rising stem wedge gate valve: Rising-stem wedge gate valve Rising-stem gate valves are used when it is important to know by immediate inspection whether the valve is open or closed and when the threads (stem and gate) exposed to the fluid could become damaged by fluid contaminants. In this design, the stem rises out of the gate valve when the valve is opened. The wedge gate ...

forged steel gate valve For gate valves which sizes are 2"(DN50) and smaller, forged steel valves are introduced. Compared with castings, forged valve bodies offer the advantages of more uniform structure, greater density, higher strength integrity, enhanced dimensional characteristics and closer dimensional tolerances. The design of forged steel gate valves are also var...

Swing check valve Swing check valves are the most common and best check valve for general-purpose use. Of all check valve designs, these valves produce the lowest pressure drop, when compared with other check valves of the same size. They feature a simple design that is easy to maintain.The swing check valve functions by allowing flow forces to move the disc from the closed p...

single-plate wafer check valve Single-plate wafer check valve This thin type of single-plate wafer check valves are swing type, that performs the same with swing check valve with much less cost. The disadvantage of this single-plate wafer check valves is, the inside diameters of the valves can only meet 60-80% of Norminal Pipe Size(NPS),  which limits the flow coefficien...

wafer type check valve Dual-plate wafer check valve Dual-plate check valves are are bonnetless and mounted between pipe flanges (wafer style). In this case, the valve includes two spring loaded half-moon shaped discs that rotate about their shaft. The actual designs of these valves vary between design models and manufacturers. Most have multiple flat seats. The dual-plate che...

tilting disc check valve Tilting disc check valve Tilting disc check valves produce slightly more pressure drop than swing check valves of the same size. These check valves have a single-piece disc without a hinge. In response to flow forces, the disc pivots about hinge pins that are located within the geometry of the disc and slightly above the center-line of the valve body....
