JOIL Type JICI JISI JIFI JIHI Series Pulse Jet Solenoid Valve Coil
Ths is a solenoid coil mounted on JOIL JICI JISI JIFI JIHI series diaphragm pulse valves, which is a coil of wire which wraps around a piston type of device. When a solenoid is energized, a magnetic field is created when current is applied and the piston (plunger) of the mechanism lifts off the port in the valve assembly- which results in the valve opening. When the power is shut off to the solenoid the electromagnetic field dissipates and the plunger assembly seats back down over the port and the valve shuts down.
The effective current should be measured in AC regime, and that current should be set as a target for DC regime as well. Some ways to achieve that target would be reducing the supply voltage or using a current-limiting resistor.
Using a coil rated for DC current with an AC power supply, imposes the risk of vibrations since DC solenoid valves might not contain a shading ring or a rectifier circuit. These vibrations might damage the solenoid by stressing the components over time, and they can contribute to noise levels in the room. This can be worked around by using an external full-wave rectifier circuit with a capacitive filter.
Another problem is that the effective current will be several times lower in this case, and the magnetic force generated by the coil might not be large enough to move the armature from its resting position. A solution would be to use a larger voltage so that the effective current matches the rated current of the solenoid.

Insulation & Heat Dissipation:
1. Class F is encapsulated Nylon coil. Class H is encapsulated Phenolic coil (types H1 and H2 are open wound (not encapsulated)).
2. Consider the environment (see IP ratings). If the environment is higher than the IP rating of the coil takes measures to protect (ie shelter from the rain or heavy hosing).
3. Note that the coil must still be able to vent the excess heat (do not lag or place coil in a sealed housing without ventilation. This will cause the coil to heat stress and fail).
4. Coils can tolerate higher than rated ambient temperatures when energized for short periods of time. This time varies depending on the coil wattage, ambient and media temperatures.
5. Use the Power Saving plug to reduce the operating heat in process coils (only available in 240v Ac and 24v DC) that are energised for long periods of time in high ambient temperature applications.
6. Other considerations are Power, Media temperature and AC ripple in DC power supplies (they should be regulated and smoothed DC supply). Also the valve elastomer selected for specific chemical and media applications must be taken into consideration if operating in a high ambient environment.
7. Another consideration type H1 and H2 coils are open wound (IP54) and have the ability to dissipate heat quicker than the encapsulated coils (IP65) even though they are all Class H rated. Their lower IP rating must be taken into account.
8. Coils used in Process Systems valves are designed and tested for continuous service 100% duty cycle (ED100%).
9. They all meet the IEC 216 thermal endurance specifications when factory tested. Specific field applications are outside of our control and the site engineer must test to suit the environment.
