1/4″ Inch Fast Response Direct Acting Electric Solenoid Valve

 

2BCK Series 2-way normally closed electric solenoid process valve is to control On/Off of air, inert gas, liquid, and water. This industrial fast response electric solenoid valve has one 1/4″ inch NPT inlet and one 1/4″ 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.  2BCK Series solenoid valve comes with a ED 100% encapsulated coil which suitable to operate in continuous service and constantly energized.  This compact electric process solenoid valve features with 2 of the M5 size convenient mounting holes for easy installation, valve can be mounted in any position.

Solenoid Valve Frequently Asked Questions:

How to connect DIN 43650A connector with wire?

To connect the wire to DIN connector is simple and easy, shown below is the 4 easy steps:

1. Remove the Philip screw from the 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. On the back of the terminal block, it makes 1, 2 and Ground.

For the DC DIN coil, connect 1 to positive, and 2 to negative. For the AC DIN coil, connect 1 to Hot wire, 2 to Neutral wire, and Ground to Ground wire if required.

What is ED 100% Coil Duty?

ED 100% indicates suitability of the coil to operate in “continuous service”, in other words it is good for constantly energized.

 

What is IP65?

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

IP Second number – Protection against liquids
