The AB-QM can be used seperately as an automatic flow limiter valve or as a combined flow limiter and control valve when fitted with an actuator. In addition, the setting is extremely user friendly and reliable, making the AB-QM maintenance free.
The AB-QM valve is the obvious choice for balancing and controlling terminal units such as fan-coils, chilled ceilings and air handling units. For the Commissioning Engineer it is straight forward to set the maximum designed flow - just turn the presetting scale at the desired flow. A built-in diaphragm then maintains a constant low differential pressure across the setting cone on the AB-QM. This ensures that the maximum set flow is not exceeded.
Upgrading the valve
By fitting the AB-QM valve with one of four different types of Danfoss actuators, the AB-QM valve is upgraded to a control valve with full authority supplying both temperature control and flow balancing in one valve. As a result, the AB-QM can be used in all cooling and heating applications.
Due to the low differential pressure across the setting cone it is possible to use small actuators with a low closing force.

• Non-electric proportional control
• Direct acting valve controller
• Easy set and install process
• Suitable for ABQM valves DN10–DN20
• Range limiting function
The FEV-Z climate sensor is a proportional controller which opens or closes an ABQM automatic flow limiter valve dependant on the difference in temperature from the set-point. If
the temperature in the room is equal or below setpoint then the valve will remain open, closing should the space temperature increase above set-point.
The FEV-Z is used in climate systems with ceiling, floor or radiator heating. |

adjusted to match the load in the riser by control of return water temperature.
QT is dedicated to be used with ABQM automatic balancing and control valve.
ABQM together with QT is a complete one-pipe solution: ABQT. |

ASV-I is a combined adjustment and shut-off valve designed for installation in the flow pipe. It incorporates flow limitation so that it can be set for required maximum flow in the riser.
ASV-I is supplied with rectus measuring nipples so that flow in the pipe can be measured.
ASV-I and ASV-P(V) is connected via an impulse tube, and thereby giving a constant differential pressure across the riser and ASV-I. This way it is possible to control the maximum flow for each riser, and ensuring distribution between them. |

- Easy to set, self acting flow controller
- Opens on rising differential pressure
- DN15, DN20, DN25
- Setting range of 0.05 to 0.5 bar
- Internal/External thread variants
- Improves system efficiency
- Maintains minimum flow rates through boiler and pump
- Essential in low water content boiler systems
The AVDO range of automatic bypass valves can be used as either differential pressure controls or to provide a minimum flow through a system.
Many boiler manufacturers are now insisting that a bypass be fitted in all installations to ensure that the volume of water circulating through the boiler does not fall to below a predefined
minimum, regardless of the load on the system. Recognising the energy efficiency advantage of such controls the Building Regulations now require in both new-build and boiler replacement
contexts, where a bypass is specified by the boiler manufacturer, that an automatic bypass is fitted. Automatic bypass valves improve system
efficiency by opening only when there is a need to bypass water, this usually occurs at times of part load when radiator thermostats in the system are partly closed and water flow around the boiler is restricted. In addition to ensuring adequate flow around the boiler, automatic bypass valves also prevent pump pressure from climbing
significantly above design levels, thus reducing the risk of noise in the system.
Available in a variety of sizes, the capacity of this range of valves is very high with large but linear changes in water throughput for relatively small increases in differential pressure. This
allows a 15mm valve to be used in situations where 22mm valves are normally required.
Setting Range 0.05 - 0.5 bar
Max. differential pressure 0.5 bar
Operation pressure PN 10
Max. flow temperature 120°C
Max. leakage at closed valve 50 l/h |
