Basically a side entry valve would be in two or three parts, and a top entry valve is a compelete housing, the top entry valve would be used where access is difficult to remove and work on the valve, you can work on a top entry while it is on line where as the side entry valve would have to be removed
A two way valve is also known as a shut off valve with two ports. A basic two way valve acts like a stock flow valve and allows water to come in and go out.
Generally there's a spring holding the valve close, when the internal pressure is great enough, the valve opens - until the pressure drops. In some applications, there's a weight holding the valve closed.
Moduflex dual valve combines two, 4-way valves into one valve body, it features two independently operated valves in the Size 1 valve body. :)
Answer On "older" aircraft, the pilot applies brakes that moves cranks and pulleys that opens the Brake Valve. The Brake Valve ports regulated pressure to the Anti-Skid Manifolds. The Manifolds provides the pressure to the brakes. If the Anti-Skid computer detects a skid condition, the computer commands a pair of matching brakes to release pressure to allow the wheels to spin back up. The anti-skid releases brakes in pairs to keep an equal braking applied to each side of the aircraft. If the braking is unsymmitrical, this could cause the a/c to go into a spin.
The anti syphon valve works by only allowing water to flow in one direction. For irrigation purposes, it prevents water from the system from being siphoned back into the water supply line.
An anti-siphon (or, anti-syphon) valve is a device that prevents liquid from returning to the line from which it came if a siphon action occurs. An anti-siphon device is frequently required on outdoor irrigation systems to prevent possibly contaminated water to be drawn back into the water supply lines if water pressure decreases in the water supply line. An anti-siphon device is not the same as a check valve. A check valve allows flow in only one direction, and requires pressure to function. An anti-siphon valve opens to the atmosphere when there is reduced or no pressure in the line.

It's all in the name. Anti-syphon valves prevents syphoning (when contents of a syringe, by the force of gravity, empties into a vein for example). Anti-reflux prevents back flow of one infusion line into an other infusion line (only needed if several infusions are going down the same cannula).
With the ones I've seen, they simply screw on to the bib just like a hose would. So you just unscrew the old one and screw on the new one. In Texas with homes built in the 1980's forward, you usually cannot remove just the anti syphon device because the commercial plumbers remove or break off the set screw that comes with the assembly that would allow for removal. I had to have a plumber remove the hose bib (simple process) and then replace it along with a new anti syphon valve. This put an end to the annoying dribbling of water. Cost me $65. I'll do it myself the next time as it is actually quite simple now that I know how to do it. I will install it with a syphon valve that I can remove.
Yes.
Valve Anti-Cheat was created in 2002.
You can not. There is an anti-siphon valve in the filler neck.You can not. There is an anti-siphon valve in the filler neck.
A syphon is used in 3 ways, either when draining a geyser, (particularly a gravity feed geyser), when installing a geyser, an anti syphon loop has to be installed to prevent the geyser from draining when the water has been switched off and lasted a syphon method can be used in the older type of toilet flushing mechanisms.
Syphon Filter happened in 1999.
It is normally spelled Siphon, but Syphon is an alternate spelling for the same word.
