Grundfos 00519852 Isolation Valve Set
The Grundfos 00519852 Isolation Valve Set is a critical component for streamlining the installation and maintenance of Grundfos UP series circulator pumps. Engineered with a 3/4-inch Bronze Union connection, this valve set provides a reliable, leak-free interface for residential and light commercial hydronic systems. The bronze construction ensures superior corrosion resistance, making it an essential choice for open-loop potable water systems or closed-loop heating applications where longevity is paramount. By integrating these service valves, technicians can isolate the pump from the rest of the hydronic loop without draining the entire system, significantly reducing downtime during impeller inspections or motor replacements. This kit includes all necessary gaskets and hardware to ensure a tight seal and proper alignment with the pump housing. Whether you are performing a new boiler install or upgrading an existing hot water recirculation system, these valves provide the professional-grade shut-off capability required for code compliance and ease of serviceability.
Key Benefits for Technicians- Bronze construction prevents dezincification and ensures compatibility with potable water standards.
- Full-port design maintains peak flow rates and minimizes pressure drop across the circulator.
- Integrated union connection allows for fast pump removal and re-installation without cutting pipe.
- Heavy-duty handle provides positive shut-off and clear visual indication of valve position.
- Compatible with a wide range of Grundfos UP and UPS models utilizing standard union threads.
Is the Grundfos 00519852 lead-free for potable water use?
Yes, the bronze alloy utilized in this isolation valve set is designed to meet the requirements for domestic hot water systems.
What is the maximum pressure rating for this valve set?
These valves are typically rated for standard hydronic operation up to 150 PSI, matching the performance specifications of compatible circulator pumps.
Does this set include both the supply and return valves?
This item is sold as a pair (set of two) to provide isolation on both the suction and discharge sides of the pump.
