Features
- Standard Hydronic Heating Circuits
This is a differential by-pass valve from Watts Radiant. It serves two very useful purposes in a hydronic circuit: eliminating water velocity noise and eliminating water hammer. With this valve in place, high-pressure pumps cannot exceed actuator close-off pressure. This increases pump life and reduces wear and tear on the entire system.
