4-Inch Flanged Gate Valve

This Nibco F619RW gate valve controls water flow in plumbing systems with a ductile-iron body and ANSI Class 125 flanges. It is built for installers who need a 300 psi non-rising stem valve for municipal or commercial water lines.

Replaces Worn Iron Gate Valves

The resilient EPDM wedge and bolted ductile-iron bonnet upgrade older metal-seated units that leak or bind after years of service. The jump is worth it when a system requires a positive shut-off at 300 psi water pressure or 250 psi steam pressure.

Suits Water Distribution Contractors

It fits engineers specifying ductile-iron flanged valves for ambient water service up to 300 psi. Buyers needing a rising stem, a higher pressure class, or a different flange standard should look at alternative valve configurations.

Questions about this item

What flange class and bolt pattern does the 4-inch valve require for mounting?

The valve uses an ANSI Class 125 flange connection, so the mating flange must match that class and bolt circle.

How is the valve installed in the pipeline and what common step is missed?

Bolt the flanged ends to the pipe flanges with a gasket, then tighten bolts in a cross pattern; the step often missed is the cross-pattern torque sequence.

Which internal parts will need replacement after extended service?

The resilient wedge with EPDM seat and the EPDM seals are the wear items that typically require replacement over time.
