110v ac solenoid energize time

[engineer1000]

Another solenoid question, If I have 110Vac solenoid value can I power it from 115Vac transformer and can I keep it energized for a reasonable amount of time say a few hours or will it get too hot and the coil burn out

See rated voltage range specificated at device label.

Solenoids are rated for an inrush current for when the core is out, I would think that the designer reckoned that the core would "clunk" in in a matter of a few 100 milliseconds. Then the magnetic path is completed and the current will fall dramatically to say 15% of the core out current. So I would say that a 5% voltage overload with the core IN is OK, but 100% operating voltage with the core out is not OK.

A typical solenoid requires 10% of the normal current to remain energized. To accomplish this, use one of the following:

Mechanical hold in resistor
Capacitor discharge and hold in resistor
Transistorized hold in circuit
Pulse-width modulation
Pick and Hold
Dual voltage
Multiple coils

also choose Attribute
Quiet
Long Life
Miniature
Battery Operated
High Speed

Acceptable voltage ratings are usually +/- 10% of nominal. So 115Vac on a 110Vac solenoid is just fine.

Having said this.....
There are continuous duty and intermittent duty solenoids.

Given the same solenoid size, an intermittent duty has significantly greater pulling power than a continuous duty. But it will burn out if not allowed to rest and cool off.

Which type do you have?
