3/8″ Inch Stainless Electric Water Solenoid Valve Normally Closed

 

WIC Valve 2SCW Series 2-way normally closed general purpose process electric solenoid valve is to control On/Off of air, inert gas, liquid, and vacuum. This electric solenoid valve has one 3/8″ inch NPT inlet and one 3/8″ inch NPT outlet port. Valve stays close when the coil is de-energized, and it opens when energized.  2SCW Series solenoid valve comes with a ED 100% encapsulated coil which suitable to operate in continuous service and constantly energized.2SCW Series solenoid valve is a zero differential valve which can be operated at 0 PSI (Vacuum) and it can be mounted in any position.

How to connect DIN 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 Cv ?

Cv = Flow coefficient or flow capacity rating of valve. The flow coefficient C_v is the volume (in US gallons) of water at 60°F that will flow per minute through a valve with a pressure drop of 1 psi across the valve.

Mathematically the flow coefficient can be expressed as:

where:
C_v = Flow coefficient or flow capacity rating of valve.
F = Rate of flow (US gallons per minute).
SG = Specific gravity of fluid (Water = 1).
ΔP = Pressure drop across valve (psi).

 

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 DIN connector for this 2SCW series valve is a DIN 43650A 18mm (PG11) type. 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 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.
