At Hewa you will find valves for ALPS EXCLUSIVE ARTIC and URBAN LINE heat pumps. This category is intended for installers, service technicians and technical buyers looking for a suitable valve for service, fault diagnosis, maintenance or replacement.
A valve affects control, flow, pressure build-up and operation of the heat pump system. Always check the exact heat pump model, article number, EAN, connection, valve type and technical version before ordering or installing a valve.
Valves for ALPS EXCLUSIVE ARTIC and URBAN LINE heat pumps
Valves are used in compatible ALPS EXCLUSIVE ARTIC and URBAN LINE heat pumps to regulate, switch or shut off water-side circuits. Depending on the technical configuration, a valve may be part of the hydraulic control system, the switching between operating functions or the safety operation of the installation.
During service, maintenance or replacement, the valve must match the exact heat pump configuration. The correct spare part depends on the series, unit type, article number, connection, voltage of any actuator, mounting position and technical specifications of the system.
Important checks for a valve
- Check whether the valve is suitable for the relevant ALPS EXCLUSIVE ARTIC or URBAN LINE heat pump.
- Always compare the article number, connection, flow passage, thread connection, sealing and mounting position with the original component.
- Check whether the valve moves smoothly and is not blocked by contamination, scale build-up, wear or internal damage.
- Look for leakage, insufficient flow, fault codes, pressure differences or a system that does not switch correctly.
- For electrically controlled valves, also check the valve motor, connector, cable, voltage and PCB control signal.
Application, replacement and technical attention points
A valve may need to be replaced in case of leakage, mechanical blockage, incorrect flow, worn sealing or faults in hydraulic switching. If the heat pump no longer switches correctly between heating, cooling or domestic hot water production, the valve should also be inspected.
Work on hydraulic, electrical or refrigeration-related components must be carried out by a qualified technician. After replacement, the mounting position, flow direction, system pressure, air bleeding, water quality, electrical control and any controller fault messages should be checked.
Frequently asked questions about valves
What is a valve used for in a heat pump?
A valve regulates, opens, closes or switches a water-side circuit in the heat pump installation. The component can affect heating, cooling, domestic hot water production, flow rate and correct hydraulic control.
When should a valve be replaced?
Replacement may be required in case of leakage, blockage, insufficient flow, damaged seals, internal contamination or when the heat pump no longer switches correctly between different operating modes.
Does every valve fit every ALPS EXCLUSIVE heat pump?
No, the correct version depends on the series, unit type, article number, connection, mounting position and technical configuration. Always compare the valve with the original component before ordering or installation.
Should the valve motor also be checked?
Yes, for electrically controlled valves, the fault may be in the valve itself, but also in the valve motor, cable, connector or PCB control signal. The complete control section should therefore always be checked.
Can a valve be replaced without technical inspection?
No, a valve must be technically checked for connection, flow direction, sealing, operation and compatibility. Installation and diagnosis must be carried out by a qualified technician.
