The VAG KFS Gate Valve is a durable, metallic-sealed valve engineered for highly demanding wastewater and industrial environments. Renowned for its minimal-maintenance design, the valve features zinc-free bronze seat rings and stem nuts for longevity. Available in multiple configurations tailored to diverse installation needs—such as rising or non-rising stems, manual or electric operation, and gearbox options for large diameters.
Rising Stem: DN 50–1200 Non-Rising Stem: DN 300–1200
Standard PN 10/16 suitable for heavy-duty applications

EN 558 Basic Series 14 (flat type)
Rising stem (outside thread); Non‑rising stem (inside thread)
Stainless Steel 1.4057
Withstands up to 90% vacuum
• Municipal wastewater systems
• Industrial effluent and sewage pipelines
• Pressure and flow isolation systems in harsh environments
• Buried or elevated installations depending on stem choice
Designed to handle raw water, cooling water, municipal wastewater, weak acids, alkaline media, and oil-contaminated flows.
• Rising Stem – Handwheel
• Rising Stem – Electric Actuator
• Non-Rising Stem – Handwheel
• Non-Rising Stem – Electric Actuator
Robust, maintenance-minimal design for polluted or abrasive media
• Rising stem offers visual position indication; non-rising is compact for confined spaces
• Low internal friction with long-term sealing integrity
• Compatible with manual or automated control systems
• High vacuum resistance and custom options (e.g., burial kits, actuators, gearboxes)
• Gearbox or electric actuator (especially for DN 400, 700, 1200)
• Drain plug and stuffing box design for easy maintenance
• Stem extension or lantern enclosure kits for buried installations
• Specialized coatings or seal upgrades for corrosive environments
From forging and casting to machining, assembly, and testing — every step is managed under one roof to ensure consistent quality, faster lead times, and zero compromise.
