Danfoss Motorized Control Valves (MCV) for district heating and cooling, HVAC and central heating systems ensure stable and accurate control of water, glycol mixtures and steam. This in turn improves temperature control and reliability while increasing the energy efficiency of the system. All of which adds up to enhanced comfort for the end-user. The MCV range comprises both regular and pressure-relieved control valves designed to operate in the most demanding applications.
Danfoss offers a comprehensive range of control valves and actuators for virtually every application: central and decentralized heating systems, domestic hot-water systems, district heating and steam.
For maximum versatility, our control valves and actuators come in different sizes, materials and connection options. They also offer a range of different functions and features to suit each specific application. With a global reputation for quality and reliability, our latest solutions are available at different price points to suit the budgetary needs of every project.
Years of customer insights and product development for district heating, HVAC and central heating applications have enabled us to create a flawless product that perfectly complies with all current requirements and future trends. Here are some of the highlights:
- Excellent control performance
The control capabilities of the MCV range are based on different characteristics, including split characteristics for DHW applications using heat exchangers, as well as linear and logarithmic characteristics. This means that even the most difficult control requirements in district heating can be met, while still providing instantaneous hot water. For DHW systems, the low slope of the split characteristic in this part of the stroke ensures stable control of the valve in the critical area near the closing position. On the other hand, the steeper part of the curve (large flow) enables fast and stable control. - Proven lifetime cost effectiveness
Thanks to easy selection, installation, commissioning and maintenance, Danfoss MCVs simply cost you less time, money and effort. - Easy handling and installation
Danfoss MCVs are easy to handle, easy to operate and easy to understand. Quick connection to actuator and valve is enabled by a threaded coupling, which also allows for rotation after mounting. External LED visualization and signaling save time and effort during installation and commissioning of MCVs. - Increased reliability and operational safety
All new products feature built-in thermic and overload protection of the electromotor. This radically reduces the risk of operational failure in either the valve or the system as a whole.
Features and benefits
