DIN Flanged Gate Valve F4 Ductile Iron

The DIN flanged F4 ductile iron gate valve is designed for isolation in compatible marine and industrial piping systems. Its ductile iron body provides mechanical strength and toughness, while the F4 short-pattern face-to-face arrangement offers a compact installation length for new piping layouts and replacement projects. The gate moves perpendicular to the flow direction and retracts from the main passage when fully open, providing relatively low flow resistance. DIN flanged connections allow installation in matching piping systems and facilitate removal during maintenance.
Potential applications include freshwater distribution, cooling-water circuits, shipboard auxiliary services, water treatment facilities and industrial utility lines. Seawater and lubricating-oil applications require suitable internal materials, sealing components and corrosion protection.
Intended primarily for fully open or fully closed operation, the valve provides a practical means of isolating equipment or pipeline sections for operation and servicing; continuous throttling should be avoided to reduce vibration and wear on the gate and seating surfaces.
