Brass Stop Valve FERRO KOR7Z 6/4" yellow

FERRO KOR7Z 6/4" yellow is a brass stop valve designed for manual shut-off of fluid flow in plumbing systems. Constructed from brass, the valve delivers mechanical durability and inherent corrosion resistance suitable for both residential and light commercial water installations. The 6/4" threaded connection provides a secure joint with compatible fittings and enables straightforward installation in supply lines where a robust isolation point is required.

Advantages

The brass body ensures long-term mechanical strength and resistance to common forms of corrosion encountered in potable water systems. The manual actuation mechanism allows precise control for isolation, maintenance, or emergency shut-off operations. A yellow finish improves visual identification in manifold or service areas and simplifies locating the valve among other pipeline components. The compact design minimizes space requirements while maintaining reliable sealing performance.

Suitable for

• Isolation of cold and hot water supply lines in homes and apartment buildings
• Service shut-off points for maintenance in commercial plumbing installations
• Use as an isolation valve before meters, fittings, or appliances
• Replacement of worn or leaking stop valves in existing pipelines

Key specifications

• Material: brass body and internal components
• Connection size: 6/4" threaded inlet/outlet
• Operation: manual shut-off valve
• Finish: yellow coating for identification
• Application: potable water and general plumbing systems

How to use

Mount the valve into the pipeline by threading it into compatible fittings or adapters that accept a 6/4" connection, using appropriate sealing material on the threads to prevent leaks. Tighten to recommended torque for brass fittings, avoiding excessive force to prevent thread damage. Operate the valve by turning the handle to open or close the flow path; verify the valve is fully closed when isolating a section for maintenance. After installation, inspect connections under pressure to confirm leak-free operation.

Usage recommendations

For reliable performance, install the valve in accessible locations to allow periodic inspection and operation. Use thread sealant or PTFE tape rated for potable water systems. Avoid exposing the valve to aggressive chemicals or prolonged high temperatures beyond typical domestic hot-water ranges. When replacing an existing valve, ensure compatibility of the 6/4" threads and check mating components for wear before assembly.
