Sauter Control Valve 4kvs
The Sauter Control Valve 4kvs delivers continuous, reliable regulation of hot or chilled water across HVAC closed circuits, ensuring every room and zone maintains its target temperature without fluctuation or waste.
Rated at a nominal flow of 4 m³/h at a 1-bar pressure drop, this valve is engineered for accuracy where it counts most. It fine tunes water supply to individual zones, adjusts thermal capacity in secondary ventilation and heating coils, and manages localised micro circuits with the kind of stability that prevents overheating, energy loss, and uneven comfort levels. No zone receives more water than it needs,- a small detail that makes a significant difference to overall system efficiency.
Compatibility with motorised and thermal actuators, including Sauter's own system drives, enables fully automated, stepless temperature control that responds to demand in real time. Designed exclusively for treated closed circuit water systems in compliance with standards such as VDI 2035, the Sauter Control Valve 4kvs is built for professional HVAC applications where performance and reliability are non-negotiable.
Summary:
- Used to continuously regulate hot or chilled water flow in HVAC closed circuits.
- The "4 kvs" specification means the valve allows a nominal water flow rate of 4 cubic meters per hour (m³/h) with a 1-bar pressure drop across the fully open valve
- Regulates water supply to control air temperature in individual rooms or zones
- Adjusts thermal capacity in secondary ventilation and heating coils
- Manages localized micro-circuits where precise flow restriction and stable temperatures are needed
- Prevents specific zones from receiving excess water, safeguarding system energy efficiency
- Pairs with motorized or thermal actuators (such as Sauter’s system drives) to provide stepless, automated temperature control
- Designed strictly for treated closed-circuit water systems (complying with standards like VDI 2035) and is unsuitable for drinking water
Applications:
Commonly used in;
- Commercial building automation managing HVAC terminal units
- District heating & cooling lines
- Healthcare facilities
- Light industrial manufacturing
