PNV-125-LF - Proton Digital Mixing Valve

The Nuleus Proton Digitally Controlled mixing valve from Leonard Valve Company is a simple plug-in water temperature control valve. It is self balancing, incorporates the industry's only self cleaning feature and holds temperature to +/-2˚F. Integral check valves are standard on all models, and it has simple setup and simple error coding. Two different sizes are available @ 1" outlet and 1.25" outlet for specific project flow needs. The Nucleus Proton is both ASSE and CSA certified. The electronics are UL Certified and the valve meets the requirements of NSF 372 (Low Lead Content). Options are available for IOT (MODBUS ID WI-FI Gateway) which allows for remote temperature monitoring through the cloud or a building management system.
