Many rooms are no longer heated and cooled by two separate systems, but by an integrated heating and cooling ceiling, for example. Kieback&Peter has the perfect combination for this purpose: the DS5 rotary actuator with the CBV 6-way ball valve. This allows you to combine heating and cooling systems with minimal space, material and work requirements. The practical duo replaces four conventional control fittings. They regulate the flow of heating and cooling media precisely – even with a very small Kvs value (fluid flow rate). As you would expect of German quality products from Kieback&Peter, the set is maintenance-free. After quick installation, it provides continuously efficient system operation – provided hydraulic balancing has been completed during installation.

The product combination replaces four standard drives and valves.

For installation of control fittings, too: time is money. For combined heating and cooling systems, installing conventional fittings involves a lot of work. The installer has to connect four conventional valves and drives for the feed and return. A 6-way valve with actuator can be installed much faster. The smart product combination from Kieback&Peter has even more installation-friendly details. For example: the drive automatically detects the end position of the valve when the operating voltage is switched on and initializes itself.

3 good reasons for the smart duo: DS5 + CBV

Four conventional valves plus four actuators usually cost more than one 6-way valve with actuator. The installation time is also reduced with Kieback&Peter’s solution: first, there are fewer parts to fit. Second, a control cable is already connected to the actuator. The bottom line is that the durable combination saves developers and operators money.

The standards ISO 20653 and DIN EN 60529 apply to International Protection (IP). They define which electrical equipment is suitable for which environmental conditions. The DS5 actuator from Kieback&Peter meets protection class IP 54. Thus, it is protected against any contact, large amounts of dust and spray water on all sides. This allows use in a wide range of operating environments, including outdoors.

Kieback&Peter’s set comes with Kvs diaphragms. The specialists on site can carry out hydraulic balancing with these: the Kvs diaphragms are used to adapt the flow rate through the valves precisely to the individual needs of the connected consumers. The heating and cooling devices in the room thus receive only as much hot or cold water as they really need. Correct hydraulic balancing can save up to 15 percent of your energy.

MD15/MD50 Small Actuators

Operate and grasp valves precisely

The small actuators of the MD15/MD50 series control valves in heating and cooling systems using signals from the automation system. They fit all standard radiator, small and zone valves and can open and close them infinitely variable. As they are from Kieback&Peter, there’s much more to them than normal actuators: they learn about the valves independently and initialize themselves automatically. They therefore optimize the control and consumption of resources. The adjustable characteristic curve of the MD15/MD50 is another advantage: it can be adapted precisely to the energy consumption of the consumers. In conjunction with smart control, the small actuators ensure maximum efficiency with consistent comfort.

Smart and flexible

Optimized for any application, whether digital, analog or wireless.

Flexible actuators for various use cases

Sales engineer in building automation working at Kieback&Peter

Heating and cooling circuits have various consumers with upstream control valves. New builds and renovations: over time, the number of different valves and manufactures often increases. For efficient building automation, consultants and operators therefore opt for flexible small actuators that can adapt to all conditions on-site. MD15/MD50 actuators meet this requirement by offering variants for various communication protocols:

  • MD15-BUS/MD50-BUS: The intelligent bus actuators are equipped with two communication interfaces, BACnet MS/TP and Modbus. As a result, they provide fine-grained energy-efficient regulation of the heating or cooling supply at all points in the building. 
  • MD15-Funk: The radio actuators for room or zone valves perfectly suit for installation in existing buildings. They communicate via EnOcean and are easy to install. 
  • MD15 / MD50: The analog actuators in combination with a room controller are a cost-effective and smart solution.

5 good reasons for MD15/MD50 actuators

The actuators are designed for different communication protocols: analog, digital (BACnet MS/TP and Modbus) or via radio. They perfectly suit for new as well as existing buildings.

The MD15/MD50 small actuator control can follow individual characteristic curves. The valve stroke then adapts precisely to the energy needs of the downstream consumer. A radiator thus heats no more than required. This saves energy and cuts operating costs.

MD15/MD50 small actuators are compatible with a wide range of valves. The actuator automatically detects the upper and lower end position of the valve stroke and adapts the adjustment range to it. High quality of control and consistently reliable operation are the result.

Facility managers have to know exactly what is happening in their systems. To maintain an overview, for example, they use Qanteon – the Kieback&Peter software for integrated energy and building management. Efficient, safe and convenient operation is only possible, however, if the operator can call up every detail of the system. MD15/MD50 small actuators therefore carry out more than just control commands for building automation. They continually notify the controller and management software of the position of the valve spindle. Energy and facility managers can thus analyze their system data even better and optimize operation.

MD15/MD50 small actuators have valve anti-lock protection that the operator can activate as required. The software function prevents the valve from sticking after long operating breaks. The valve spindle is moved automatically at certain intervals. This supports smooth operation and improves system reliability.

MD15/MD50 support these protocols natively:

Electric voltage signals between 0 V and 10 V or 3-point signals control the MD15/MD50 small actuators. The MD15-FTL-HE and MD15-CFL-HE wireless models give native support to this protocol:
