2. the control method
YUKEN A series variable piston pumps provide a variety of control methods to meet the needs of different application scenarios. Common control methods include：
01-Pressure compensator type: Automatically adjust the flow rate according to the system pressure, keeping the set pressure unchanged.
02-Solenoid valve-Two pressure control types: the switching control of the two pressures is realized through the solenoid valve.
03-Unloading pressure compensator: When the system pressure reaches the set value, it is automatically unloaded to reduce energy consumption.
04EH-Electro-hydraulic proportional pressure and flow control type (OBE type): Precise control of pressure and flow is achieved through an electro-hydraulic proportional valve.
05-Two-pressure and two-flow control type of system pressure: it provides a combination of two pressures and two flow rates.
09-Constant power control type: Keep the output power of the pump constant, suitable for power-limited occasions.

3. Pressure adjustment range
The pressure adjustment range of YUKEN A series variable piston pumps varies from model to model. Common pressure adjustment ranges include：
B-1.2~7MPa: Suitable for low-voltage application scenarios.
C-1.2~16MPa (1.5~16MPa in A70, A90, A100, and A145): Suitable for medium voltage application scenarios.
H-1.2~21MPa (1.8~21MPa in A70, A90, A100, and A145): Suitable for high-voltage application scenarios.
K-2.0~28MPa: suitable for ultra-high pressure application scenarios.

4. the installation method and interface location
YUKEN A series variable piston pumps provide a variety of installation methods and interface locations to meet the installation needs of different equipment. Common installation methods and interface locations include：
Installation method：
Flange-mounted type (-F): It is connected to the equipment through a flange, which is suitable for occasions where stable installation is required.
Base-mounted type (-L): It is connected to the equipment through the base, which is suitable for occasions where flexible installation is required.
Interface location：
Side interface (S): The inlet and outlet of the pump are located on the side to facilitate the connection of other hydraulic components.
Axial interface (unmarked): The inlet and outlet of the pump are located in the axial direction, which is suitable for specific installation scenarios.
