Isolation Ball Valve, Full-Port, Low-Lead

Adjustable Thermostatic and Pressure Balanced Mixing Valve

LEGIOMIX® is an advanced electronic mixing valve with digital control of temperature for commercial domestic hot water systems. The daily exercise function keeps the ball valve free of scale build-up to ensure smooth operation. Rated highest in the market for flow capacity, this feature packed product also has an industry exclusive calendar-based scheduling program for automatic circuit thermal disinfection.The LEGIOMIX® electronic mixing valve provides precise temperature control over very low and very high flow rate demand, minimal pressure drop with a ball valve control element, automatic self-cleaning to prevent scale formation and easy-to-use digital interface with data logging, alarming and status indication. The LEGIOMIX electronic mixing valve is furnished with a controller with LCD user interface that provides a set of programs for circuit thermal disinfection to kill Legionella. The controller is configurable via keypad, or local or remote computer. Depending on the type of system and habits of the user, temperature levels and operation times can be programmed as desired. In addition, it comes standard with monitoring and remote control connections.The LEGIOMIX6000 series electronic mixing valve is powered by 24 VAC. (Caleffi provides a 115/24 VAC transformer in the package.) It is ICC-ES certified to ASSE 1017 and CSA B125.3. It complies with codes IPC, IRC, NPC and UPC for use in accordance with the US and Canadian plumbing codes, and standard NSF/ANSI 372, low lead. Also, it meets the requirement of CSA Z317.1 Special Requirement for Plumbing Installations in Health Care Facilities, certified by ICC-ES.

The Caleffi TankMixer™ is a perfect mixing valve solution to maximize the capacity of modern high efficiency water heaters and minimize installation time. It comes packaged in a kit with everything needed for fast installation including union fittings and industry-exclusive press connections The TankMixer™520_AX series kit combines a three-way thermostatic mixing valve with a cold water cross and flexible pipe for easy installation directly on a typical gas-fired w ater h eater a nd o ther water heaters that now comply with the National Appliance Energy Conservation Act (NAECA). The TankMixer™ maintains the desired output temperature of the mixed water supplied at a constant set value compensating for both temperature and pressure fluctuations o f t he incoming hot and cold water. The mixing valve hot inlet port closes tight to prevent temperature creep in recirculation applications. Also available as body only, for a wide variety of separately-sourced end connections, the angle style body design offers improved fluid dynamics f or better performance and reduces installation labor and materials, eliminating a piping elbow in typical installations. The valve ICC-ES certified to ASSE 1017 and CSA B125.3. It complies with codes IPC, IRC, NPC and UPC for use in accordance with the US and Canadian plumbing codes, and standard NSF/ANSI 372, low lead, as certified by ICC-ES.

The QuickSetter+™ manual balancing valve contains a built-in flow meter and sight gauge, negating the need for differential pressure gauges and reference charts. Circuit balancing is fast, easy and accurate. Constructed of DZR low-lead brass, QuickSetter+ is ideally suited for use in plumbing applications such as hot water recirculation systems. The built-in check valve protects against circuit thermo-siphoning. The outlet dual-scale temperature gauge (optional) verifies the fluid temperature in the circuit. The flow meter sight gauge is dry (not exposed to the fluid) thus eliminating the possibility of gauge clouding/scaling over time. The QuickSetter+ can also be used in heating systems. Peroxide-cured EPDM seals provide chlorine and chloramine resistance and long operating life.

Stable mixed temperature performance with durable construction for long life. Due to the unique mixing chamber design, Caleffi MixCal™ produces very stable mixed water temperature as inlet temperatures and pressures vary. Scale formation is minimized via sliding surfaces constructed of an anti-scale polymer, thus guarding against seizing or erratic mixed temperatures. O-ring seals made from durable peroxide-cured EPDM resist wear from common water treatment additives such as chlorine and chloramines.
