Part with internal and external thread to connect two with different diameters.

The density of a fluid changes with temperature and pressure. It reduces with temperature and increases with pressure (Figure D 12) . The density-pressure function is determined by, among other things [...] things, the compressibility of the fluid. With β = compression coefficient ρ o = density at atmospheric pressure p a = atmospheric pressure

Central position for valves with three switching positions . With directional valves , it is generally arranged with the help of centring springs and then becomes the initial position . Around 14 variants [...] valves, with common ones being centre position blocked; all working openings are closed ( Figure M 26 a ), open-centre position ; all working openings are connected with each other and with the process

with auxiliary energy, which amplifies the power. Example: Pneumatic pressure amplifier, electrical amplifier, for example with a signal voltage at the input and a signal current at the output with a higher

consumers; 3/3-way directional valves : As above, but with a centre position with different design forms 4/2-way directional valves : Valves with four controlled ports and two switching positions to control [...] consumer; 4/3-way directional valves : As above, but with a centre position with several design forms; 5/3-way directional valves : As above, but with two separate tank connections. The valve does not match [...] Working method : Switching directional valves (with positive or negative overlap- and continuously adjustable directional valves (with a positive, negative or zero cut overlap). Construction design : piston

and smallest values for the individual variables with which the system is allowed to be operated with other influencing variables exactly defined and with the load duration in the most extreme case (CETOP

Device which converts the electrical charge associated with a measuring instrument into a voltage signal and amplifies it in accordance with the piezoelectric effect.

Control element in directional , pressure and flow valves with a piston shape, which is generally countersunk, i.e. sealed with gap seals .

controlled hydraulically with sequential valves or electrically with process-dependent signal elements position sensors , pressure switches , timer relays ). [...] If, on drives with several loads, the function depends on reaching a specific boundary condition for the upstream load, the term sequence control is used. The sequence control of actuators can be controlled

programmed control with the feedback from the sensors in accordance with the logical instructions for control signals. This means, e.g., the linking of independent input information with machine functions
