Recirculation thermal balancing valve

116 series

Function

The ThermoSetter™ adjustable thermal balancing valve is used for

automatic balancing of recirculation loops in domestic hot water systems, to

speed hot water delivery, reduce water waste and save energy. The internal

thermostatic balancing cartridge automatically modulates flow to ensure a

constant temperature in the recirculation piping system. The 116 Series has

an adjustment knob with 95°F to 140°F (35°C to 60°C) temperature scale

indication. An integral dry-well holds a slide-in temperature gauge for local

indication, or a sensor for remote temperature sensing. The optional check

valve protects against circuit thermo-syphoning.

The 1162xx Series is available with a “disinfection” by-pass cartridge, for

use in systems which are designed to perform thermal disinfection for

prevention of Legionella. When the disinfection cartridge senses 160°F

(70°C) water, indicating disinfection control mode, it automatically opens a

by-pass flow path to allow sufficient flow for disinfection to occur. When the

temperature drops back to normal range, the disinfection by-pass cartridge

closes to return flow control to the balancing cartridge.

The 1163xx Series is also available with a "disinfection" valve that is

controlled by a 24V spring return thermo-electric actuator, rather than

thermostatically, thus allowing thermal disinfection mode to be controlled

remotely by an automation system.

Operating mode G (gpm) Temperature control Cvmax (2.1) Operating mode B - Automatic thermostatic disinfection The 1162xx series operating characteristic curves for operating mode B are curves 1, 2, 3 and 4. When a temperature higher than about 155°F (68°C) is reached, a by-pass passage begins to open to activate the second thermostatic cartridge which controls the thermal disinfection process, allowing flow independent of the operation of the thermostatic balancing cartridge.
PAGE 4
Flow characteristics Temperature adjustment and locking The ThermoSetter™ thermostatic balancing valve is designed to balance individual branches of domestic hot water recirculation systems, based on the temperature at the valve. It automatically modulates flow to maintain hot water availability to all fixtures in the branch circuit. The valve is at minimum flow (Cv = .23) when the incoming water temperature is equal to the set-point position of the adjustment dial.

Maintenance Accessories Both the adjustable balancing cartridge and the disinfection control cartridge can be removed from the valve body for periodic inspection, cleaning or replacement. ThermoSetter™ codes 116140A and 116150A come standard without temperature gauge, but temperature gauge, code 116010 can be fieldinstalled later for confirming the temperature of the hot water in the circuit.
