basic information

【Examples of Circuit Applications】 ■ Using a hydraulic pump to maintain cylinder pressure - Using a manual pump with V-66BR, an electric pump's solenoid valve, and a pilot check valve to maintain hydraulic pressure in the cylinder. ■ Using an air-driven hydraulic pump to maintain hydraulic pressure in multiple cylinders at different pressures for extended periods. ■ Basic valve combinations for hydraulic presses - Double-acting cylinder, VSQ-3-70, V-77 - Seat-type valve, electric hydraulic pump ■ Maintaining pressure in a single-acting cylinder for extended periods with an electric hydraulic pump - Turning the motor power of the electric pump on and off based on the set pressure of the pressure switch to maintain pressure. ■ Speed adjustment unaffected by cylinder load - Using a pressure-compensated flow control valve to adjust the cylinder speed without being affected by load. ■ Accurate hydraulic pressure adjustment via remote control - Using an electromagnetic proportional relief valve to enable precise pressure control proportional to an electrical signal from a distance from the pump, among others. *For more details, please refer to the catalog or feel free to contact us.
