4 Characterised Control Valve An ordinary Ball Valve is unsuitable as a control device % Flow rate ypical heat exchanger characteristic Resultant thermal capacity Equal-percentage characteristic Amount of opening % 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 described 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. Characteristic of an ideal Control Valve % Resultant thermal capacity Flow characteristic Ordinary Ball 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 Inadequate flow control in the part-load range Flow rate Amount of opening % Characteristic of an ordinary Ball Valve Belimo has added control to the Ball Valve % Flow rate ypical heat exchanger characteristic Resultant thermal capacity Belimo Characterised Control Valve Equal-percentage characteristic Amount of opening % 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 Characterised Control Valve converts the valve s characteristic to the equal-percentage kind. he side of the characterising 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 characterising 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 valve size is also available with wide choices of different Kvs values. Characteristic of the Belimo CCV Advantages of the Belimo Characterised Control Valve 4 Characterising disc Equal-percentage characteristic No initial jump in flow on opening Excellent stability of control thanks to the characterising disc Kvs values similar to those of Globe Valves of comparable size Fewer pipe reducers needed High rangeability High close-off pressure ight-sealing

44 GRKU..-7 Electronic Fail-Safe Rotary Actuators Safety notes he actuator is not allowed to be used outside the specified field of application, especially in aircraft or in any other airborne means of transport. It may only be installed by suitably trained personnel. Any legal regulations or regulations issued by authorities must be observed during assembly. he device may only be opened at the manufacturer s factory. It does not contain any parts that can be replaced or repaired by the user. he cable must not be removed from the device. he device contains electrical and electronic components and is not permitted to be disposed of as household refuse. All locally valid regulations and requirements must be observed. Product features Mode of operation Pre-charging time (start up) ypical pre-charging times he actuator moves the valve to the position at the same time as the intergrated capacitors are loaded. Interrupting the supply voltage causes the valve to be rotated back into emergency setting position by means of stored electrical energy. GRKU24-MF-7 is controlled by a standard signal DC 2()...V and travels to the position defined by the signal. he measuring voltage U serves for the electrical display of the valve position...%. he capacitor actuators require a pre-charging time. his time is used for charging the capacitors up to a usable voltage level. his ensures that, in the event of a voltage interruption, the actuator can be moved at any time from its current position into the preset emergency setting position (POP). he duration of the pre-charging time depends mainly on the following factors: Duration of the voltage interruption PF delay time (bridging time) 3 25 PF delay s 3 25 PF delay [s] Duration of voltage interruption [Days] Pre-charging time [s] s 2s s Pre-charging time[s] Duration of voltage interruption [Days] Calculation example: In the event of a voltage interruption of 3 days and a set bridging time (PF) of 5s, the actuator requires a pre-charging time of 4s after the voltage has been reconnected. Delivery condition (capacitors) he actuator is completely discharged after delivery from the factory, which is why the actuator requires approximately 2s pre-charging time before initial commissioning in order to bring the capacitors up to the required voltage level. High functional reliability he actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached. Home position / Start he angle of rotation of the actuator is set ex-works to After the supply voltage has been applied, the actuator moves into the position defined by the control signal. 44

45 GRKU..-7 Electronic Fail-Safe Rotary Actuators Product features (continued) Emergency setting position (POP) rotary button Settings he Emergency setting position rotary button can be used to adjust the desired emergency setting position (POP) between and % in % increments. he rotary button applies only to the adapted angle of rotation range of between 3 and 95. No minimum or maximum set values are taken into account. In the event of a voltage interruption, the actuator will move into the selected emergency setting position, taking into account the bridging time. he rotary button must be set to the ool position for retroactive settings of the emergency setting position with PC-ool V3.5 or upper. Once the rotary button is set back to the range %, the manually set value will have positioning authority. Bridging time (PF) Voltage interruptions can be bridged up to a maximum of s. In the event of a voltage interruption, the actuator will remain stationary in accordance with the set bridging time. If the voltage interruption is greater than the set bridging time, then the actuator will move into the selected emergency setting position (POP). he bridging time set ex-works is 2s. his can be modified at the site of operations with the use of PC-ool V3.5 or upper. Settings he rotary button must not be set to the ool position Only the values need to be entered for retroactive adjustments of the bridging time with PC- ool V3.5 or upper.

Recommended straight pipe installation It is a general recommendation to keep minimum 2xDN of straight piping distance before the CCV installation in the pipe, to perform the best control function.for the outlet side of the CCV, there is no requirement to keep the minimum distance of straight pipe. 2 x DN Recommended mounting positions he Ball Valves can be mounted vertically (Fig. ) or horizontally (Fig. 2). However, mounting the Ball Valves with the spindle pointing downwards, i.e. upside down (Fig. 3), is not recommended. Fig. Fig.2 Fig.3 No special tools are needed for assembly. 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. 5

53 Notes on maintenance and project design Maintenance Ball Valves and Rotary Actuators are both maintenance 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 to cool down first if necessary and reduce the pressure in the system to atmospheric). Project design Installing R2..AC, R6..AO CCV, 2-way he R2.. Characterised Control Valve is a throttling device, 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..AC CCV, 3-way he R3..AC Characterised 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 he systems must not be returned to service until the Ball Valve and the Actuator have been properly re-installed and connected and the pipe work has been refilled in the proper manner. Subsequent removal In the case of applications where subsequent removal of Ball Valve will be necessary, it is advisable to make appropriate preparations beforehand. 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 VDI235 must be adhered to. Dirt filters recommended Characterised 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. 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. 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 (Characterised Control Valve and Rotary Actuator) achieves a long service life, it is essential for the valve to be rated for the correct differential pressure P V 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.
