■ The heart: the central HVAC plantWhether they operate with water, steam or heat transfer oils, central HVAC plants are used to generate and distribute heating and cooling energy to maintain comfortable temperatures in buildings, zones and rooms. They consist of primary plants for heating, cooling, ventilation and air conditioning as well as of distri-bution networks in buildings and district heating/cooling systems. Acvatix valves and actuators ensure energy-effi cient operation for optimum comfort in all operating and load situations.

■ Everything for high energy effi ciencyAcvatix helps to ensure that buildings achieve the highest energy effi ciency classes according to the European Norm EN 15232 (energy performance of build-ings).

This means you can design your plant optimally in terms of hydraulics and control thanks to the fi nely graduated range – also for part load behavior such as summer/winter or day/night operation. This reduces energy consumption and thus operating costs.

In addition, actuators with very short positioning times optimize the energy effi ciency in fast controlled systems, in controlled systems with a high degree of diffi culty, or in plants with very dy-namic plate heat exchangers. The electro-hydraulic actuators control very high dif fer ential pressures and large volumetric fl ows using little energy. And the high-precision, fast-acting valves with mag-netic actuator save energy particularly in chilled water plants.

Acvatix for central HVAC plants ■ Your variety for energy generation and distribution

Acvatix offers you all types of valves and actuators required for central HVAC plants. The range includes 2-port and 3-port valves with fl anged or threaded connections and butterfl y valves – com-bined with actuators that can be driven by all room and building automation con-trollers. The valves are suited for open and closed circuits with water, water with anti-freeze, drinking water, steam and other media.

This means that with Acvatix, you can im- plement all control, shutoff and change-over functions in HVAC and drinking water plants, whether simple, small, large or complex.

■ Investments that pay off in the long term

Due to their rugged design and manufac-ture according to international produc-tion and testing standards, Acvatix valves and actuators have a particularly long service life. Thanks to their backward compatibility, they can be simply replaced with new products even after decades of operation.

And that pays off also: Various auxiliary functions are available to increase the protection of plants and buildings, such as an integrated fail safe function in the event of a power failure, or position feed-back and connection options for frost protection devices, for example.

■ Convenient functions for any situation

Based on the integrated position feed-back of the actuators, plants can be monitored effi ciently and faults rectifi ed quickly. If individual plant components fail, the supply of heating or cooling energy can still be ensured thanks to convenient manual operation.

■ Designed for installers and users With Acvatix you benefi t from ease of service and installation. You can simply and cost-effi ciently install and commission the actuators. The freedom from main-tenance minimizes effort and operating costs. And manual operation with no need for additional tools assists you not only during commissioning, but also in unforeseen operating situations.

■ Designed for the environmentThe Acvatix range also meets the most demanding requirements with respect to the environment, which the ISO 14000 certifi cation verifi es. The environmen-tal friendliness of Acvatix ranges from environmentally sound development and production in accordance with the Siemens standard SN 36350 and current environmental standards, such as RoHS and WEEE, to the possibility of environ-mentally compatible disposal.

■ On-site control: room and zone applications

The room and zone controllers ensure comfort in individual living and working spaces in all operating situations. Quiet, fast-acting and accurate valves and actuators are necessary to minimize tem-perature fl uctuations and to save energy.

■ A wide selection for various combinations

The Acvatix range can be combined in a number of ways, making a signifi cant contribution to optimum room and zone control. The products range from the high-performance models of the Elite line to radiator valves. They can be combined with thermostatic, thermal or electromo-toric actuators. The recommended device combinations for the corresponding appli-cations were all tested in the lab and in the fi eld for their suitability and control performance.

■ Just save energy – room by room, zone by zone

With the extensive product range, you can optimally design room and zone applications with hydraulics and control, saving energy and costs.

MiniCombiValves and combi valves combine three functions: a control valve for controlling the volumetric fl ow, an adjusting mechanism for a presettable volumetric fl ow and a differential pressure controller for balancing pressure fl uctu-ations in the hydraulic system. They alsoensure load-independent, automatic hydraulic balancing of heating and venti-lation plants. What’s more, they prevent rooms and zones from over- or under-supply, enhance comfort and allow par-ticularly energy-effi cient applications.

In addition, valve characteristics for linear or continuous supply of heating and cool-ing energy via air heating and air cooling coils contribute to energy effi ciency.

■ Products with long-term investment protection

When you select valves and actuators for room and zone applications, you rely on rugged products manufactured according to strict quality guidelines that ensure a long service life and reliable operation. They meet European and international standards, such as eu.bac and EN 215. Thanks to backward compatibility, the products can be replaced seamlessly even after many years of operation.

■ Intelligent comfort when it mattersQuiet operation and fast and accurate control ensure optimum comfort.

■ Practical in every respectWith Acvatix you show your sense of re-sponsibility for the environment through the environmentally compatible and re cyclable materials used in accordance with Siemens norms. The product range also includes actuators with halogen-free cables that act fl ame-retardant in case of a fi re and avoid the emission of toxic gases. That reduces the risk for people and the environment. Naturally, the valves and actuators for room and zone appli-cations are also developed and produced in compliance with environmental stan-dards such as RoHS.

