Nibco S-595-Y-66-LX-1 Bronze Ball Valve 3-piece

Product Description

The NIBCO S-595-Y-66-LX-1 is a three-piece, full-port bronze ball valve designed for commercial, mechanical, and industrial piping systems. It operates with a quarter-turn (90 degrees) open-to-close motion, providing fast, reliable shutoff. The valve features copper-by-copper (CxC) solder end connections for straightforward installation into copper pipe systems. The LX-style handle and three-piece body construction allow for in-line servicing and easy ball and seat replacement without removing the valve from the line. Licensed plumbers and pipefitters are the primary installers for this type of valve.

This valve is suited for residential and commercial plumbing, HVAC hydronic systems, and mechanical room applications where a durable, full-port bronze shutoff is required. The solder-end configuration makes it a direct fit into standard copper tubing installations. An optional NIB-SEAL insulated handle is available to eliminate condensation in systems where surface sweating is a concern.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and NIBCO published technical data. Shut off the water supply and depressurize the line before soldering or servicing. Refer to the NIBCO valve selection guide and technical data sheet for engineering and torque specifications. Do not apply excessive heat directly to the valve body during soldering, as this can damage internal seals and seats.
