Auta 050FH DN80 (3") Ductile Iron Hydraulic Float Control Valve PN10/PN16 with Stainless Steel Float (Epoxy Coated / Flanged Connection)

Auta 050FH DN80 (3") Hydraulic Float Level Control Valve:

• Technical Specifications: Nominal size DN80 (3" / 80mm), working pressure PN10 / PN16, ductile cast iron body with electrostatic fusion-bonded epoxy coating, stainless steel 304 pilot float ball, multi-standard flanged connection (PN10/16, JIS, ANSI 150), operating temperature 0-80°C.
• Power-Free Hydraulic Self-Actuation: Uses pipeline hydrodynamic pressure driven by pilot float movement to open/close main diaphragm automatically without electrical power.
• Drip-Tight Positive Sealing: High-resilience EPDM/NBR reinforced diaphragm ensures zero leakage and prevents reservoir overflowing or water hammer.
• Fusion-Bonded Epoxy Protection: Heavy internal and external epoxy coat protects ductile iron from clean water rust and chemical leaching.
• Applications: Municipal water storage reservoirs, high-rise building rooftop tanks, commercial industrial plant water supply, and fire reserve tanks.
