Proportional hydraulics
Application of proportional hydraulics
Hydraulic equipment with proportional electric control is used for remote control of the parameters of the hydraulic drive, and is also used as links in closed-loop automatic control systems.
The kit includes a built-in or separately located electronic unit that provides coordination with the operating system, stability of the control current in the magnet winding regardless of its heating and voltage fluctuations in the network, proportional dependence of the control current on the input signal, coordination with low-power control devices and standard buses ( CAN-bus, Profibus, etc.), the possibility of a linear increase in the control current for 0.1 ... 5 s with a step input signal (ramp), regulation of the oscillation amplitude and setting the initial current (zero setting), as well as direct connection of the master resistors.
In proportional equipment, command pulse modules are used. The model demodulator processes the signal, transmits the working signal.
The "Motorimpex" product range includes a wide range of proportional control hydraulic equipment:
- directional control valves;
- relief valves;
- pressure reducing valves;
- flow regulators;
- throttles.
