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.
What is the difference between a Hot water shut off valve and cold water shut off valve?
the hot water valve shut off valve shuts off the hot water. The cold water valve shuts off the cold water. ;()
Difference between butterfly valve and gate valve?
Butterfly valve refers to a kind of valve whose closing part (butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. It mainly plays a role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. The butterfly valve is usually 90° from fully open to fully closed. The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. The opening and closing part of the gate valve is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The advantages of the gate valve: small fluid resistance, less effort to open and close, no restriction on the flow of the medium, no turbulence, no pressure reduction
How do you change a angle valve?
By shutting off the water supply prior to this valve of course
How and where would you install a shut-off valve on a wall-mount faucet?
I take it that you are mounting it out side, put the shut off valve in side, with a drain on it,
Why wont supply valve for toilet shut off after valve is closed?
It needs a new washer in it.
What is the valve called that shuts off the supply line?
The shut off valve.
What is meant by air to open valve?
An air to open valve is a type of control valve that requires air pressure to be applied in order to open the valve. When the air pressure is removed, the valve will close automatically. This design is commonly used for safety-critical applications where a fail-safe operation is needed.
What does a motorcycle air cut off valve do?
AIR CUT OFF VALVES PREVENT "AFTER BURN" GENERATED WHEN THE THROTTLE IS SUDDENLY CLOSED WHEN THE THROTTLE IS SUDDENLY CLOSED, THE VALVE TEMPORARILY CLOSES THE SLOW-JET PASSAGEWAY---CREATING AN INSTANTLY RICHER MIXTURE AND THUS REDUCES "POP" SOUNDS UPON DE-ACCELERATION
Why is it called a butterfly valve?
Because the inner area where the fluid moves has a gate which is shaped like a butterfliys wings. Passing through the centre of this gate is a rod which ends outside the valve where the handle is attached. When the gate is open it allows flow, when closed the gate seals off the valve stopping flow or if require can be partially turned to restrict flow
What is a gas butterfly valve?
A butterfly valve is from a family of valves called quarter turn valves. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is open, the disc is rotated a quarter turn so that it allows unrestricted passage. The position of the disc is effected from outside the valve. gas butterfly valve is one kind of butterfly valve, the main feature is that all the functions are supported by gas just as the Electric Butterfly Valve which supported by electric.

What would make a hot water tank blow out at the seam?
The temperature-pressure relief valve has been removed, blocked off or is stuck closed.

It's called the EGR tube.
