4 he Belimo characterized control valve (CCV) An ordinary ball valve is unsuitable as a control device % Flow rate ypical heat exchangercharacteristic Resultant thermal capacity Equal-percentage characteristic Characteristic of an ideal control valve % Flow rate Amount of opening % Resultant thermal capacity Flow valve characteristic Ordinary ball d Amount of opening % Characteristic of an ordinary ball valve In order to ensure good stability of control, a control valve must have a flow characteristic that complements the nonlinear characteristic of the heat exchanger in the HVAC system. An equal-percentage valve characteristic is desirable in order to produce a linear relationship between the thermal output and the amount of opening of the control device. his means that the flow rate increases slowly as the valve begins to open. Characteristic in ordinary ball valves is severely distorted. he reason for this is that an ordinary ball valve has an extremely high flow coefficient (Kvs value) compared with its nominal size, several times that of a comparable globe valve. herefore, an ordinary ball valve is not very suitable for performing control functions: Quick-opening flow characteristic Flow coefficient excessive due to the design Flow control inadequate in the part-load range Belimo has added "control" to the ball valve % Flow rate Heat exchanger characteristic Resultant thermal capacity Equal-percentage characteristic Belimo characterized control Amount of opening % Characteristic of the Belimo CCV valve Belimo has succeeded in solving the problem of the distorted flow characteristic of ordinary ball valves. A so-called "characterising disc" in the inlet of the characterized control valve converts the valve's characteristic to the equal-percentage kind. he side of the characterizing disc facing the ball is concave and is in contact with the surface of the ball. hus, the actual flow is regulated by the hole in the ball and by the V-shaped aperture in the characterizing disc. he Kvs value is reduced and corresponds approximately to that of a globe valve of comparable size. In order to avoid having to fit pipe reducers in the majority of cases, each size of valve is also available with wide choices of different Kvs values. Advantages of the Belimo Characterized Control Valve Characterising disc Equal-percentage characteristic No initial jump in flow on opening Excellent stability of control thanks to the characterizing disc Kvs values comparable with those of globe valves of comparable size Fewer pipe reducers needed High rangeability High close-off pressure ight-sealing D-CCVE-3 Subject to technical changes. 4

M Angle of rotation Angle of rotation Mounting, installation and commissioning Separate supply When ball valve and rotary actuator are supplied separately, they can be assembled on-site. Recommended mounting positions he ball valves may be mounted either vertical (Fig. ) or horizontal (Fig. 2). However, mounting the ball valves with the spindle pointing downwards, i.e. upside down (Fig.3), is not recommended. No special tools are needed for assembly, and instructions will be found packed with the valve and actuator. Commissioning must not be carried out until the ball valve and rotary actuator have been assembled in accordance with the instructions. Fig. Fig. 2 Fig. 3 D-CCVE-3 Subject to technical changes. 36

37 Notes on maintenance and project design Maintenance Ball valves and rotary actuators are both main -tenance free. Before any kind of service work is carried out on control devices of this type, it is essential to isolate the actuator from the power supply (by unplugging the power lead). Any pumps in the particular part of the piping system concerned must also be switched off and the appropriate isolating fittings closed (also allow everything Project design to cool down first if necessary and reduce the pressure in the system to atmospheric). he systems must not be returned to service until the ball valve and the actuator have been properly re-installed and connected and the pipework has been refilled in the proper manner. Subsequent removal In the case of applications where subsequent removal of a ball valve will be necessary, it is advisable to make appropriate preparations before hand. A typical example is the provision of extra detachable ZR23.. pipe connectors (page 32). Disposal When a control device (ball valve and actuator) has come to the end of its service life, the two parts must be dismantled and sorted into different materials before being disposed of. Installing R2../R6.. CCV, 2-way he R2.. characterized control valve is a throttling device, so must be installed in the return line of systems in order to ensure less thermal stress on the seals of the device. he direction of flow specified must be adhered to. Installing R3.. CCV, 3-way he R3.. characterized control valve is a mixing device. Whatever type of installation is employed, it is essential to adhere to the directions of flow specified. Whether a valve is installed in the supply or the return of a system depends on the type of hydraulic circuit being employed. No balancing valve is needed in the bypass line of a diverting circuit because of the reduced flow in the bypass. Water quality requirements he water quality requirements specified in VDI 235 must be adhered to. Dirt filters recommended Characterized control valves are relatively sensitive control devices, and in order to ensure that they give long service life, the fitting of dirt filters is recommended. Sufficient isolating valves It is essential to ensure that sufficient isolating valves are provided. Correct rating and sizing In order to ensure that the control device (characterized control valve and rotary actuator) achieves a long service life, it is essential for the valve to be rated for the correct differential pressure pv across the valve, i.e. with adequate valve authority (Pv >.5). he differential pressure p v depends on the type of hydraulic circuit in which the valve is being used.
