The pressure of the fluid passing through a system opens the valve , while any reversal of flow will close the valve. Exact operation will vary depending on the type of Check valve mechanism.

A lift- check valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps motion of the disc on a vertical line, so the valve can later reseat properly. H-V014-E-14】 Ball Check Valve , True Union Ball Check Valve and Ball Foot Valve This user’s guide contains very important information for the proper installation, maintenance and safe use of an ASAHI AV Product.

Most types are not operational, and therefore do not have control handles. A back-flow preventer, of the type often found on outdoor faucets (hose bibbs) and on lawn sprinkler systems, is one example of a check valve. In our discussion of the world of maritime supplies, a detailed listing of valves is a necessary procedure. It is also used in control valves are operated by hydraulic or pneumatic cylinders.

Rotary Stem This is a commonly used model in ball, plug, and Butterfly valves. A quarter-turn motion of the stem open or close the valve. In the main Menu Valves you will find some links to detailed (large) images of Rising and NON Rising Stem valves. Gate Valves are widely used in fluid-handing systems for flow control, Typical gate valves are designed to be fully opened or closed.

When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss. A globe valve , different from ball valve , is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.

These valves are often designed for safety reasons, to prevent backflow and to ensure that someone operating a system knows which direction fluids and gases are flowing in. Check valves can also be used for tasks like creating leak tight seals, which can be an important safety or convenience future. The images are not to scale but are drawn to represent the proportions of a valve in the middle of the size range. These images should therefore not be used for determining valve clearances. Dimensions on Sales Drawings should be used for that purpose (refer to the Val-Matic Engineering Catalog).

Rotational motion valves used to start, stop or throttle flow. The valve uses a ball shaped disk with a hole in it. When the valve is opened the hole of disk is turned in-line with the direction of the flow. The DUO CHECK valve LUG type covers the bolt along the entire length of the body. LUG type valves are supplied in scallop to keep the weight as low as possible, thereby minimizing the cost.

For more information contact the company. In such a design, a wedge slides cross a general passageway in order to control fluid flow (like a sliding gate - hence, the name). A wide variety of valves images options are available to you, such as free samples, paid samples.

There are 2valves images suppliers, mainly located in Asia. Pinch valves are best suited for handling slurries and fluids having suspended solids.