Furthermore, you benefi t from practical handling and freedom from maintenance. The products can be installed and com-missioned quickly with little effort.

The combi valves VPI45.. combine three functions: a control valve [3] for controlling the temper-ature (via the room controller), an adjusting mechanism [2] with a scale for a presettable volumetric flow, a differential pressure con-troller [4] for balancing pressure fluctuations in the hydraulic system or across the control valve. The mechanical series-connected differ-ential pressure controller keeps the differential pressure (p

1 – p

2) constant across the valve

and thus the set volumetric flow also. The de-sired maximum volumetric flow can be set with the adjusting mechanism [2]. The room controller (not shown) provides constant temperature control together with the SSD.. actuators. The VPI45..Q combi valves have pressure test points (P+, P-) for measuring and monitoring the differential pressure across the valve during commissioning.

■ Diverse choices for the supply and distribution of cooling energy or heat recovery

Acvatix offers you hermetically sealed mixing, diverting and 2-port valves for refrigeration plants. These include re-frigerant valves for expansion, hot-gas and suction throttle applications. All valves are compatible with stan dard con-troller signals 1) and operating voltages AC 24 V or DC 20...30 V.

■ Greater energy effi ciency for refrigeration systems

All Acvatix refrigerant valves save energy in the refrigeration plant, for example through their accurate superheat control also in part load situations. In addition, the fi ne stroke resolution enables exact positioning and thus accurate and effi cient energy control. Thanks to the positioning time of less than one second, you can handle even the most diffi cult control tasks reliably while saving energy.

■ Benefi t from your investments in the long term

Rugged, long-lasting and backward-compatible, the Acvatix refrigerant valves pay off for the long term. Their high effi -ciency and hermetic sealing reduce the amount of refrigerant, the plant size and thus the investment costs. Integrated functions provide added value by protect-ing the refrigeration plants and buildings.

For instance, automatic, fast shutoff in the event of a power failure prevents the temperature and pressure from reaching excessive levels – a safety function that products of other manufacturers can only ensure with additional plant components.

■ Features for various comfort options and customer benefi ts

To ensure that dynamic processes in refrig-eration plants can be handled optimally with small amounts of refrigerants, all 2-port refrigerant valves have an integrated high-precision position controller with a stroke resolution of 1:1000.

■ Simple and environmentally friendlyThe refrigerant valves are not only simple to install and maintenance-free, but also environmentally compatible: In all actu-ators the core is completely surrounded by a pressure tube. The magnet coil is located outside the refrigerant circuit, therefore the system is hermetically sealed. The magnet coil generates a magnetic fi eld that is transmitted through the pressure tube, causing the core to move and thus the valve to travel. Refrigerant valves from Siemens do not have static or dynamic seals that could release refrigerants into the environment in the event of damage.

Highlights

■ Hermetically sealed refrigerant valves – also in IP65 design

■ Energy savings through accurate superheat control, very fi ne stroke resolution and positioning time < 1 second

■ Long-term investment protection thanks to long service life, backward compatibility and protection functions

■ Vibration-free operation, safe in the event of a power failure, and control of dynamic processes

■ Ease of service and installation, and high degree of environmental compatibility

■ Sizing and selectionCorrectly sized and selected valves and actuators make an important contribution– to the hydraulic and thermal control

stability of HVAC plants– to optimum operation in all operating

and load situations– to the energy effi ciency of the entire

HVAC plant

■ HVAC Integrated Tool (HIT)The HVAC Integrated Tool relieves the burden on installers, consultants and planners both in routine tasks and in the time-consuming search for suitable prod-ucts for controlling a HVAC or refriger-ation system. It provides access to the ex-isting range of valves, actuators, sensors, thermostats and variable speed drives from Siemens. The self-explanatory and user-friendly menu navigation is adapted to the typical workfl ows of the industry and allows you an easy start.

In addition to the CD version, the HIT is also available as an online version 1) which looks and functions in the same way. This means that all data on the product range and all stored documents are always up-to-date. When previous projects are accessed, the program also identifi es products that are no longer available, and suitable successor models can be found immediately with the help of the search function.

■ Easy DATAUsing the Easy DATA software tool, you can quickly and easily insert valves and actu-ators into your 2D and 3D CAD plans for HVAC and refrigeration systems. Easy DATA is available on CD and also offers you prod -uct labeling, tendering texts and data sheets.

■ Valve slide rulesThe proven Acvatix valve slide rules simplify sizing and cover the selection for appli-cations with water. For central HVAC plants: 0-91826-EN, for room and zone applications: 0-91827-EN.

Highlights

■ Fast, targeted planning and design of HVAC plants thanks to HIT

■ Support in the selection of valves and actuators through HIT

■ Fast creation of 2D and 3D CAD layout plans with Easy DATA

■ Simple valve selection for water applications thanks to valve slide rules
