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 72 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.
Features
Full port ball valve
3/4” compression fitting
Large ball valve handles, easy handling, visible closing position.
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, low pressure drop, manual opener for faster line drain service, spring-actuated-suited for horizontal, vertical or flow down assembly.
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
Pump can be replaced or serviced without draining the system
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.
Fully assembled with flat sealing union connections at most joinsts, including 1" connection nut for the installation on PAW-distribution manifolds.
For stand alone assembly, use the conversion kit with wall bracket from the PAW-assembly accessories.
The insulation of the distribution manifold is integrated in the insulation of the zone module.
