What does a solenoid do on a valve?
A solenoid valve is a type of valve that uses an electrical current to actuate or shift a spool or cartridge consisting of a solenoid coil and tube assembly. Basically, this valve type uses an electric current to shift a pin to perform simple A/B tasks such as open/close valve spools. The designation "solenoid" means that the valve operation is electrical not manual. Maybe the easiest way to describe a solenoid valve is by thinking about an automatic car lock. The electric current get triggered, the pin gets pushed up and the doors are unlocked. A reverse current gets triggered, the pin gets pushed down, and the doors are locked.
In a solenoid valve system if the voltage on the coil is 118 VAC and a continuity test of the solenoid and coil measures 80 ohms yet the solenoid will not allow water flow the most likely cause of?
There could be more than one reasons. Applied voltage may not be 118 volts. Solenoid valve may have been stuck mechanically. Solenoid coil could be faulty, partially short.
Why two solenoid valves are required for on-off valve?
Some times on/off valves are to large to be actuated using one solenoid valve,but most of the on/off valves are being actuated using only one solenoid valve
How does a contactor energise?
Contactors have movable contacts in them which are operated by the action of the solenoid that they are attached too. This solenoid is basically an electromagnet with a spring that resets the contacts to the open position when current is removed from the solenoid's coil/windings. When an electrical current is fed through the coil of the solenoid it creates a magnetic field; the force of the field is stronger than the opposing force of the restting spring thus the moving part of the solenoid which has the contacts attached to it, moves down completing the electrical circuit. Contactors are usually used in cases where the voltages and currents levels to be used are way beyond the capacity of a normal switch. A common example would be as a direct on line starter for a large electrical motor, which usually have large starting current of up to 5-8 times the run current of the motor. It is also important to note that voltage used to energize the contactors coil can be much smaller than the actual voltage be conveyed by the contacts which feed the electrical load.
What takes place when the energizing of a chime circuit as the push button is pushed?
Electrical current in solenoid creates a magnetic field.Magnetic field in solenoid pulls in armature.Armature causes striking mechanism to produce first chime of bell.Interruption of electrical current in solenoid causes magnetic field to collapse.Spring pulls armature out of solenoid.Armature causes striking mechanism to produce second chime of bell.Electronic doorbell chimes work differently, offering more options.
Cant open rear door of Vauxhall Vectra as solenoid is broken. How do I open it and replace solenoid?
They can be pried open from inside the boot, a little patience and a strong screwdriver.
What will be the reactions if a solenoid is fed alternating current?
The solenoid with repeatedly close and open. Perhaps more rapidly than designed and then overheat and become damaged.
What is a VTEC sensor?
its not really called a vtec sensor. its a Vtec Solenoid, the solenoid has an oil pressure switch mounted on the solenoid. When the head reaches a certain pressure the oil pressure switch sends a signal to the ecu and the ecu sends a signal to the solenoid to open the extra valves
What is meaning of computer code po403?
It means something is not right with the car's EGR valve.These are possible causes, starting with the most common.Bad EGR solenoidExcessive resistance in control circuit (PCM controlled ground) due to an open, chafing or damage to the harnessPoor connection at the EGR solenoid harness (worn or loose pins)Water intrusion at the EGR solenoid harnessBlockage in EGR control solenoid holding solenoid open or closed causing excessive resistanceLoss of supply voltage to EGR solenoid
What is solenoid?
A solenoid is a long cylindrical coil of wire consisting of a large number of turns bound together very tightly. A solenoid is usually used to produce a magnetic field to pull the armature of a relay, causing electrical contacts in the relay to open and/or close switching current flow.
How many volts does the P7100 fuel shut off valve use to hold open?
12 volts to hold open the shut-down solenoid
Your car wont start you here a clicking noise coming from somewhere near the glove box could it be your starter solenoid?
It may be the starter solenoid that is clicking. If the battery is very low when you try to start the car, the solenoid will engage but the starter will not turn. Because the battery is so low, there is not enough power to hold the solenoid closed (in the start position) and try to turn the started so as the starter draws power, the solenoid clicks open, The starter doesn't draw any power with the solenoid open so the solenoid has power to close again, the starter tries to draw power and the cycle repeats. The sound seems to come from behind the glovebox because the solenoid is probably mounted on the passenger side of the engine compartment.
Murray mower will crack if you cross it out at solenoid. Wont crank with switch. Any suggestions on this problem. I am thinking bad solenoid or one of the safety switches. How can you check them?
ck at the solenoid white wire should read 12 volts.If not one of the safety switches are open.

How do you find vacuum leak in 2001 jeep TJ Sport?
Faulty torque converter clutch solenoid valve Torque converter clutch solenoid valve harness is open or shorted Torque converter clutch solenoid valve circuit poor electrical connection Low transmission fluid level Dirty transmission fluid Could be a problem with the harness to the Torque Converter Clutch (TCC) solenoid, the TCC solenoid connector or the TCC solenoid it self.
What is a solenoid on a paintball gun?
The solenoid can refer to two things: The solenoid on electrically assisted sear tripper markers (like a Tippmann with electric trigger) the solenoid is an electro magnet that moves a long pole that trips the sear that fires the gun. A solenoid valve is an electronically controlled valve (like on a Smart parts ion, or any gun you don't have to cock) it uses electric current to open and close.
How do you fix a P0449 evaporative emission control system vent valve solenoid circuit malfunction on a 2006 Chevy silverado?
Usually the problem with this code is an open vent solenoid valve. 12 volts is provided to solenoid and the pcm grounds the solenoid. When the pcm checks the circuit it is looking for 12 volts on the wire at pcm. The pink wire should have 12 volts and the white wire should be the ground circuit from the pcm. Ohm your vent valve it will probably be open.
