Amplifiers serve as a drive for the proportional electro-hydraulic control valves. They convert signal voltage from a setting adjuster to a current. Then, they amplify…
These valves accommodate flow and direction control functions for an actuator. The flow rate can be controlled by changing an input current to the solenoids…
These valves facilitate energy-saving operation of hydraulic systems by supplying the minimum pressure and flow required to drive the actuators. These valves control the pump…
These valves are flow control valves provided with a proportional DC solenoid on the restrictor. They can smoothly start, stop, and accelerate/decelerate the actuator through…
These valves consist of a proportional electro-hydraulic pilot relief valve and a pressure reducing and relieving valve. They can control the system pressure continuously through…
These valves consist of a proportional electro-hydraulic pilot relief valve and a low noise type pilot operated relief valve. They can control the system pressure…
These valves consist of a proportional DC solenoid and a direct type relief valve. Connected to the vent port of a relief valve or a…
These valves are comprised of cartridge type elements and covers with pilot passages. Although they are two-port valves designed to simply open/close the poppets according…
These valves, including the pressure control, flow control, and directional control types, have standardized mounting surfaces that conform to the ISO standards for solenoid operated…
