learn about ball valve

the ball valve
what is ball valve??
Ball valve is one type of quarter turn valve, is quite literally a ball placed in a passageway through which fluid flows. The ball is controlled from outside the valve, often with a handle that is turned 90 degrees, or a quarter turn, back and forth to open and close the valve.A ball valve can also be a three-way valve if a third hole is bored partially through the ball, until it meets the main hole, forming a T.
ball valves are the three different types of rotary valves used in industrial plants. They are widely used in fluid-handling systems for flow control. These types of rotary valves are suitable for corrosive applications. They are used in detergent, pharmaceutical, chemical, rubber, pulp and paper plants, water treatment systems, textile mills and food processing plants, In general, ball valves offer many advantages when contrasted with other valve types. They provide superior ease of operation and can maintain and regulate high volume, high pressure and high temperature flow. Most ball valves offer rugged construction providing for a long service life, and a comparably low cost. Additionally, the design of the regulating element allows the valve to function without the complications of side loads, typical of butterfly or globe valves, and the valve design permits inspection and repair of seats and seals without removing the valves’ body from the line.

Do u know how a Slide-Check Valve Works

In fact, I am just new here, and i don't know more about valve. however i can see them everywhere in our daily life. Today i saw a website that introduct Slkde-check valve works. I feel interest in it, so i want to share to all of you.
When the slide is forward, the entire line, from the tank to the marker valve chamber is pressurized (see Fig. 1.) The blue color depicts the high-pressure gas. In the Forward Position, the marker is ready to fire.
When the slide is back, there is no pressure in the line between the marker and the slide-check. In the Back Position, the marker can be removed from the remote, without de-pressurizing the entire line or having to turn off the tank (see Fig. 2.) The line between the tank and the slide-check remains at tank pressure as depicted by the blue color.
