Classic High-Low Systems

Leonard High-Low Systems solve problems which occur with oversized thermostatic mixing valves. These precisely designed and preassembled systems employ a dual mixing valve and pressure regulating valve arrangement to provide accurately mixed water temperature from extremely low flows of 0.5 or 1.0 GPM (1.8 or 3.7 l/m), to high flow requirements. 
 
Classic High-Low Systems are installed to control water temperature for building hot water systems - hotels, hospitals, commercial/institutional installations. 
 
Automatic 7 Year High-Low System Thermostat Warranty! Only Leonard offers this extended warranty on all of its High-Low Systems. 
 
Caspak® Sizing Program is now available in CD to size Leonard High-Low Manifold Systems and valves and is the only sizing program which also includes access to product drawings and piping schematics.
