Flanged gate valve F4 DN80 with soft seal, short without handwheel, PN10, GJL-grey cast iron 60.851.080.111

Flanged gate valve for water – reliable flow shut-off

The DN80 flanged gate valve, made of grey cast iron, is a robust solution for shutting off flow in water supply networks and installations, designed for potable water and non-aggressive liquids. Its short design without a handwheel makes it easy to install and ideal for areas with limited space. This valve is suitable for both underground and above-ground installations.

Design and application

The valve is designed for durability and reliability. The body made of grey cast iron (EN-GJL-250 according to PN-EN 1561:2000) provides corrosion and mechanical damage resistance. The vulcanized NBR/EPDM wedge guarantees tightness, and the replaceable O-rings on the stem (the “DRY THREAD” system) allow for seal replacement without shutting off the flow. A straight bore without a socket minimizes flow resistance. The valve meets the requirements of PN-EN 1074-1,2:2002 and PN-EN 1092-2:1999 regarding flanged connections.

Key features and benefits

• Durability and resistance: Made of high-quality grey cast iron, resistant to corrosion and mechanical damage.
• Tightness: Vulcanized wedge and the “DRY THREAD” sealing system ensure reliable sealing.
• Easy maintenance: Replaceable O-rings allow for seal replacement without disassembling the valve and shutting off the flow.
• Safety: Withstand voltage of min. 3 kV at 250 μm provides protection against short-circuit effects.
• Versatility: Designed for potable water and non-aggressive liquids, ideal for water supply, sanitary and industrial installations.
• Wide temperature range: Can be used with EPDM seals (up to +110°C) or NBR seals (up to +70°C), adapting to different working conditions.
• Simple installation: Flanged design with 8 mounting holes (diameter 19 mm) facilitates installation.
• Efficiency: Maximum water velocity up to 3 m/s ensures efficient flow.

This valve is a proven choice for both professional installers and end-users looking for a reliable solution to shut off water flow in their installations.
