Is the water line open or closed when the ball valve handle is in line with the pipe?
When the handle is in line with the pipe, the valve is open.
What does a water inlet valve on Ice maker do?
Opens and closes an internal valve to provide/cut-off water to the icemaker - responds to pressure signal from the ice-maker to deliver/cutoff water - ice-maker signal activates an electric solenoid that open/closes the valve for water flow.
Ice maker Refrigerator Repair?
Most refrigerators in use today have ice makers that may stop working from time to time. The refrigerator’s ice maker receives its water supply from a water valve. The water valve is the first component of the refrigerator that should be checked when there is a malfunction with the ice maker. To operate, the ice maker closes an electric circuit enabling the water valve to open. Water will then flow through the water valve into the ice maker. The ice maker will then begin the process of making ice cubes and placing them in the ice tray. The water valve has a filter that keeps out particles from entering into the ice maker through the water supply. These particles can sometimes build up at the water valve filter and may even block the flow of water to the ice maker. When the flow of water in the water valve is restricted due to build up, it can cause the still water freeze in the valve. One solution is to heat the water valve with a hair dryer to melt the ice buildup in the ice maker. Be careful not to heat the plastic of the refrigerator too much causing it to melt. These particles can also lock the valve in the open position filling up the ice maker to excess. Sometimes an open solenoid coil winding can cause the valve to remain closed. This will not allow the water to flow to the ice maker as the plunger remains closed. In order to do further tests on the refrigerator to determine the fault with the ice maker is to test the current flow. This will not only be a safer measure for you as you attempt to repair your ice maker, but will also ensure the various components are operating as they should. Your diagnosis will most likely be related to the water valve, but if your refrigerator is old it could mean your ice maker needs to be replaced. Occasionally the electrical connections can sometimes get short circuited or disconnected during use. Thoroughly examine all the parts of your refrigerator with the proper tools and testing equipment.
Can the water tank of a toliet overflow?
Sure if the valve gets stuck open and the flapper get stuck closed.
How do you know the gas valve is open or closed?

Is normally open valve and fail open valve the same?
"Normally Open" or "Normally Closed" are classifications that refer to actuated (not manually operated) valves. For an actuated valve, the "normal" state refers to its position when the actuator is not energized.Therefore a normally open valve is one that is open until the actuator is energized to close it; if power to the actuator fails, the valve opens or "fails open".Likewise with a normally closed valve if power to the actuator fails, the valve closes or "fails closed".The "normal" state of an actuated valve must not be confused with the "usual" position of the valve during routine operation of the system. A normally closed valve may be open continuously over a long period of time while a process is running, but it is still a normally closed valve. It just happens that this normally closed valve is usually open.For an actuated valve to return to its "normal" position, there must be some force, often a spring, that moves the valve from its actuated state back to its normal state. If a valve is actuated to open and then actuated to close, it will "fail" in whichever position it is in when the activator is de-energized. This type of a valve is not considered "fail safe".A normally closed valve might be used in an application such as the loading of gasoline transport trucks where in the event of a power or automation system failure, you would want to stop flow.A normally open valve might be used in a situation where you want flow to continue in the event of a power or automation system failure. This might be the case for the cooling water system for a nuclear reactor or for an actuated valve on the water piping to the fire protection system.
What is the difference between a fail open valve and a fail closed valve?
Lets liken this to a garden hose, a hose in the normally open position has water flowing through it until it is closed by turning the spigot off, normally closed is the reverse. Oddly enough when it comes to an electronic relay the opposite is true, whereas the switch is in the open (normally open) position therefore having no current passing through it until a switch to close the circuit and allow current to flow. Normally closed has current flowing at all times until the switch interrupts it stopping the flow of electricity.
How can you tell if a ball valve is opened or closed?
The position of the handle indicates the direction of the opening through the ball, IE. handle in line with pipe, valve is open, tangent to pipe, valve is closed.
When your pump is on it sends water out the drain in your back yardno matter if you have the main drain valve closed or open How do you fix this problem?
Is this a sand filter? How many valves control the flow of water? It appears the b/w valve is defective.
What AV and semilunar valve positions during ventricular diastole?
The AV valve is open and the semilunar valve is closed during ventricular diastole.
What is a AARL strip circuit?
does the bypass valve on elution heater be open or closed
What is the difference between a control valve and a gate valve in a stand pipe system?
a gate valve is a one way totally open or closed valve, a control valve is a variable valve.
