Recirculation thermal balancing valve

1164 series

Function

The ThermoSetter™ 1164 series 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 105°F to 150°F (40°C to 65°C) temperature scale

indication. The adjustment knob is lockable for tamper-proofing. 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 valve complies with NSF/ANSI/CAN 61, as certified by ICC-ES, file PMG-

1512 (180°F/82°C Commercial Hot), and complies wirh NSF/ANSI 372, low lead

laws, as certifed by ICC-ES, file PMG-1360. It also meets codes IPC, IRC, UPC

and NPC for use in accordance with the US and Canadian plumbing codes.

Flow characteristics 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 = .35) when the incoming water temperature is equal to the set-point position of the adjustment dial. The valve opens as incoming water temperature drops.
PAGE 4
Temperature adjustment Installation Set the desired recirculation system temperature by turning the adjustment knob. The graduated scale shows the temperatures at which the adjustment knob can be set. Before installing the ThermoSetter, flush the pipes to make sure that impurities in system will not interfere with valve performance. Strainers of sufficient capacity at the inlet from the water main are highly recommended.

Maintenance Accessories The adjustable balancing cartridge can be removed from the valve body for periodic inspection, cleaning or replacement. ThermoSetter codes 116440A(C) and 116450A(C) come standard without temperature gauge, but temperature gauge, code 116010 can be field-installed later for confirming the temperature of the hot water in the circuit.
