Mueller Streamline a 18963 Ball Valve Ftg X Ftg 3/4 in

Product Description

The MUELLER STREAMLINE a 18963 is a CYCLEMASTER full-port ball valve configured with FTG (fitting) x FTG end connections in a 3/4-inch connection size. It is designed for shutoff and flow control in copper piping systems and is rated for a maximum allowable pressure (MAP) of 775 psi. The valve carries an operating temperature range of -40 degrees F to 300 degrees F, making it suitable for both hot and cold service lines. Licensed plumbers and HVAC technicians install this type of valve during new construction, system retrofits, and service isolation work.

This ball valve is suited for residential and light commercial plumbing and hydronic heating systems where a reliable, quarter-turn shutoff is required. The FTG x FTG configuration is intended for direct sweat-solder installation into copper tubing systems without additional fittings. The Cv flow coefficient of 19.00 indicates a low-restriction flow path appropriate for typical domestic water and hydronic line sizes at this connection diameter.

Key Features

• 3/4-inch FTG x FTG end connections for direct sweat-solder installation into copper piping
• Maximum allowable pressure of 775 psi for high-pressure system compatibility
• Wide operating temperature range: -40 degrees F to 300 degrees F
• Cv of 19.00 for low-restriction, full-flow performance
• Compatible seal cap kit: A 17843 for field service and maintenance

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for 3/4-inch copper piping systems using FTG sweat connections. Seal Cap Kit A 17843 is the factory-specified service kit for this valve.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician familiar with sweat-solder copper fittings. Shut off and drain the water or hydronic system before beginning work to prevent burns and flooding. Use proper flux and solder rated for potable water or hydronic service as applicable, and allow the valve body to cool before operating the handle. Reference local plumbing codes and IPC guidelines for isolation valve placement requirements.
