Hawe MSD4-309/C1+R

Product description

A selection of additional electronic components is available for use in hydraulic systems.

Line connectors with and without additional functions, e.g. LEDs for switching position monitoring and protective circuits. Line connectors with economy circuit, e.g. to minimise the temperature at the solenoid and to save energy.

Power supply units for installation in switch cabinets.

The final force of an actuating solenoid in an interconnected state is generally significantly higher than the force required to securely hold the valve. The final force of the solenoid after interconnecting can be reduced by decreasing the voltage applied using a so-called economy circuit. Since the heating of a solenoid increases quadratically in line with the supply voltage, this may result in a very noticeable decrease in the coil excess temperature and therefore a marked prolongation of the lifetime of the solenoids.

The economy circuit is not required for customary applications but due to the reasons mentioned can be useful for long switch-on times with only short breaks, with continuous switch-on or generally in an increased ambient temperature. The same applies if valves located directly next to each other in a directional valve block are switched on at the same time and for longer time spans. Due to the low final temperature, this generally results in increased switching reliability during switching operations at the hydraulic limits Qmax and pmax.
