Loading…Valves
Valves for SPRSUN CGK-V2 LINE heat pumps are used in the control-related, water-side or refrigerant-related section of the system. Depending on the version, they support flow, switching, pressure balance or expansion control.
This category is intended for installers, service technicians and business customers looking for suitable valves, expansion valves or valve actuators for maintenance, diagnostics and replacement in SPRSUN heat pump systems.

Valves for SPRSUN CGK-V2 LINE heat pumps
Valves are used within SPRSUN CGK-V2 LINE heat pumps to regulate, switch or shut off water-side circuits. They affect the hydraulic operation of the heat pump and support functions such as heating, cooling, defrosting and domestic hot water operation.
The correct selection of valves and related valve actuators depends on the series, unit type, article number, connection size, voltage, mounting position, flow direction and technical configuration. Always check whether the part matches the original specifications of the unit.
Important checks for valves
- Check whether the valve or valve actuator is suitable for the relevant SPRSUN CGK-V2 LINE configuration.
- Compare the article number, connection size, connector, voltage and mounting position with the original part.
- Inspect valves for leakage, contamination, scale, damaged seals or mechanical blockage.
- For electrically controlled versions, also check the valve actuator, cable, plug connection and PCB control signal.
- Also assess water-side flow, sensor readings, pressure conditions and related control components.
Application, replacement and technical attention points
Valves may need replacement when the heat pump no longer switches correctly between operating functions, when leakage occurs or when water-side flow is restricted. In electrical versions, the cause may also be the valve actuator, wiring or control signal from the PCB.
Installation and diagnosis must be carried out by a qualified technician. After replacement, the flow direction, sealing, hydraulic function, electrical control, end position and full operation of the relevant circuit must be checked.
Frequently asked questions about valves
What are valves used for in a heat pump?
Valves regulate, switch or shut off water-side circuits within the heat pump so the system can operate correctly during heating, cooling, defrosting and domestic hot water operation.
When should valves be replaced?
Replacement is required in case of leakage, mechanical blockage, contamination, damaged sealing, incorrect flow direction or when the valve no longer switches correctly.
Does every valve fit every SPRSUN CGK-V2 LINE heat pump?
No, the correct version depends on the series, unit type, article number, connection size, voltage, mounting position, flow direction and technical configuration.
Can a fault also be caused by the valve actuator?
Yes, with electrically controlled valves a fault can also be caused by the valve actuator, wiring harness, connector, PCB or missing control signal.
Can valves be installed by the user?
Because valves are part of the hydraulic and sometimes electrical heat pump system, installation and inspection must be performed by a qualified technician.
