Matco-norca 521C04 Sweat Gate Valve 1-1/2 Inches

Product Description

The MATCO-NORCA 521C04 is a 1-1/2 inch sweat-end gate valve designed for isolation service in residential and commercial plumbing systems. Gate valves of this type provide full-bore flow when open, keeping pressure drop to a minimum across the valve body. The sweat connection requires soldering to copper pipe, making installation straightforward for licensed plumbers working with copper distribution lines. This valve is suited for on-off shutoff duty and is not intended for throttling or flow-regulation applications.

The 521C04 is used in water supply and distribution piping where a full-port shutoff is needed. Common applications include main line isolation, branch shutoffs, and mechanical room installations in both residential and light commercial construction. The 1-1/2 inch end size fits standard Type L and Type M copper tubing used throughout domestic water systems. Plumbers and pipefitters are the primary installers for this class of valve.

Key Features

• 1-1/2 inch sweat (solder) end connections for copper pipe
• Full-bore gate design minimizes flow restriction when fully open
• Suitable for isolation duty in water supply and distribution systems
• Compatible with standard residential and light commercial copper piping configurations

Compatibility

Designed as an OEM-style replacement or new-installation gate valve for 1-1/2 inch copper sweat plumbing systems in residential and commercial water distribution applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off and drain the water supply before cutting into the line or removing an existing valve. Clean and flux all copper surfaces thoroughly before soldering, and allow the joint to cool completely before restoring system pressure. Gate valves should be installed in the fully open or fully closed position only and are not suitable for flow regulation.
