  • Journal of Spacecraft and Rockets > Study of a fluid-controlled solid rocket motor for a Mars orbiter
    The hy- draulic actuators are controlled by a four-way, two-position servovalve (Cadillac Gage Corp.), and oil is admitted to the pressure regulator through a bank of five SieBelAir valves serving isolation and control functions generically similar to the oxidizer system.
  • Springer Handbook of Robotics
    The hydraulic power unit consists of a battery-powered direct-current (DC) motor, pump, and accumulator. A bank of servo- valves drives the actuators at the knee and hip.
  • First Emergency Shutdown Valve, Norwegian Sector
    The accumulator bank has capacity for two valve openings without being re-charged by the pumps. The use of parallel lines In the umbilical makes it possible to circulate out the hydraulic fluid in the umbilical and actuator .
  • Industrial Automation: Hands-On > Components and Hardware
    Most automated systems tend to use banks of 5/2 and 5/3 valves with open or blocked centers, depending on whether it is desirable to be able to move the actuator by hand in the deenergized state or not. … and a wide range of tubing and hoses are necessary to complete a pneumatic or hydraulic system.
  • Size reduction machine
    The control unit utilizes a bank of proportional valves , to allow feathering of the hydraulic components. An electronic control valve for each motor and actuator are mounted with the pumps.
  • Challenges Associated with HPHT Intervention Equipment
    The main valves are reinforced spring actuators beefed up to cut wireline or braided cable regardless of internal bore pressure. The control system is an electro- hydraulic MUX control system combined with a bank of 30 hydraulic accumulator bottles for local, quick hydraulic power to actuate valves and rams.
