1, sekim sapos pawa waya i stap long:
Check the connectors and its wiring connection is powered on with the supply voltage, the adjusted to normal position range whether desoldering, coil to coil short circuit welding, replacement coil work differential pressure is not appropriate, the differential pressure, fluid temperature is too high, or replace solenoid valve commensurate change of proportion of solenoid valves have impurities to make electromagnetic valve of the main valve core and the moving core kad i dai pinis, Karim aut klinim. Sapos sil i bagarap, senisim sil na putim filta.
2, solenoid valv i no inap pas taim yu stap long wok:
Sakim seel sapos main valve core o moving iron core i bagarap, whether temperature bilong fluid na viscosity i mipla i likim, na sapos yu mas putim bek solenoid valve, ol valve core i kamap long ol impurities we i stap long solenoid valve o moving iron core, klina, spring i bin go long o deform, laif i mas kisim bek, orifice balance hole i blok, mas klina taim, working frequency i tupela high o gat laif.
