An energy harvester valve, also known as a generator valve, is an advanced hydraulic component named for its ability to “harvest” energy from movement or pressure fluctuations within a hydraulic system and convert that energy into electrical power. The valve utilizes the hydraulic force present in the system’s flow or pressure cycles to generate electricity, which can be used to power sensors, instrumentation, or other electronics without the need for an external power source. The ENERGEN™ energy harvester valve from Sun Hydraulics is an example of such a valve, combining smart technology with high operational reliability. It enables power generation in a cartridge valve format and can supply power to sensors, solenoid valves, and other electronics. Additionally, it is especially suited for generating power for attachments or implements where wiring may be prone to damage, thereby improving both reliability and safety.
This valve is a 2 port cartridge designed to convert hydraulic power from your application into electrical power. The valve accepts flow from Port 1 to Port 2 and outputs a 3-phase AC voltage signal.
Energy harvester valves are particularly valuable in hydraulic applications where access to electrical power is limited or where installing cables and batteries is impractical and costly. By harvesting energy directly from the hydraulic pressure cycles and flow, these valves enable self-sufficient system solutions that reduce maintenance needs and battery replacements while improving overall system efficiency. This leads to more sustainable operation and lowers the risk of downtime, especially in harsh and remote environments where servicing is challenging.
Energy harvester valves are commonly used in industrial hydraulics, mobile hydraulic machinery, and remote monitoring applications where reliable power supply to electronics is critical. They are ideal in environments where traditional power supply installation or maintenance is difficult, such as forestry, construction equipment, agricultural machinery, and other mobile applications. Thanks to their robust design and ability to continuously generate energy from system movements, energy harvester valves contribute to smarter, more efficient, and more self-sufficient hydraulic solutions.
