Ball Valve 1-PC
Category: Brass & Bronze Valve
Overview
One-piece brass ball valves provide reliable quarter-turn on/off isolation in a compact, lightweight body machined from a single brass forging. The one-piece body eliminates body joint leakage paths and reduces the number of sealing surfaces compared to two-piece or three-piece designs. Standard PTFE seats deliver bubble-tight shut-off across the full rated pressure range. Suitable for potable water, compressed air, natural gas, and general industrial utility services.
