4" Forged Brass Full Port Ball Valve

The Legend Valve 101-431 is a 4-inch S-2000 CXC full port ball valve built from forged brass. It suits installers and maintenance teams who need an unobstructed flow path in compressed-air or vacuum-pump lines.

Forged Brass Body with CXC Connections

The forged brass construction resists corrosion and handles the pressure cycles common in air-compressor installations. CXC copper sweat ends let the valve be soldered directly into copper pipework, creating a permanent leak-free joint without threaded adapters.

Replaces Restricted-Port or Threaded Valves

Swapping a standard-port or threaded valve for this full-port model removes the internal bottleneck that can reduce compressor efficiency. The upgrade is worth it when system pressure drop across the valve is measurable or when soldered joints are preferred over threaded connections for long-term reliability.
