Butterfly valves from Belimo are available as classical D6..N wafer types and as D6..NL lug types. Motorised with modulating actua- tors, they offer in economic terms extremely interesting overall solu- tions for the control of small to large volumetric flows. Extremely low pressure losses ensure maximum energy efficiency, first-class product quality and intelligent actuator concepts guarantee long-term in- vestment protection. New actuator product range A wide product range of modulating actuators with torques from 18 to 3500 Nm for indoor (IP54) and outdoor (IP66/67) applications is available for the motorisation of the D6..N/D6..NL butterfly valves. Their rapid running times make for improved control quality. Special MF types make it possible to adjust the actuators onsite precisely to the respective application. With the MP types, up to eight actuators can be combined in one MP-Bus ® line and integrated in all conventional field bus systems. The cabling costs for the bus integration can be lowered by as much as 90%. Wide range of applications The butterfly valve product range D6..N/D6..NL comprises nominal diameters from DN 25 to DN 700. A practically equal percentage valve characteristic curve can be achieved in the opening range of 0°...54º. Because of the low pressure losses, consider- able energy savings can be realised in applications such as injection circuits with 2-way, open heat exchangers or in cold and hot water circuits in general. Butterfly valves and actuators also have proven the reliability of their operational safety in practice even under difficult conditions. For the user, this means: Costs can be reduced, not only with the procurement of the inexpensive butterfly valve and actuator combina- tions but also during operation! D6.. Butterfly valves.

D6..N/D6..NL flow rate characteristic curves
The S-shaped characteristic curve of the D6..N/D6..NL butterfly valve corresponds approximately to the equal percentage characteristic curve pursuant to VDI 2176. It is only in the angle of rotation range between 0°...54° that one can speak of an approximately equal percentage characteristic curve. For an opening angle of 54°, the kvs corresponds to 35% of the kv max value for a 90° opening angle. The power factor n(gl) of the equal percentage valve characteristic curve is ≈ 2.5.
The effective volumetric flow is calculated as follows:
• Open-close/modulating 24 volt: SR..-5, SR..P-R, GR..-5, GR..-7,
DGR..-7, DR..-7 and SY2..-SY5.. (available in versions -SR, -MF, -MP)
• Open-close/modulating 230 volt: SR..-5, SR..P-R, DGR..-7, DR..-7 and SY2..-SY12.. (available in versions -SR, -MF)
Actuator specifications
• SR types: not parameterisable
• MF types: Angle of rotation, running time (excluding SY..) and control and position feedback signal can be adjusted individually on-site
• MP types: Linkage possible with all conventional field bus systems, parameterisable the same as MF types
1) Spring-return actuator SRF.. with degree of protection IP54 available2) SRQ..-5 fast runners: DN 80 with ∆ ps 200 kPa, < DN 65 with ∆ ps 1200 kPa3) Butterfly valve-actuator combinations starting with DN 400 are shipped pre-mounted only. Because the mounting kit is installed automatically,
it does not need to be ordered separately in addition.
Manually operated shut-off valves, comprised of D6.. butterfly valves + ZD6N-H.. lever or ZD6N-S.. worm gear are also available. Please contact

A wide product range of actuators and adapters is available for the motorisation of third-party valves. Various types of actuation such as open-close, modulating or multifunctional (MF) are as readily available as are versions for extreme environmental conditions.
