PVC gate valve for water systems

The Valterra 4304GR is a 3-inch PVC gate valve rated Class 125 for water service. It uses a rising stem made from 304 stainless steel with a solid stainless steel wedge and stainless steel seats. The TPE seals and welded PVC bonnet are built for cold-water lines operating at up to 30 psi.

Installers needing low-pressure isolation

This valve suits plumbers and maintenance teams who need a straightforward shut-off for cold water at modest pressure. It is not intended for steam lines above 15 psi or for applications that require flanged connections. Buyers who need higher pressure ratings or different end connections should look at alternative valve types.

30 psi maximum operating pressure

The 30 psi cold-water pressure limit is the key figure that determines whether this valve matches the system design. Steam service is limited to 15 psi. Both connections are male IPS threads, so the piping must accept that thread form. Verify the pressure requirement before specifying this model.

Questions about this item

How do I install the Valterra 4304GR gate valve with its 3 in IPS male connections, and what step is often missed?

Apply PVC primer and cement to both male IPS ends and the mating female fittings, then push fully home with a quarter turn; the step often missed is allowing the joint to cure under pressure before introducing water flow.

Which components of the Valterra 4304GR will need replacement after extended service?

The TPE seal and the 304 stainless steel wedge face are the wear items; the seal can harden and the wedge seating surface can score, requiring a rebuild kit to restore drip-tight shut-off.

What pressure limit appears first when the Valterra 4304GR is used continuously in a water system?

The 30 psi maximum operating pressure for water is the first limit reached; sustained pressure above this rating will stress the PVC body and welded bonnet before the 15 psi steam rating becomes relevant.
