3 Inch PVC Gate Valve
The Valterra 4303GR is a 3 inch gate valve built from PVC with 304 stainless steel stem and wedge. It uses a spigot connection on both male ends and carries a Class 125 rating. The valve is designed for water media in drain and trap installations.
Suits low-pressure water lines
This valve fits gravity-fed or low-head water systems where operating pressure stays at or below 30 psi and steam pressure does not exceed 15 psi. It is not intended for high-pressure mains, compressed air or hot-steam service above the rated limit.
30 psi maximum operating pressure
The 30 psi operating ceiling is the single figure that decides whether this valve matches the system. Exceeding it risks seat damage and leakage, so confirm the line pressure before specifying this part.
