VIQUA 650537 UV CoolTouch Temperature Management Valve 3/4"
VIQUA 650537 UV CoolTouch Temperature Management Valve 3/4"
Description
The CoolTouch Valve is a temperature manager for VIQUA UVMAX D, D+, D4, and D4+ Series UV systems or any system with 3/4" MNPT outlet connection. This piece of equipment is useful because the UV system can overheat without constant water flow. To prevent this, the CoolTouch Valve releases small amounts of water when the system reaches temperatures in excess of 95° fahrenheit or 35° Celsius.
Manager Control Valve for: VIQUA D, D+, D4, D4+, D4 Premium UV Systems.
