1/8" Electric Fast Response Solenoid Process Valve DIN Connector with LED Indicator Normally Closed


WIC Valve 2ACK Series 2-way normally closed electric solenoid valve is to control On/Off of air and inert gas. This direct acting electric solenoid valve has one 1/8" inch NPT inlet and one 1/8" inch NPT outlet port. Valve stays close when the coil is de-energized, and it opens when energized. Valve has two holes in the bottom and can be mounted in any position.  2ACK Seris electric solenoid valve comes with a ED 100% coil which suitable to operate in continuous service or in other words constantly energised.  This valve is a Zero differential solenoid valve which can be operated at 0 PSI (Vacuum), no minimum pressure is required.

How to Rotate DIN Plastic Connector?


Shown below is the 4 easy steps to rotate the DIN plastic housing:


1. Remove the Philip screw from the DIN plastic housing protector.


2. Unplug the plastic housing from the DIN coil.

3. Remove the terminal block from the plastic housing.  Use the Philip screw to push the terminal block out from the plastic housing.

4. Rotate the DIN plastic housing to 180 degree, then plug into the terminal block and put the Philip screw back.

5. Finish DIN plastic housing rotation.




What is the advantages to use DIN Connector?

Instead of using the Grommet lead wires, the coil has the prongs or pins to connect a standard DIN connector. Therefore, the coil will have a male connection and the plug connecting to the coil is a female connector.  The advantages of the DIN Connector is that it allows a quick valve or coil exchange. Yet it is a excellent insulation properties and good for water tightness.


What is IP65 Protection Class Mean?

Ingress Protection (IP) ratings are developed by the European Committee for Electro Technical Standardization (CENELEC) (NEMA IEC 60529 Degrees of Protection Provided by Enclosures - IP Code), specifying the environmental protection the enclosure provides.

The IP rating normally has two (or three) numbers:

1) Protection from solid objects or materials

2) Protection from liquids (water)

3) Protection against mechanical impacts (commonly omitted, the third number is not a part of IEC 60529)

IP First number - Protection against solid objects

0 No special protection
1 Protected against solid objects over 50 mm, e.g. accidental touch by persons hands.
2 Protected against solid objects over 12 mm, e.g. persons fingers.
3 Protected against solid objects over 2.5 mm (tools and wires).
4 Protected against solid objects over 1 mm (tools, wires, and small wires).
5 Protected against dust limited ingress (no harmful deposit).
6 Totally protected against dust.


IP Second number - Protection against liquids

0 No protection.
1 Protection against vertically falling drops of water e.g. condensation.
2 Protection against direct sprays of water up to 15o from the vertical.
3 Protected against direct sprays of water up to 60o from the vertical.
4 Protection against water sprayed from all directions - limited ingress permitted.
5 Protected against low pressure jets of water from all directions - limited ingress.
6 Protected against temporary flooding of water, e.g. for use on ship decks - limited ingress permitted.
7 Protected against the effect of immersion between 15 cm and 1 m.
8 Protects against long periods of immersion under pressure.
