The Valterra 3-piece pneumatic gate valve is designed for compatible 3 inch threaded systems that require controlled shutoff through pneumatic actuation. Gate valves are useful because they provide a dedicated open-or-close control point in the plumbing line, and the 3-piece construction adds service advantages when maintenance or replacement becomes necessary.This replacement is especially useful in installations that already rely on pneumatic control and need the correct 3 inch FPT configuration instead of a slip-based or manual alternative. The threaded layout also makes it a practical fit where removable plumbing connections are preferred.The 9307 is a strong service option when a compatible larger-line system needs a pneumatic gate valve with the correct thread format and a more maintenance-friendly design.
