This hydronic control component serves as a critical pressure-regulating solution for residential and commercial heating systems. The Bell & Gossett 113247 differential bypass valve, part number 113247, is designed to automatically maintain minimum system flow rates, preventing pump strain and excessive noise when zone valves or thermostatic radiator valves close.
By monitoring the pressure differential across the heating circuit, the valve modulates flow to recirculate water back to the boiler. This mechanism ensures that the circulator operates within its intended curve, protecting equipment longevity while stabilizing heat delivery across multiple zones.
Key System Performance Baselines:
- Pressure Regulation: Automatically adjusts to bypass excess flow when system resistance increases.
- Hydronic Stability: Reduces hydraulic shock and noise caused by rapid closure of zone valves.
- Equipment Protection: Prevents pump dead-heading and overheating during low-load conditions.
- Energy Efficiency: Maintains consistent boiler return temperatures for optimized burner performance.
⚠️ Application Profile: Ideal for zoning systems with primary-secondary piping, standard hydronic heating loops, and radiant heating manifolds requiring consistent differential pressure management.
