Robertshaw FP-45 Freeze Protection Valve 43°F Opening Temperature

The Robertshaw FP-45 is a freeze protection valve designed to safeguard hydronic heating systems, solar thermal installations, and process piping from freeze damage. This thermostatic valve automatically opens at 43°F (6°C) to allow water flow, preventing ice formation in vulnerable piping systems during cold weather conditions.

Key Features:

• Automatic operation at 43°F opening temperature for reliable freeze protection
• Self-actuating thermostatic design requires no external power source
• Suitable for hydronic heating systems, radiant floor heating, and solar thermal applications
• Protects against costly freeze damage in exposed or unheated spaces
• Durable construction for long-term reliability in demanding environments

This freeze protection valve provides peace of mind for system owners by automatically responding to temperature drops without manual intervention or electrical controls. Ideal for installation in garages, crawl spaces, outdoor mechanical rooms, and other areas subject to freezing temperatures.
