Hydraulic Solenoid-Operated Reversing Valve Reversing Time And Frequency

1. REVERSING AND RESETTING TIME

Generally from the electromagnet energized to the spool commutation termination of the time for the commutation time of the electromagnetic reversing valve.
From the electromagnet power off to the spool back to the initial position of the time for the electromagnetic reversing valve reset time.
Usually the commutation time is not equal to the reset time.
However, it is roughly equal to
The commutation time of AC solenoid valve is about 0.01~0.03s.
DC solenoid valve reversal time is about 0.02-0.07s.

2. REVERSING FREQUENCY.

The reversing frequency of electromagnetic reversing valve refers to the number of reversing times allowed by the court in a unit of time.

The commutation frequency of the solenoid reversing valve is mainly limited by the characteristics of the solenoid, the starting current of the AC solenoid is more than 3 times higher than the normal suction current, often starting will intensify the heating of the coil.

Generally, the allowable working frequency of AC solenoid is below 60 times/min, and the heat dissipation condition of wet solenoid is better, and the reversing frequency is higher than dry type.

3. DC MAGNET

DC magnet is not limited by the starting current, the commutation frequency can be 250-300 times / min.

In addition, the commutation frequency can not exceed the limit specified by the valve commutation time

Otherwise it can not complete the complete commutation process.
