Bar
Unit for pressure: 1 bar = 105 N/m2 The unit "bar" is frequently used in modern fluid technology, as that way the traditional numerical values can still be used for pressures. In SI units the unit "pa
Mounting subplate
Plate on which the valve is fastened. It contains the bores necessary for the function of the valve and is connected to the pipes. There are different types: Single port mounting subplates: These are
Analogue measuring technology
Recording or acquisition of measured variables using analogue measuring instruments. The measured value is represented continuously and with the correct magnitude.
Pressure-reducing valve (pressure control valve)
Valve that keeps the (lower) outlet pressure (secondary pressure) p 2 constant even with changing inlet pressure (primary pressure) p 1 . This action is achieved by a valve cone, held open by a spring
Sequence of measurements
A sequence of several measurements at the same object.
Linearity
A transfer element may be referred to as linear if the law of superposition (superposition principle) applies. Linear elements may therefore be split into parallel elements whose output signals are ad
Leakage line
Line which returns leaked fluid to the container. Its dimensions should ensure this is possible at all times with hardly any pressure — even at low temperatures.
Rapid traverse circuits
Measures for quickly moving the tool to its working position. These include, among others The plunger circuit for fast advance , Usage of high volume low-pressure pumps (Figure E 3 a) , Rapid traverse
Force multiplication ratio
Since the pressure in a fluid is the same at every point (laws of hydraulics), the force generated is solely dependent on the size of the area on which the pressure is acting. It is possible therefore
