TempFlow™ Thermostatic Zone Valve

Model Number:  TZV Series
The thermostatic zone valve shall have a solid brass body with corrosion-resistant internal components. It shall include an integral check valve and strainer to prevent backflow and filter debris from entering the valve. Zone temperature adjustment shall be from 100°F to 160°F (38°C to 71°C) and is made using an Allen wrench and a locknut on the bonnet prevents unauthorized or accidental temperature adjustment. Valve shall proportionally modulate to maintain zone temperatures based on heat loss and shall stabilize pump demand to prevent cycling. The TZV modulates its Cv from a maximum of 0.7 to a minimum of 0.2 with a 10°F (5.6°C) change in zone temperature. The valve shall not have positive shut-off thereby preventing pump dead-heading and/or subsequent overheating.
Product Function:
The Acorn TZV is a thermostatically controlled zone balancing valve which automatically maintains the domestic hot water loop/zone temperature. By simply installing the valve after the last hot water device in each loop, it will self-adjust and balance the recirculated flow and heat loss of each TZV controlled zone. This ensures fast and consistent delivery of hot water to all fixtures all the time.
