Nibco 39923699220 Gate Valve 4 in Flanged 250 Psi

Product Description

The NIBCO 39923699220 is a 4-inch flanged gate valve from the F-637-33 series, built for reliable shut-off service in commercial and industrial piping systems. The body is ductile iron with 316 stainless steel trim, providing corrosion resistance in demanding service environments. It carries a 250 psi pressure rating at 150 lb pressure class and is rated to 100 degrees F. A 10-inch handwheel actuator provides manual operation. The raised face flanged end connection conforms to standard 150 lb flange bolt patterns, making it straightforward to integrate into existing piping layouts.

This gate valve is suited for commercial and industrial applications including hot and cold water systems, HVAC piping, steam service, compressed air, gas distribution, and general utility services. The raised face flanged configuration makes it appropriate for use in process piping, mechanical rooms, and utility infrastructure where flanged connections are specified. Installation is typically performed by licensed plumbers or pipefitters working on commercial or industrial mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Isolate and depressurize the system fully before removing any existing valve or making flange connections. Verify gasket material compatibility with the intended media before assembly. Flange bolts should be torqued in a cross pattern per the applicable piping standard for the pressure class.
