US-8 G1/4'' 2/2 NC UNI-D Type Electromagnetic Valve
The below is US-8 / UD-8/ 2W025-08 G1/4'' Port Size 2/2 Way Normally Closed (NC) UNI-D Type Electromagnetic Valve.
Featues and benefits:
1. Direct-acting normally closed type two-position two-way Solenoid Valve, quick and sensitive to change;
2. Compact structure, small size, light weight, convenient assembly and disassembly;
3. Body material brass, electromagnetic coil heat resistance grade is B grade, standard seal material defaults to nitrile rubber, suitable for a variety of working media (can be better fluoride rubber seals according to needs);
4. The protection level of the coil is IP65, and the power connection mode is lead-out type and junction box type. (Generally, the default is lead type, if you need to connect with the sales staff);
5. DC12V and DC24V should be equipped with a power supply of 2A or more current to start the normal operation of the valve;
6. The pipe water of the solenoid valve outlet cannot be recirculated, and a check valve is required if it will return.

Different solenoid coil of G1/4'' 2/2 NC UNI-D Type Solenoid Valve for you to choose:
Solenoid valve failure and elimination:
(1) The solenoid valve does not work after being energized:
1. Check if the power supply wiring is bad → re-wiring and connector connection;
2. Check if the power supply voltage is within the ± working range → adjust to the normal position range;
3. Whether the ring is desoldered or re-welded;
4. Short circuit of coil → replace coil;
5. Is the working pressure difference inappropriate? Adjust the pressure difference → or replace the proportional solenoid valve;
6. The fluid temperature is too high → replace the proportional solenoid valve;
7. There are impurities to make the main valve core and moving iron core of the solenoid valve be stuck → clean. If there is damage to the seal, replace the seal and install the filter;
8. The viscosity of the liquid is too large, the frequency is too high and the life has reached → replace the product.
(2) The solenoid valve cannot be closed:
1. The seal of the main valve core or the iron core has been damaged → replace the seal;
2. Whether the fluid temperature and viscosity are too high → replace the solenoid valve of the opposite port;
3. There are impurities entering the solenoid valve spool or moving iron core → cleaning;
4. The spring life has reached or deformed → replace the spring;
5. The orifice balance hole is blocked → timely cleaning;
6. The working frequency is too high or the life is up to → re-elect the product or replace the product.
(3) Other circumstances:
1. Internal leakage → check if the seal is damaged and the spring is not properly assembled;
2. External leakage → loose connection or seal is broken → tighten the screw or replace the seal;
3. There is noise when energized → the fasteners on the coil are loose and tightened. The voltage fluctuation is not within the allowable range and the voltage is adjusted. The iron core suction surface has impurities or unevenness, and is cleaned or replaced in time.
