MAXIMUM FLOW CAPACITY
Flow Capacities
CAUTION: All thermostatic water mixing valves have limitations. They will not provide the desired accuracy outside of their flow capacity range. Consult the above charts and make certain flow is greater than as shown above.
NOTE: Flow rates will vary depending on existing field conditions. Leonard Valve Company always recommends using CASPAK® sizing software for proper valve sizing and model number applications.
