Vertical stacking assembly
individual function blocks are stacked on one another like a tower ( Figure T 20 ). In this way, valves can be fitted on three or four free surfaces.
Pressure gain on continuously adjustable valves
gradient on the pressure-signal function , e.g. 2,000 bar/mA. It is crucial for the accuracy that can be achieved with a controller.
Remote control
technology systems such that the operating elements need to be operated over a greater distance. Operation can be using both hydraulic and electrical signals (remote control).
Actuation element
Component that actuates a device (e.g. valve ). This can be a lever or cam ( mechanical actuation ), a solenoid or electric motor ( electric actuation ) or a piston or cylinder ( pressure actuation ).
Shut-off valve
Valve that can shut-off the flow in both directions. In fluid technology this valve is implemented in the form of a seated valve or ball valve . The valve is actuated manually, magnetically or using a
Program module
General : A part of a program which can be delimited in terms of its allotted task or structure. A control : Consequence associated with control instructions for a self-contained application-based function
Bleed valve (Hy), exhaust valve (PN)
hydraulic fluid in a hydraulic system . The valve must be fitted at the highest point in the system and can trigger automatically or be operated manually.
Load stiffness
as possible under an external load. Load stiffness for linear drives is mostly stated in N / μm. It can be compared with spring stiffness.
Proximity switch
Switch which switches when an object is approached or left. Either inductive devices which can trigger at distances of up to 25 m are used for this purpose, or capacitive devices effective at distances
Coil impedance
impedance is a function of the frequency of the signal amplitude and other operating conditions, but it can be estimated using the Ohmic resistance and the coil inductance.
