Description

Grundfos 97627419 — 3/4″ Sweat 24V Zone Valve with End Switch

The Grundfos 97627419 is a 3/4″ sweat-connection, 24-volt hydronic zone valve designed for dependable flow control in residential and light commercial hot water heating systems. Featuring an integrated end switch, this zone valve signals the boiler or system circulator to activate only when the valve is fully open — improving system efficiency and preventing short cycling.

Key Features

• 3/4″ sweat (SWT) connection for copper pipe installations
• 24V AC actuator for compatibility with standard low-voltage zone control systems
• Integrated end switch for boiler/pump interlock operation
• Normally closed design — valve opens on a call for heat and closes when satisfied
• Suitable for residential and light commercial hydronic heating applications
• Compact, reliable actuator for long service life

Application

This zone valve is ideal for zoned hot water baseboard, radiant floor heating, and fan coil systems. The sweat connection makes it a natural fit for copper piping systems, and the 24V control signal integrates seamlessly with most thermostats and zone control panels.
