as a professional manufacturer of valves, valve information today early abstract:

about the people in the use of electric valve, met a few problems and small fault reason reconciliation method!

a, electric valve cannot be closed

the main Industrial Valves core and the iron core of seal damaged & rarr; Replace the seal

fluid temperature, viscosity is too high & rarr; Replacement of the electric valve

there are impurities into the electric valve valve core production or moving iron core & rarr; Cleaning

spring had come to life or deformation & rarr; Replace

orifice balance hole plug & rarr; Timely cleaning

work frequency is too high or life has come & rarr; Re-election or update products

2, electric valve does not work after the power supply

check whether the power connection bad & rarr; Connectors and wiring connection again

check whether the power supply voltage in & plusmn; The scope of work - → Adjusted to normal position range

if coil desoldering & rarr; Welding again

coil short-circuit & rarr; Replace the coil

work differential pressure is not appropriate & rarr; Adjust the pressure difference & rarr; Or replacement of proportion of electric valve

fluid temperature is too high & rarr; Change the proportion of electric valve

have impurities to make electric valve of main valve core and the moving core card die & rarr; Cleaning, such as the seal is damaged to replace seal and install filters

liquid viscosity is too large, the frequency is too high, and had come to life & rarr; Replacement products

three, other

internal leakage & rarr; Check whether the seal is damaged, the spring is bad assembly

external leakage & rarr; Joint looseness or seal has bad & rarr; Screw or replace seal

electricity from time to tome noise & rarr; The strong leader a loose and tighten. Voltage fluctuation is not allowed within the scope of adjust voltage. Core surface impurities or uneven absorption, clean or replace in a timely manner. as a domestic high-end valve manufacturer, always respond to national policy and called for, committed to researching, developing and manufacturing electric butterfly Industrial Valves, stainless steel ball valve, discharge valve, electric gate valves, stainless steel gate, stainless steel Industrial Valves, stainless steel check valve, high pressure gate valves high-quality let customer trust of good valve, the valve to keep traditional valve product sales profits to escort for the innovation research.
