Nibco NHA701F Gate Valve 3 Inch Flanged Ductile Iron 150

Product Description

The NIBCO NHA701F is a non-rising stem gate valve designed for industrial and commercial piping systems requiring reliable full-bore shutoff. Built with a ductile iron body and a solid wedge disc, this valve handles the mechanical demands of high-cycle service in water, HVAC, and general fluid systems. The bolted bonnet design provides a secure, field-serviceable seal, and the flanged raised face end connection conforms to standard 150-class flange patterns. At 60 pounds, this is a substantial component intended for permanent installation by licensed plumbers or pipefitters working on 3-inch pipe systems.

This valve is suited for 3-inch pipe runs in commercial plumbing, industrial process piping, HVAC hydronic systems, and mechanical rooms where full-port shutoff is required. The 150 pressure class rating makes it appropriate for standard low-to-medium pressure water and fluid service applications. The wheel handle allows manual operation with a conventional valve wrench or by hand in accessible installations. Flanged raised face connections align with ANSI 150 flange standards common in commercial mechanical systems.

Key Features

• Non-rising stem design saves vertical clearance in tight mechanical spaces
• Ductile iron body offers greater toughness and impact resistance compared to cast iron
• Solid wedge disc provides reliable full-bore shutoff with low flow restriction
• Bolted bonnet construction allows field servicing and repacking without valve replacement
• Flanged raised face end connection suits standard ANSI 150 flange mating surfaces
• Wheel handle enables manual operation without special tools

Compatibility

Designed as an OEM-style replacement or new-installation gate valve for 3-inch ANSI 150-class flanged piping systems in commercial plumbing and industrial mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME B31 piping codes. Isolate and depressurize the system completely before removing or installing any flanged valve. Inspect flange gaskets and fastener torque patterns per standard flanged joint procedures, and verify flange bolt circle alignment before tightening. Do not use this valve for throttling service; gate valves are intended for full-open or full-closed positions only.
