Use in closed loop design. Low Temperature Zone Modules K33 equipped with an adjusted thermostatic actuator and an adjustable bypass valve (0-50%) . K33 is designed to provide constant supply temperatures to the radiant system. Depending on the geographic location of the installation, periodic adjustments of the temperature may or may not be necessary. Rotating the dial of the thermostatic head to a higher number will provide for hotter temperatures.
The designer of the radiant system must ensured the range of temperatures provided by the control is suitable for the installation. The K33 can handle radiant load demands of up to 37.3K BTU's at a 20°F/11K differential. The mixing valve closes on temperature rise. Multiple K33 modules can be used to separate the distinctive temperature requirements between manifold. No special piping, just 2 connections and your installation is complete.
1” NPT female connections
Large ball valve handles, easy handling, visible
Design insulation with optimized function
made of durable elastic EPP, 100% insulation of the fittings, ventilation
openings to cool the pumps.
Free access to the pump head by simply
pulling off the cover
Check valve in return pipe prevents noise
when electronically controlled pumps are used, manual opener, 200mm water
column (7.9” head), spring-operated, thus suitable for horizontal and overhead
Supply and return line can be changed on
site, To change the supply line, a mixing valve conversion kit is necessary.
Check Valve integrated in the mixing valve, prevents unwanted circulation.
All water-carrying parts are made of brass, thermostat-adjustable in the range of 68°F -140°F. When the adjusted temperature is exceeded a switch is activated and switches off the pump.
All metal temperature gauges can be pulled
off, integrated in the ball valve with an immersion sleeve.
Fully assembled with flat gaskets
PAW heating circulation pumps-flanged 2-bolt
already installed, integrated in the insulation, pressure tested, series
3-way mixing valve with bypass 0-50% and thermostat control completely made of brass, set by the thermostat and the sensor, the setting is done manually, the bypass can be set at the front.
Flat sealing 1.5" male connections including 1.5" union nut for the installation on PAW modular distribution manifolds, Individual installations with wall brackets are possible by using the PAW mounting equipment.
