1 Extensions to a comprehensive product range As part of our range of motorized control valves you can also find ON/OFF butterfly valves and zone valves applicable for use within heating, ventilation and air conditioning applications. Butterfly valves The Danfoss ON/OFF butterfly valves, type VFY, are wafer type valves, available in DN -00 and applicable for PN applications. The actuators are available in and 0 V AC versions. Main features: High torque transmission due to spline driven one-piece shaft Easy maintenance enabled by safety anti-blowout circlips Low closing torque due to unique rubber design Long term reliability due to self-lubricating antifriction bearings ON/OFF zone valves The range of ON/OFF zone valves, type AMZ DN - and AMZ DN -, are available as -port and -port versions for PN systems. They can be applied in connection with radiator, under floor heating or solar energy systems as well as for priority control of hot water supply and heating. Main features: The ON/OFF zone valves can be applied together with Danfoss room thermostats Compact design facilitates installation and electrical connection without opening the actuator cover Clutch assembly enables easy manual opening/closing and unlocking of the valve Due to self-cleaning effect, no disassembly of the valve is needed Automatic controls for every purpose Danfoss offers a comprehensive range of automatic controls for heating, district heating, ventilation and cooling. Along with motorized control valves our range includes electronic controllers, self-acting controllers for differential pressure, flow and temperature control, ball valves as well as heat exchangers. In addition Danfoss markets district heating substations in various sizes according to customer requirements.

3 For optimum control in any construction Your requirements have been combined with our market experience and technical knowledge to extend and innovate our product range. Danfoss markets a competitive and comprehensive range of motorized control valves with different functions and features as well as various price and value ranges. Our control valves are available in multiple sizes, different materials and with a variety of connections. The range of Danfoss motorized control valves meets the requirements of virtually every application within: Terminal & Zone Our fan coil valves for terminal and zone control, e.g. in induction units, provide stable control, consistently low noise levels and fewer fluctuations, which guarantees longer lifetime for the actuators and valves. Heating & Cooling A dedicated range of motorized control valves for water and glycol-based heating and cooling systems is available. These are typically applicable in air-handling units, water chillers, boilers and fan coils, where we can assure stable and accurate control of water flow and thereby improved comfort. District Heating As a leading supplier Danfoss markets motorized control valves optimized for district heating. These are developed especially to meet high standards for precise control of instantaneous hot water and heating supply. The valve materials and designs are highly specified for operation with high differential pressures. The range also includes actuators with DINapproved safety function. Steam For humidification, sterilisation and steam based heating systems, we offer a full range of steam valves. High temperature and pressures put heavy demands on products in steam applications, but our products are developed to withstand even the toughest conditions.

A consistently low level of noise emission is an The result is a distinctive and competitive range of important feature for control valves. Danfoss has motorized control valves, which represents progress invested substantial development resources to set in a number of essential areas and meets the increa new standards on the market in this respect. We singly stricter requirements for improved control have optimized actuator and valve operation by performance, added features and value for money. improving motor and gear technology as well as Excellent control performance valve design. Control capabilities included in the Easy handling and compact design range of motorized control valves Easy to handle, easy to operate and easy to are based on a split characteristic, understand these are distinctive properties which combines the advantages of our product range. of linear as well as logarithmic Quick and easy connection of actuator and characteristics. valve is enabled by a threaded coupling, which This means that even the most difficult control requirements in district heating can be met, while still providing instantaneous hot water. Stable control of the valve is obtained in the critical area near the closing position because of the low slope in the split characteristic in this part of the stroke. The steeper part of the characteristic (large flow), on the other hand, enables fast and stable control. also allows for rotations after mounting. Thereby cable entry on the actuator can be positioned as required. When power supply is turned on, the actuator automatically adjusts to the end-position of the valve. The movement and position of the valve are clearly displayed by the position indi cator on the actuator.
