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.
Advantages | Disadvantages |
Available in large sizes | Low pressure limitations |
Can be used with slurries and viscous liquids | Slow open and close time |
Used as a shut off valve | Erosion of the seat and disk can occur |
Easy to maintain and disassemble | Poor throttling characteristics |
Inexpensive | Difficult to repair |
Inherently fire-safe (when used with a metal sheet) | Should not be used in sanitary applications |
Bidirectional |
|
Gate valves and knife valves are advantageous in applications involving slurries, as their “gates” can cut right through the slurry. They are also used in applications that involve viscous liquids such as heavy oils, light grease, varnish, molasses, honey, cream and other non-flammable viscous liquids. They are available in large sizes to better handle thick flow. However, gate valves do have low-pressure limitations, and are not optimal in applications that require cleanliness or sanitary conditions. They are excellent for use anywhere a shutoff valve is needed. When needed, they can also be used where throttling capabilities are desired, although this is not generally recommended as erosion of the seat and disc occurs due to the vibrations of the disk in throttling applications.
Gate valves and knife valves are designed to minimize pressure drop across the valve in the fully opened position and stop the flow of fluid completely. The direction of fluid flow does not change, and the diameter through which the process fluid passes is essentially equal to that of the pipe. Hence, they tend to have minimal pressure drop when opened fully.
Types
Gate valves are usually divided into two types: parallel and wedge-shaped.
The parallel gate valve uses a flat disc gate between two parallel seats, upstream and downstream. Shut-off is obtained by the free-floating seat or disk gate allow the upstream pressure to seal the seat and disk against any
unwanted seat leakage. Some parallel gate valves are designed to allow the seat to be spring-energized by an elastomer that applies constant pressure to the disk gate seating surface. In the double-disk parallel-seat type, the valve is closed by lowering the disks from the valve neck to a height equal to that of the valve seats. Once so positioned, an inclined plane mounted between the two disks converts downward stem force into axial force and presses the parallel disks firmly against the valve seats sealing the two openings. These types of valve design can accommodate asymmetric or angularly misaligned valve seats. Parallel gate valves are used in low pressure drops and low pressures, and where tight shutoff is not an important prerequisite.
Knife valves are a specific type of parallel gate valve. They have a sharp edge on the bottom of the gate to shear entrained solids or separate slurries. The through-conduit gate valves have a rectangular closure element. The closure has a circular opening equal to the full-area flow passageway of the gate valve; as the element is lowered the opening is exposed to the flow. Raising the element shuts off the flow. In this design the seating surface of the gate is in contact with the gate at all times.
Types of gate valves.
Wedge-shaped gate valves use two inclined seats and a slightly mismatched inclined gate, allowing for tight shut-off.
Disk flexibility is inherent to the split wedge design. This flexibility allows the split wedge to seal more easily and it reduces stickiness between the sealing surfaces in cases where the valve seats are angularly misaligned. The mismatched angle is also designed with some free movement to allow the seating surfaces to match with each other as the actuator forces them closed. It is also best used for handling non-condescending gases and liquids at normal temperatures, particularly corrosive liquids. Pressure-energized elastomer inserts can be installed on a solid gate to provide a tight seal. This type of disk should be installed vertically.
Solid wedges are the most common because of their simplicity and strength. They can be installed in any position, are suitable for almost all fluids, and are practical for turbulent flow.
Flexible wedge gate valves are commonly used in steam systems. The disk is one piece with a cut around the perimeter to improve the ability to match error or change the angle between the seats. Different sizes, shapes, and depths are available. For example, a shallow, narrow cut gives little flexibility but retains strength. A deeper, wider cut leaves little material at the center and weakens the disk, but increases flexibility. Flexible wedges prevent binding the gate within the valve when the valve is in the closed position. The design allows the gate to flex as the valve seat is compressed by heat from the steam in the system. The disadvantage is that water tends to collect in the body neck.Body
The body of a gate valve holds all of the operational parts of the valve. It is connected to the system with one of the mounting options below. The mounting option should be selected based on the current system mounting features and the type and size of the media.
Threaded | The valve has internal or external threads for inlet or outlet connection(s). |
Compression fitting | A sealed pipe connection without soldering or threading. As the nut on one fitting is tightened, it compresses a washer around the second pipe, forming a watertight closure. |
Bolt Flange | The valve has a bolt flange(s) for inlet or outlet connection. |
Clamp Flange | The valve has a clamp flange(s) for inlet or outlet connection. |
Union | The valve has a union connection for inlet or outlet connection(s). |
Tube fitting | The valve has a connection for directly joining tubing at the inlet and/or outlet connections. |
Butt weld | The valve has a butt weld sized connection for inlet or outlet connection. |
Socket weld/solder | The valve has a socket weld connection for inlet or outlet connection. |
Metal face seal | The valve has a metal gasket sandwiched between two fitting parts. The gasket forms a face seal on each side of the fitting. |
