Non heating solenoid valve has the following three advantages:

  • 1: the long heating coil without heating type will not generate heat, and the 365 circle antenna will not burn off continuously;
  • 2: power saving, equivalent to the 1/5 of ordinary solenoid valve power consumption.
  • 3: no noise, no magnetic leakage noise, more high-grade.

First, the installation and use of solenoid valve:

1, before installation, should refer to the instructions of the product, whether it meets your requirements.

2, the pipeline should be cleaned before use, the media should not be installed clean filter, to prevent impurities interfere with the normal operation of the solenoid valve.

3, solenoid valve is generally one-way work, can not be installed, the arrow on the valve is the direction of the pipeline fluid movement, must be consistent.

4, solenoid valve installed in general valve level, coil vertical upward, some products can be arbitrarily installed, but the conditions permit the best vertical, in order to increase the service life.

5. The solenoid valve should be heated or set up insulation measures when it is re working in the freezing place.

6, electromagnetic coil extraction line (connector) connection is good, should confirm whether firm, connection electrical components contact should not shake, loose will cause solenoid valve does not work.

7, continuous production of electromagnetic valve, the best use of bypass, easy maintenance, does not affect the production.

The solenoid valve 8, after a long time out, should be discharged condensate before use; wash the parts when he again according to the order of restitution installed. 9, there is an unknown place, please contact our company, for your dedicated service.

Two, solenoid valve fault and troubleshooting:

(1) the solenoid valve does not work after power on:

1, check the power wiring is bad - - re wiring and connector connection;

2. Check whether the power supply voltage is in the range of working range) to the normal position range;

3, ring) - whether desoldering re welding;

4, coil short circuit) replace coil;

5, the work pressure difference is not appropriate - adjust the pressure difference) or replace the matching solenoid valve;

6, fluid temperature is too high) replace the appropriate solenoid valve;

7, impurities to the solenoid valve main spool and moving iron core stuck - cleaning, if there is a seal damage, should replace the seal and install the filter;

8, liquid viscosity is too large, the frequency is too high and life has been -) replace products.

(two) solenoid valve can not be closed:

1. The seal of the main valve or the iron core has been damaged) replace the seal;

2, whether the fluid temperature, viscosity is too high) replace the counterpart solenoid valve;

3, impurities into the solenoid valve core or moving iron core) for cleaning;

4, the spring life has arrived or deformation) replace the spring;

5, orifice balance hole plug -) timely cleaning;

6, the work frequency is too high or the life has arrived -) re-election products or replacement products.

(three) other circumstances:

1, internal leakage - check whether the seal is damaged, spring assembly is not good;

2, leakage leakage - loose at the junction or seal is broken - tighten screws or replace seals;

3, there is noise when power is on -) the fastener is loosened and tightened. Voltage fluctuation is not allowed and voltage is adjusted. Impurities or irregularities in the core pulling surface, timely cleaning or replacement.
