-Heating manifold 3000 - Flowmeter If the German Construction Contract Procedures for orders are agreed, each specialized craftsman is legally obligated not only to make the hydraulic balancing during the installation of floor heatings but also to prove it (VOB, part C, DIN 18380-heating systems). It s also state-of-the-art to balance heating systems hydraulically. Furthermore the hydraulic balancing is physically mandatory, because water searches the line of the least resistance. The hydraulic balancing: The individual circuits of a floor heating have to be coordinated and adjusted in that way, that each circuit receives only the volume flow which is necessary for the respective heating output. The required volume flow can be easily and quickly adjusted by the standard integrated flowmeter of the SBK Heating manifold 3000. Procedure: Heating system has to be completely filled an deaerated, operating pressure has to be existent! Close all flowmeters of the return manifold, open all valves of the supply manifold. Adjust volume flow of the first circuit by turning the transparent plastic pipe according to the heat requirement calculation (use handwheel of the supply valve).

- Insulating spout By use of the SBK heating manifold 3000 in space cooling systems, condensation can be formed on the metal parts if the rope's point is undercut. Especially in the area of the clamp ring screw connection this can be mainly prevented by use of the insulating spout. The insulating spout is suited for clamp ring screw connections external thread euro cone ¾ and pipe diameter from Ø 12 to 20 mm. Picture 1 Assembly 1. Push insulating spout over the pipe before assembly of the clamp ring screw connection. 2. Screw on pipe with screw connection as usual on the manifold circuit. Now the insulating spout can be pushed over the clamp screw connection until the sealing lip lays on the manifold module. clamp screw connection insulating spout insulating spout plastic pipe plastic pipe Picture 2 Picture 3 Page 8
-Multizone 3000 The SBK-Multizone 3000 can easily combine 2 or 3 heating circuits into one control zone due to its modular nature. The hydraulic balancing of the heating circuits remains possible by the flowmeter in the return module. Specification of the components: Zone valve 3000, with thermostatic valve Controls the flow of the heating water to the following Multizone heating circuits. Change-over to electric actuator possible. Attention: First module of the Multizone in flow direction Intermediate module 3000 Pass to following modules (for both single circuits and Multizone heating circuits).

Differential pressure relief valve for Heating manifold 3000 Description: The SBK Differential pressure relief valve for Heating manifold 3000 has the function to maintain a minimum water circulation or to reduce flow noises in a heating or cooling system. For that a Bypass-tube is connected between a Supply module and a Return module of the heating manifold. Instead of the flowmeter the Differential pressure relief valve is fitted in the Return module. The Differential pressure relief valve opens the Bypass in case of the differential pressure between supply and return is higher than the set value at the Differential pressure relief valve. So the heating system provides a minimum of water circulation also when all valve actuators are closed. For example mounted in an heat pump system. Advantages SBK Differential pressure relief valve: - infinitely adjustable pressure setting - Display Set value by scale - easy fitting / refitting - Bypass-tube included handwheel supply valve (open) Differential pressure relief valve Bypass Set Value 0 1 2 3 4 5 Differential pressure [bar] 0 0,1 0,2 0,3 0,4 0,5 Application area: Suitable for water, water glycol mixture up to 30% concentration.
