Nibco h-81407whv 2 in Press Pump Isolation Valve

Product Description

The NIBCO h-81407whv is a 2-inch press-connection pump isolation valve featuring a rotating flange design for residential and light commercial hydronic and plumbing systems. Built to lead-free standards, this valve allows a technician to isolate a circulator pump or inline pump for service or replacement without draining the entire system. The rotating flange simplifies alignment during installation and reduces the effort required to mate the valve to a pump flange face. Licensed plumbers and hydronic system technicians are the primary installers of this valve type.

This valve is suited for closed-loop hydronic heating systems, domestic water recirculation loops, and similar pressurized piping applications where pump serviceability is a design requirement. The press-connection end eliminates the need for soldering or threaded fittings at the pipe connection point, making it a practical choice for retrofit and new construction installs where open-flame work is restricted or undesirable. It is intended for 2-inch nominal pipe size installations.

Key Features

• 2-inch press-connection end for flame-free installation on copper or compatible tubing
• Rotating flange allows angular adjustment for precise pump alignment
• Lead-free construction meets applicable potable water and plumbing code requirements
• Pump isolation design enables in-line pump removal without full system drain-down
• Flange-style pump interface suits standard circulator and inline pump bolt patterns

Compatibility

Designed as an OEM-style replacement or new-installation pump isolation valve for 2-inch press-fit piping systems in residential and light commercial hydronic and recirculation applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified hydronic systems technician in accordance with local plumbing codes and IPC requirements. Depressurize and isolate the piping system before beginning work. Press connections require a calibrated press tool with the correct jaw size for the fitting diameter. Verify the rotating flange is properly aligned and fasteners are evenly torqued to the pump flange before returning the system to service.
