the disadvantages are that over a period of time gate valves seize and become in operable. also the handles of gate valves corrode quickly and gate valves don't entirely close properly making it difficult to solder. Gate valves are used for positive shut off and Gate valves are not designed for throttling like a globe pattern type . Gate valve fail because the installer has no idea what these types of valves are intended to do such as main steam shut off's or water mains..If properly used and installed correctly these valves last over 100 years under extream conditions
What else can I help you with?
What is the disadvantage and advantage of photo diode and transistor?
photo diode donot work for long distance photo diode act as a receiver
What is the direction of current flow in a diode valve?
Inside the diode valve the conventional curret flow is from anode to cathode. The electron flow is from cathode to anode.
What kind of device is diode?
It is an electronic device. A sort of one way valve for electricity.
What causes a diode to fail on a 240v solenoid valve?
Why would it? And is this the diode across the windings of the coil that supplies the back EMF (inductive kick) supression? There isn't a good reason for it to fail. A bit more information is needed here.
What property of a diode enables it to convert ac to dc?
A diode allows electrons to pass only in one direction. During the negative half cycle of an alternating current the diode will not allow electron current to pass. It is like a one way valve. This property of diode enables it to convert AC into pulsated DC
What is diode volve?
I think you mean 'diode valve'! A 'valve' is the British term for what Americans call 'tubes' or, more accurately, 'vacuum tubes'. So, a 'diode valve' is a thermionic valve generally used as a rectifier, much in the same way that a semiconducting diode is used, these days.
What is the disadvantage of gunn diode?
Gunn Diodes are used in high frequency electronics. The advantages are increased efficiency and improved temperature stability while a disadvantage is the Gunn Diode can get burned out.

What is an equivalent diode of a triode valve?
Hard to answer this one.The triode is a diode with a control electrode (the grid) added.The only useful answer is that a triode is a voltage-controlled doide.Try asking the question so that it can be answered more usefully.
What is the purpose is of a diode?
The purpose of a diode is to allow electric current to pass in one direction while blocking electric current in the opposite direction. It is for this reason that diode is usually referred as the check valve.
How does a diode work on an engine shutoff solenoid?
A diode is a one way check valve basically. it will let current pass one way but not the other.
What kind of device is diode?
It is an electronic device. A sort of one way valve for electricity.
What is a power diode?
A Power Diode is used when a large current is involved which needs a larger junction to dissipate the heat generated. An advantage of using the Power Diode is it is able to withstand high voltage without being damaged. A disadvantage about the Power Diode is that being a large junction it is unable to stand high frequency applications.
What are the early developments in electronics?
The earliest electronic device was the diode which was invented in 1873. The first diodes were both crystal and thermionic valve (vacuum tube) based devices; the first valve diode was in 1873, the first crystal diode in 1874. Edison also developed a diode independently. In the early 20th century, the first triodes were developed - which could amplify signals and electronics was largely valve based until the early 1960s, despite transistors being developed in 1923.
Disadvantage of using diode as shunt element in clipper circuit?
In shunt clippers, when the diode is in off condition, transmission of input signal must take place to output. But in the case of high frequency input signals, diode capacitance affects the operation of circuit adversely and the signal gets attenuated (which means that, it passes through diode capacitance to ground).
