2. Introduction Ballorex Delta DHC Differential Pressure Control Valve (DPCV) DN 15-150 1/2-2 2.1 Description The Ballorex Delta DHC is a differential pressure control valve. typically used in district heating and district cooling applications. Ensuring a constant differential pressure across motorized valves or static balancing valves. the Ballorex Delta DHC provides conditions for achieving the correct system distribution. The Ballorex Delta DHC valve eliminates at the same time any noise nuisance caused by high differential pressure across two-way control valves. static valves. or other system components. 2.2 Benefits Wide setting range for different applications: 20-80. 50-150. 100-250. 200-500 System balance ensured regardless of pressure fluctuations Noise problems eliminated Direct installation onto bends and reducers for improved flexibility Robust construction for pressure class PN16 Accurate and easy setting of designed in combination with the Ballorex Venturi or Ballorex Vario Possible to do project handovers in stages due to zone balancing Partial close-downs possible without influencing other parts of the system Easy commissioning saves time and money No overs and unnecessary energy consumption for better thermal comfort 6

2.3 Design The Ballorex Delta DHC is installed either in the supply or the return line. The supply line pressure is received above the diaphragm and the return line pressure underneath the diaphragm. through capillary tubes. One capillary tube is to be connected to the drain of a partner valve like the Ballorex Venturi. Ballorex Vario. or Ballorex Basic. and the other capillary tube to a T-piece. When pressure increases in the system. it also increases above the Ballorex Delta DHC actuator diaphragm. This forces the valve cone downwards. and the valve gradually closes. As a result. a constant pressure drop is obtained across the circuit controlled by the Ballorex Delta DHC. The DN 15-80 valves are single seated. whereas the DN 100-150 valves are double seated. The medium pressure acts onto the bottom and top surfaces of the cone at the same time. In this way. the forces produced by the medium pressure on the cone are compensated the valve cone is pressure balanced. Without the actuator the valve is held in an open position by means of a spring. With force applied on the spindle the valve will close. 7 6 5 4 3 2 1 14 12 11 13 10 9 10 15 16 9 17 8 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 - Capillary tube connection - Higher pressure diaphragm chamber - Diaphragm housing - Lower pressure diaphragm chamber - Spring - wheel - Spindle - Valve housing - Valve cone - Locking ring - Nut - Stud bolt - Gasket - Gasket for actuator - Disc - Spring - Valve seat 7

2. Introduction 2.4 Pressure balancing The Ballorex Delta DHC valve is provided with a selection of actuators for different pressure ranges. Depending on the actuator type the Ballorex Delta DHC is factory pre-set at: 50 - actuator 20-80 for DN 15-150 75 - actuator 50-150 for DN 15-150 175 - actuator 100-250 for DN 15-150 350 - actuator 200-500 for DN 15-150 The Ballorex Delta DHC valve is set to a required differential pressure by means of the regulating wheel and a setting tool. By rotating the regulating wheel with a setting tool. any differential pressure. within the control range of each actuator. can be provided. 2.5 With partner valve The Ballorex Delta DHC can be used in combination with a Ballorex Venturi. a Ballorex Vario. or a Ballorex Basic. with drain. as a partner valve. In this case one capillary tube is connected to the coupling installed on the drain of the partner valve and the other to a T-piece in the system. Ballorex Delta DHC in combination with Ballorex Venturi as a partner valve. 8

