There are a few different designs:
Parallel disk gate valves use two disks with a spring in between them, sliding into the seats. At low pressure, the spring forces the disks outward against the seats, sealing off the valve. At high pressure, all the sealing is accomplished by the downstream disk.
Wedge gate valves use a tapered disk that slides into two seats set at a slight, converging angle. The wedging action provides the sealing force between the disk and the seat.
Single disk gate valves are used where the flow is always one way (like sluices on dams). There is some flexibility in the attachment of the disk to the stem, so the differential pressure on the disk pushes it against the seat, sealing it off.

What the common types of atelectasis?
Resorption atelectasis
What controls the opening and closing of the clam valves?
The adductor muscles control the opening and closing of the clam valves. When these muscles contract, the valves close, and when they relax, the valves open. Clams use this mechanism to protect themselves from predators and regulate their internal environment.
What 12 veins do pigs and humans have in common?

How many valves are in a sheep's heart?
There are 2 valves in a sheep's heart. They are the mitral and tricuspid valve. The sheep also has a 4 chamber heart that is very similar to a human heart.
What are the different types of MTB valve types available for mountain bikes?
There are primarily two types of valve types available for mountain bikes: Presta valves and Schrader valves. Presta valves are typically found on higher-end bikes and are thinner with a lock nut to secure them. Schrader valves are more common and are similar to car tire valves, with a spring-loaded mechanism.
What are the different valves available for bike tires?
There are three main types of valves used for bike tires: Schrader valves, Presta valves, and Woods valves. Schrader valves are the most common and are similar to those found on car tires. Presta valves are thinner and require a separate pump attachment. Woods valves are less common and are often found on older bikes.
What are the different types of bike tire valves available for use?
There are three main types of bike tire valves: Schrader valves, Presta valves, and Woods valves. Schrader valves are commonly found on most bikes and are similar to car tire valves. Presta valves are thinner and longer, often used on higher-end bikes. Woods valves are less common and are typically found on older or vintage bikes.
What are the different types of bicycle tire stem types available in the market?
The main types of bicycle tire stem types available in the market are Presta and Schrader valves. Presta valves are thinner and commonly found on road bikes, while Schrader valves are wider and more common on mountain bikes and children's bikes.

What are the different types of bike tire valve stems available in the market?
The main types of bike tire valve stems are Schrader valves and Presta valves. Schrader valves are wider and more common, while Presta valves are thinner and often found on higher-end bikes. There are also tubeless valves for tubeless tires, and some specialty valves for specific purposes.
What are the two types of bicycle tire valves and how do they differ from each other?
There are two types of bicycle tire valves: Schrader and Presta. Schrader valves are wider and more common, found on most bikes and cars. Presta valves are narrower and often used on high-performance bikes. Presta valves require a separate adapter for inflation, while Schrader valves can be inflated with a standard pump.
