New Generation High-Low Systems

New Generation Leonard High-Low Systems provide economical new solutions for problems associated with oversized single thermostatic mixing valves. These precisely designed and preassembled systems employ a simple dual mixing valve arrangement to provide accurately mixed water temperature from extremely low flows of 1.0 GPM (1.8 or 3.7 l/m), to high flow requirements.  
 
New Generation 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.
