ANSI/AWWA C502 fire hydrant I5O-NFH series

• NAFFCO Fire Hydrants are designed to comply with ANSI/AWWA C502. • Dry barrel design eliminates damage to the hydrant caused by freezing of the upper part. • NAFFCO Fire Hydrants are designed for high performance and easy to install, maintain and repair. • Excellent and proven flow characteristics. • 2 x 2½” NH thread connectors for soft hose connection. • 1 x 4½” NH thread pumper connection for fire trucks. • 6” inlet connection complying to mechanical joint ANSI/AWWA C111/A21.11 or flange connection ASME B16.5 Class 150. • Operation threads are corrosion protected and for easy operation. • Internal epoxy paint system gives high corrosion protection to hydrants. • Advanced safety couplings and flange design reduces traffic damage to hydrant. • Main valve is easily removed from either the bonnet flange or ground line flange. DESIGN FEATURES • Body Material: Ductile Iron. • O-ring sealed flanges at the bonnet ground line and shoe simplify maintenance by eliminating gasket adhesion at these points, making disassembly The O-rings are easier than flat gaskets to position during reassembly, and provide superior pressure handling. • Hold-down nut - features integral weather seal. Prevents unauthorized removal of hold-down nut or operating nut. Resilient wiper seal prevents water entry and protects from freezing; material resistant to sunlight O-ring provides second level seal. • Safety flange - breaks cleanly to help prevent barrel damage, but strong enough to withstand normal Allows economical repair, adding of extension section, rotation or changing of upper barrel without excavation.
