Xylem DA0391 6-Bolt Flanged Float Switch Assembly for Vacuum Heating Units

The Xylem DA0391 is a six-bolt flanged float switch assembly designed as a liquid level control device for HVAC and heating applications. This float switch is specifically used on Series VLR and Series VLRS vacuum heating units, and is also compatible with condensate and boiler feed pumps.

Key Features:

• NEMA 4X rated enclosure provides protection against moisture and dust intrusion
• Durable stainless steel construction for long service life
• Magnetic reed switch mechanism activated by internal float movement
• Complete assembly includes float and rod attached to a flanged 6-hole mounting plate
• Six-bolt flange design for secure installation on pumps and tanks

The float switch operates by using a magnetic float that rises and falls with liquid levels, activating an internal reed switch at preset points. This reliable level control prevents overflows and ensures optimal liquid levels in heating systems, cooling towers, condensate drains, and sump pump applications. The weatherproof NEMA 4X enclosure makes this switch suitable for harsh environments where moisture and contaminants are present.
