Use in closed loop design. Low Temperature Zone Module K32 replaces conventional injection mixing systems. In conjunction with an electronic reset control and direct drive actuator, the K32 modulates a 3-way valve, diverts and mixes radiant return water with hot water from the boiler. The constant speed system circulator delivers the required water temperature to the radiant loop manifolds.
The K32 can handle radiant load demands of up to 174 KBTU’s. Your current method of zoning the radiant loops (manifolds, zone valves, etc.) does not change with the installation of the K32. Multiple K32 modules can be used to separate the distinctive temperature requirements between manifolds. No special piping, just 2 connections and your installation in complete.
1.25” 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, the mixing valve can be changed without difficulties.
All water-carrying parts are made of brass
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 completely is made of brass, characteristic curve prevents variation in temperature, flow pipe can be shut off, thus the pump can be replaced or serviced without draining the system.
Flat sealing 2" male connections including 2" union nut for the installation on PAW modular distribution manifolds, Individual installations with wall brackets are possible by using the PAW mounting equipment.
