Nibco S-595-Y-66-34 Bronze Ball Valve 3/4 Inch

Product Description

The NIBCO S-595-Y-66-34 is a three-piece bronze ball valve designed for quarter-turn operation, moving from fully open to fully closed in a 90-degree rotation. Solder end connections provide a clean, permanent installation suited to copper piping systems. The lever handle allows fast, positive shutoff and clear visual indication of valve position. This valve is installed by licensed plumbers and pipefitters in commercial, mechanical, and industrial piping systems where reliable flow control is required.

The S-595-Y-66-34 is sized at 3/4 inch and fits into copper solder-end applications across a wide range of commercial and mechanical piping systems. Its three-piece body construction allows in-line maintenance and seat replacement without removing the valve from the line. The bronze body is well suited to water service, hydronic heating and cooling systems, and general plumbing applications where a compact, full-port shutoff valve is specified.
