M-8220 High-Capacity™

The M-8220 high capacity manifold is ideal for hydronic radiant applications that require high flow rates such as snow & ice melt systems or projects with large floor areas (warehouses, commercial garages, airplane hangars, manufacturing facilities, etc.) This versatile manifold can also be used in the mechanical room for flow distribution in hydronic systems where each branch is supplying one or more zones of radiant panel manifolds, radiator panels, baseboard, fan coil units, etc. The M-8220 provides full isolation at each header and circuit loop with color coded handles. The header valves are available with standard pipe thread or press style connections. Depending upon circuit balancing requirements, FNPT and Press circuit isolation valves are available. many components are compatible with our M-8000, M-8100 and M-8200 manifolds - making the Legend manifold series the most flexible manifold system on the market.

Want a thermometer instead of a standard loop isolation valve? Call Customer Service at (866)752 -2055

Substitute one or more multiple pairs of loop isolation valves with thermometer, in place of the standard loop isolation valves included with the manifold kits. The supply and return thermometer can provide means to determine delta T and help balance flow rates. Call Customer Service at (866)752 -2055 to make application adjustments to your order.
