile iron construction delivers long-term durability and tight shut-off performance. The rising stem design also provides clear visual confirmation of valve position while keeping critical threads outside the flow for improved reliability.