The pre-setting of the differential pressure is done by rotating the regulating wheel in the Ballorex Delta DHC. The design is set on the Ballorex Venturi or Ballorex Vario using an Allen key. The Ballorex Delta DHC valve can be installed in the return line. The pressure loss across the Ballorex Venturi partner valve, installed in the supply line, is added to the pressure loss in the controlled circuit. When the Ballorex Venturi is installed in the supply line as a partner valve. it is always in the circuit controlled by the Ballorex Delta DHC. In this instance the pressure loss across the Ballorex Venturi is added to the pressure loss in the controlled circuit and needs to be taken into account when setting the Ballorex Delta DHC valve. The Ballorex Delta DHC can be installed in the supply line. The pressure loss across the Ballorex Venturi (partner valve) installed in the return line is not added to the pressure loss in the controlled circuit. When the Ballorex Venturi is installed in the return line and is used as a partner valve it is not in the circuit controlled by the Ballorex Delta DHC valve. Consequently the pressure loss is not taken into account when setting the Ballorex Delta DHC valve installed in the supply line. When the Ballorex Delta DHC valve is installed in combination with a Ballorex Vario or a Ballorex Basic. the pressure loss across the partner valve is not added to the pressure loss in the controlled circuit. provided that the capillary tube is connected to the drain on the outlet side of the partner valve. If the capillary tube is connected to the drain on the inlet side to the partner valve. the pressure loss must be taken into account when setting the Ballorex Delta DHC (see the application examples 5 and 6 for further details). 9

2. Introduction 2.6 Mounting An arrow on the Ballorex Delta DHC valve housing indicates the direction to be respected. The Ballorex Delta DHC can be installed in the return or the supply line. No straight piping before and after the Ballorex Delta DHC is required. The valve can be installed directly at bends. System flushing and pressure testing can be done when the maximum differential pressure setting is provided on the actuator. Maximum test pressure is 16 bar. It is extremely important that both sides of the rubber diaphragm in the actuator are filled with media before start up. If only media has been filled on the upper chamber the pressure can cause severe damage to the diaphragm. After mounting the capillary tubes, the diaphragm chamber has to be vented by loosening the connectors of the capillary tubes. When air is bled and water starts dripping from the capillary tubes, the connectors are tightened. The capillary tubes are to be connected in such a manner that the highest pressure (forward ) is always connected to the diaphragm side where the differential pressure adjustment is made (lower chamber). The lowest pressure (return) is always to be connected to the diaphragm side closest to the valve. To provide the required setting of the Ballorex Delta DHC, the pre-setting wheel is rotated using the setting tool. The differential pressure stabilized by the Ballorex Delta DHC can be verified with the Ballorex Balancing Computer BC2. After connecting one hose to the high pressure port on the Ballorex Venturi (if it is used as a partner valve) and the other hose to the drain valve (provided as an accessory and installed in a T-piece), the Ballorex Balancing Computer BC2 will display the pressure drop in the controlled part of the system. Differential pressure verification is also possible when the Ballorex Delta DHC is combined with the Ballorex Vario or the Ballorex Basic. It is recommended to install isolation valves to be able to service the controlled circuit. During the start-up isolation valves are opened simultaneously slowly and carefully in order to put pressure on both sides of the diaphragm. It is very important to not only put pressure on one side at a time because this will destroy the diaphragm. The differential pressure across the diaphragm must never exceed the set point pressure. 10

2.7 Operation The Ballorex Delta DHC valve is designed for district heating and district cooling systems to ensure a constant differential pressure across the motorized valve controlling through the heat exchanger or in a direct heating system. The stabilization of the differential pressure across the motorized valve improves the temperature control function. The motorized valve opens or closes only in response to the temperature signal from the controlled system and not because of the pressure fluctuation that would trigger changes. The Ballorex Delta DHC provides a constant differential pressure across a motorized valve at a heat exchanger. When the Ballorex Delta DHC is combined with a Ballorex Venturi or a Ballorex Vario. the solution can be used as both a constant pressure regulator and as a maximum limiter. This guarantees that the designed is never exceeded and that the motorized valve is operating with the required authority to provide optimal temperature control. The Ballorex Delta DHC provides a constant differential pressure across a motorized valve in a direct heating system. The Ballorex Delta DHC can be also combined with the Ballorex Basic to ensure constant differential pressure across the motorized valve and to be able to service the controlled part of the system or circuit. The Ballorex Basic can be used for verification provided that the pressure loss across the measuring points of this valve is at least 3.0. When the motorized valve is in a fully open position and the pressure loss across the measuring points of the Ballorex Basic is at least 3.0. the designed can be adjusted by providing the required differential pressure setting on the Ballorex Delta DHC. The motorized valve needs to be correctly sized for this application to operate with the desired authority. 11

