Description
Precise control of heating and cooling water
The Belimo H440B control valve is specially designed for controlling, mixing, or shutting off water flows in professional HVAC installations. The valve design supports a controlled volumetric flow and, together with a suitable actuator, forms a complete control solution. The DN40 sizing makes it clear for which pipe diameter this execution is intended.
The control valve influences the water flow to a heat exchanger or terminal unit. In combination with a suitable Belimo actuator, a motorized valve solution is created for modulating or switching control.
Important features & advantages
- 2-way execution – Targeted control or shut-off of one water circuit
- DN40 – Clear sizing for connection to the relevant pipe diameter
- External thread – Practical integration into the appropriate piping or installation concept
- G 2 1/4" – Practical integration into the appropriate piping or installation concept
- PN16 – Designed for reliable operation within the specified system pressure
- ps 1600 kPa – Designed for reliable operation within the specified system pressure
