Ball Valve

Ball Valve

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. There are general body styles of ball valves: single body ball vavle, three-piece body ball vavle, 3 ways ball valve,4 ways ball valve,split body ball vavle, top entry ball vavle, and welded ball vavle with trunnion type ball valve and floating type ball valve, The difference is based on how the pieces of the valve—especially the casing that contains the ball itself—are manufactured and assembled. The valve operation is the same in each case.

Butterfly Valve

Butterfly Valve

A butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe;There are different kinds of butterfly valves, Such as: concentric butterfly valve,doubly-eccentric butterfly valve ( high-performance butterfly valve),triply-eccentric butterfly valve(triple offset butterfly valve),flange type butterfly valve,wafer type butterfly valve,lug type butterfly valve,each adapted for different pressures and different usage.

Gate Valve

Gate Valve

A gate valve, also known as a sluice valve, is a valve which opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can be parallel, but are most commonly wedge-shaped. The type of gate valve like :Wedge gate valve,slab gate valve,flange gate valve ,butt welding gate valve,socket welded gate valve,electric gate valve,expanding gate valve,high pressure gate valve,knife gate valve.

Globe Valve

Globe Valve

A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline,consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. This has an opening that forms a seat onto which a movable plug can be screwed in to close (or shut) the valve. Typically, BS1873 globe valve,angle pattern globe valve,plunger type globe valve,needle globe valve,electric globe valve,high pressure globe valve,bellow seal globe valve, Y pattern globe valve,automated globe valves use smooth stems rather than threaded and are opened and closed by an actuator assembly.

Check Valve

Check Valve

A check valve, clack valve, non-return valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications such as: Swing check valve,lift check valve,ball check valve,diaphragm check valve,tilting disc check valve,clapper check valve,butterfly check valve,stop check valve,in-line check valve,pneumatic non-return check valve,flange check valve,wafer check valve,lug check valve.
Heart valves are essentially inlet and outlet check valves for the heart ventricles, since
the ventricles act as pumps.

Plug Valve

Plug Valve

A plug valves are valves with cylindrical or conically tapered "plugs" which can be rotated inside the valve body to control flow through the valve. The plugs in plug valves have one or more hollow passageways going sideways through the plug, so that fluid can flow through the plug when the valve is open. Plug valves are simple and often economical.the type have as like : Lubricated Plug Valve,Non-Lubricated Plug Valve,Lift-type plug valve,Elastomer sleeved plug valve,Fully lined plug valve,Eccentric Plug Valve,Expanding Plug Valve,3 ways plug valve,4 ways plug valve.Also if the plug valve is "locked" from being in the open or closed position for an extended amount of time lubricant can be added through the greaser with the valve in service.