3. Applications Application 1 - Temperature control in a heating system with air handling units The Ballorex Delta DHC installed at a heat exchanger in a central heating system will stabilize the differential pressure across the motorized valve. As a result the motorized valve only reacts to the temperature signal and not to pressure fluctuations. The Ballorex Venturi is used as a partner valve to connect the capillary tube and to limit the maximum. The pressure loss across the Ballorex Venturi needs to be taken into account when setting the Ballorex Delta DHC. Application 2 - Temperature control in an air-condition cooling system The Ballorex Delta DHC installed directly in a cooling system will stabilize the differential pressure. By providing stable working conditions the motorized valve only reacts to the temperature signal and not to pressure fluctuations. The Ballorex Venturi is used as a partner valve to connect the capillary tube and to limit the maximum. The pressure loss across the Ballorex Venturi needs to be taken into account when setting the Ballorex Delta DHC. 12

Application 3 - Temperature control in a domestic water system The Ballorex Delta DHC is installed on the primary side of a domestic water system. By stabilizing the differential pressure the desired working conditions for the motorized valve are ensured. The Ballorex Basic can be used as a partner valve to measure the. During commissioning the motorized valve is in a fully open position. When the pressure loss across the measuring points of the Ballorex Basic is at least 3.0, the designed can be verified and adjusted by providing the required differential pressure setting on the Ballorex Delta DHC valve. Application 4 - By-pass across a pump The Ballorex Delta DHC can be used in the pump by-pass (or across supply and return pipes of a circuit). This prevents the pump working against a dead head when all the sub-circuits are closed down. Note: For this application the Ballorex Delta DHC with reverse acting valve needs to be ordered. The valve is provided on request only! 13

3. Applications Application 5 - Ballorex Delta DHC in combination with Ballorex Vario or Ballorex Basic When the Ballorex Vario or the Ballorex Basic is used as a partner valve to the Ballorex Delta DHC, the capillary tube must be connected to the drain installed in the P/T port on the outlet side of the valve. In this instance the pressure loss across the partner valve is not added to the pressure loss in the controlled circuit and thus the Ballorex Delta DHC setting must be equal to the differential pressure required for the controlled circuit only. ΔPdHc = ΔPc Application 6 - Ballorex Delta DHC in combination with Ballorex Vario or Ballorex Basic When the Ballorex Vario or the Ballorex Basic is used as a partner valve to the Ballorex Delta DHC, the capillary tube must be connected to the drain installed in the P/T port on the inlet side of the valve. In this instance the pressure loss across the partner valve is added to the pressure loss in the controlled circuit and the Ballorex Delta DHC setting must be equal to the differential pressure required for the controlled circuit and the pressure loss across the partner valve. ΔPdHc = ΔPc + ΔPbv 14

Product data sheet The Ballorex Delta DHC DN 150 can be combined with the Ballorex Venturi DN 150-300 to provide a constant differential pressure in the controlled part of the system as well as to ensure the option of limiting the maximum. See the application examples for further details.

4.5 Valve setting DN 15-150 The Ballorex Delta DHC valve is provided with four differential pressure setting ranges. The differential pressure setting is done turning a regulating wheel operated by a setting tool. Differential pressure setting range Factory setting 20-80 50 50-150 75 100-250 175 200-500 350 Other settingsfactory setting To provide any other setting on the Ballorex Delta DHC valve, the regulating wheel must be rotated using a setting tool. The rotations of the regulating wheel change the spring compression and thus the force counteracting the force produced by the pressure in the membrane chamber. Each time the regulating wheel is rotated, a new force equilibrium is obtained ensuring the desired differential pressure in the controlled circuit. In order to control the setting, pressure gauges must be installed in the supply and the return lines. The differential pressure can be also checked with the Ballorex Balancing Computer BC2 provided that the medium temperature does not exceed 90 C. The balancing computer must be connected to the measuring point on a partner valve and to a measuring point installed in the pipe inside the controlled loop of the Ballorex Delta DHC valve. The Ballorex Delta DHC is provided with two capillary tubes for installation in the supply or the return line. The valve does not provide the shut-off function. It is therefore recommended to install isolation valves in the system. 59
