• Petroleum, non-combustible hydraulic fluids, feed water for boilers, condensate.
• Drinking water
• Sea water.
PERFORMANCE
• AISI 316 stainless steel disc.
• Cuff – rubber EPDM or NBR, (on request FPM/FKM).
• Other materials on request.
**OPTIONS**

• Electric or pneumatic drive.
The Double Flange Butterfly Valve DIN PN 10 is engineered for high-performance flow control in demanding industrial applications. Constructed to meet DIN standards with a pressure rating of PN 10, this valve ensures reliable shut-off and regulation of liquids, gases, and semi-solids. Its robust design features a double flanged connection for secure installation and easy integration into piping systems, minimizing leakage risks and enhancing operational safety. Ideal for water treatment, chemical processing, HVAC, and general industrial use, this valve offers durability and efficiency in a compact form.Key specifications include a disc that rotates 90 degrees for quick operation, a resilient seat for tight sealing, and compatibility with various actuation methods (manual, electric, or pneumatic). The valve body is typically made from materials such as ductile iron, stainless steel, or other alloys, providing corrosion resistance and long service life even in harsh environments. It supports temperatures up to 120°C and is designed for easy maintenance, reducing downtime and total cost of ownership.Double flanged ends conform to DIN standards for secure mountingPressure rating: PN 10 (10 bar)Suitable for water, air, chemicals, and mild abrasive fluidsAvailable in sizes from DN 50 to DN 600Optional materials and actuation packages to meet specific needs
