These valves are a combination of a proportional electro hydraulic pilot relief valve and a pressure reducing and relieving valve. They can control hydraulic system…

These valves are a combination of a directional and flow control valve and a power amplifier. The flow rate can be controlled by changing an…

These valves consist of a proportional electro-hydraulic relief valve, a power amplifier, and a pressure sensor. They can control hydraulic system pressures proportionally to the…

These valves contain a combination of an amplifier-integrated proportional valve, pressure sensor, and displacement sensor in order to improve the functionality and ease of use.…

Figures 8.14 and 8.15 compare circuits equipped with the general hydraulic control valves and the proportional electro-hydraulic control valves. As is evident from the figures,…

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…
