Control Valves
DANFOSS MOTORIZED CONTROL VALVE
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.
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:
- Easy selection, installation, commissioning and maintenance mean less time, money and effort
- Excellent control performance, even in the most demanding systems
- Increased reliability and operational safety due to built-in thermic and overload protection of the electromotor.
DANFOSS ROTARY VALVES
Danfoss Rotary valves are used in heating systems that include:
- Boiler applications
- Solar applications
- Heat pump applications
- Mixing and diverting applications
- Priority control applications
- Rotary valves are designed for regulation of flow and temperature in heating system that can accept a certain leakage and where a defined control characteristic is not required.
- Danfoss has designed the unique position indicator for easier installation and simple commissioning. The valve position indicators are designed to be viewed from the top or from the side, with or without the actuator mounted. This saves time during installation and commissioning.
- Due to the new advanced valve design, Danfoss rotary valves have the lowest leakage in their class. For zero leakage and premium controllability, Danfoss recommends iMCV™ – the new generation of intelligent motorized control valves. iMCV™ includes an anti-oscillation function, tool-free installation, one actuator for DN 15 to 80 and bubble-tight design (no leakage).
Features and benefits:
- Lowest leakage in class, unique adjustable position indication for faster commissioning and easy installation
- AMB actuators are faster, maintenance-free and flexible: the best quality actuators on the market.
- 100% bullet-proof commissioning with visible valve position indicator.
HONEYWELL WATERFLOW SWITCH WFS 6000
Honeywell provides WFS series water flow switches which have been designed to provide excellent performance where accuracy, reliability, and rugged construction are required. These flow switches are used in liquid flow lines carrying water or any fluid neither harmful to brass and phosphor bronze nor classified as a hazardous fluids. They can be wired to close one circuit and open a second circuit when liquid flow either exceeds or drops below the adjusted flow rate. The WFS series are recommended for liquid pressure and temperature as mentioned below and must not be used on lines carrying liquids below 0C.
Features and benefits:
- These series may be used on liquids with high salt or chlorine content.
- They may be also used outdoors.
- They are designed for use only as operating controls.
