Graco 116473 – Vented Ball Valve .250
Overview
The Graco 116473 Vented Ball Valve .250 is a genuine OEM vented ball valve designed for fluid or air‑handling systems. Its ¼″ port size and vented/bleed‑type design enable safe control and release of pressure or fluid when closing the line — helping prevent pressure lock and protecting seals or internal components. This makes it ideal for sprayers, pump carts or fluid‑delivery systems where pressure buildup must be safely relieved.
