Description
The Honeywell PCV125 is a purpose-built circulating pump check valve engineered to prevent backflow and protect hydronic heating systems from reverse flow damage. Designed for reliable, maintenance-free performance in residential and light commercial boiler applications, the PCV125 installs directly on circulating pump flanges for a compact, leak-free connection.
Key Features
- 1-1/4″ connection size for compatibility with standard circulating pump flanges
- 62 GPM maximum flow rate to support high-demand hydronic systems
- 150 PSI maximum working water pressure for safe, code-compliant installation
- 200°F maximum water temperature rating for hot water heating applications
- Prevents reverse flow and gravity circulation when the pump is off
- Compact, inline design minimizes installation space requirements
- Durable construction suitable for continuous-duty hydronic service
Application
The PCV125 is ideal for use in hot water boiler systems, radiant heating loops, and multi-zone hydronic installations where backflow prevention is critical to system efficiency and equipment longevity. It pairs seamlessly with standard circulator pumps to ensure unidirectional flow and eliminate unwanted gravity circulation between heating cycles.
