Key specifications
Material: High-quality brass
Connection size: 18 mm
Configuration: Four-way mixing
Application: Hydronic heating and plumbing
How to use
Installation should be performed by a qualified professional to ensure all connections are properly sealed and leak-free. The valve is integrated into the piping circuit where the mixing of supply and return flows is required. Once installed, the manual adjustment handle allows the user to set the desired mixing ratio, thereby controlling the output temperature of the fluid circulating through the heating system.
What to consider before purchase
Verify that the 18 mm connection size matches your existing pipe diameter
Ensure the system pressure and temperature ratings are within the operational limits of brass fittings
Confirm that a four-way configuration is appropriate for your specific heating circuit design
Usage recommendations
Regularly inspect the valve for signs of leakage or mineral buildup, especially in areas with hard water. Ensure the adjustment mechanism remains free to move to maintain precise temperature control throughout the heating season.
