(1) Bourdon tube pressure gauge: this gauge is the most popular for visual inspections. Its case is usually filled with glycerin to protect the gauge…
The IH servo drive pack drives the pump with an AC servo motor, and the pump supplies pressured oil bidirectionally. This results in a simple…
Nearly all types of servo valves are based on common principles. Electro-hydraulic two-stage servo valves generally operate with force feedback. Given that valve pressure drop…
A servomechanism is an automatic control system designed to operate in accordance with input control parameters. The mechanism continuously compares the input signal 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.…
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 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 are solenoid controlled pilot operated directional valves, which are made multi-functionable by granting individual poppet functions, such as directional control, flow control, and…
These valves smoothly stop actuators that have a large inertia force. When a directional control valve is closed, a relief valve at the outlet side…
