Wafer Check Valve, or non-return valves, allow water or other material to flow in only one direction, and stop the material from flowing in the opposite direction. They are installed in pipe lines and do not require any activation from outside. Instead, they sense when the material in the pipes is beginning to move [...]
Swing Check Valve prevent the reversal of flow in plumbing systems. These valves achieve control over the direction of flow through the use of a control element. This element can take the form of a disc-shaped flapper, plunger or free-floating ball, depending on the type of valve. Most check valves are purely mechanical, but [...]
Dual Check Valve prevent the back flow of liquid or gas. Sprinkler and irrigation pumps often use check valves to stop water from draining out of the pump body when not in use. If the water flows out, the pump may require priming before it will siphon water again. Check valves are also used [...]
Inside the valve, there is a ball that has a port, which is actually a hole at the middle. When this hole is aligned with both Trunnion Mounted Ball Valve ends, liquid can flow easily through it. After the valve has been closed, the hole becomes perpendicular to the valve ends impeding the flow [...]
A dual or double check Trunnion Mounted Ball Valve works the same as a normal check valve. The only difference is that there are two places where water can be stopped instead of one. A check valve is used to keep the flow of liquid moving in one direction and not to back flow [...]
A butterfly valve is a quarter-turn rotational motion valve, that is used to stop, regulate, and start flow. Butterfly valves are easy and fast to open. A 90° rotation of the handle provides a complete closure or opening of the valve. Large Butterfly valves are usually equipped with a so-called gearbox, where the handwheel [...]
In standard valves, when it is given a command to open to a certain point, there is no feedback to verify that the valve has opened to that position. With a valve positioner, the command is given and the valve positioner reads the opening, verifying the position and readjusting until it gets it to the [...]
Excess of everything is bad. We have to control things so you do not have their limits. A large amount of food or food shortages certainly ruin your health. Libra has an ultimate meaning of life. Our body is all natural obstacles centers blessed. The main body has a heart valve, blood flow and make [...]
For this reason C.R.I. strong emphasis on the application of modern technologies in the development and production process.
C.R.I. Valves, a division of C.R.I. SA pumps. Ltd. today announced the launching of three valves – Butterfly Valve, Y globe valve and check valve. C.R.I. Valves provide high quality industry valves, in accordance with industry standards [...]
The global market increasingly industrial swing check valves is 248 billion this year to 374 million in 2015.The strongest growth will be electricity and sewage in East Asia. The West Asian market increased 45 percent in the period. The market in Western Europe with an increase of 6 percent during the period.
