A knife edge gate valve is a valve that is used to control the fluid media by either stopping its flow or by limiting it to suit the desired flow operation. Pressure loss is a major problem that is produced by the usage of valves and the gate valve allows a straight-through unhindered passageway for the fluid media thereby leading to minimal pressure drop due to the valve. Unlike the Gate valves, the gate valves allow unobstructed flow and thus, also a passage for the cleaning operation of the pipe, when it is needed. However, on the flip side, the gate valves are slower to operate than the quarter-turn Gate valves. Therefore, in normal operations, the gate valves are operated either in fully closed or fully open mode. Therefore, in most applications, a manual gate valve is used because gate valves are operated intermittently. Gate valves are beneficial in applications that involve the movement of slurries and are also useful in applications involving the transport of viscous liquids such as heavy oils, varnish, light grease, honey, cream, molasses, and other non-flammable viscous liquids. They are offered in big dimensions to handle viscous flow efficiently. Although it is not recommended, the gate valves can be used for throttling applications. Parts of Gate Valves
There are many parts comprising the gate valve. To get a good and clear idea, let us have a look at the following table for the list of parts and their important functions. Working of the Gate Valve: A gate valve works very similarly to the normal working of any other valve. To operate the valve, the hand wheel needs to be operated, or using the actuators, the stem is either raised up or down. When the gate is lifted, it releases the inlet to the outlet permitting an unobstructed passage for the fluid media to flow. When the gate is dropped, it closes and wedges the media flow. The association between the gate's vertical travel and the flow rate is nonlinear for a gate valve, with the utmost changes happening near-complete closure position. You should make sure to choose the best Gate Valves manufacturers that would serve your purpose. There are many types of gate valves, some of which are listed below, -Knife gate valve -Wedge gate valve -Parallel slide gate valve -Slab gate valve -Parallel expanding gate valve There are many advantages of using a Gate valve over other valves. A few of the advantages include (i) Low loss of pressure across the valve. (ii) They are bi-directional and permit uniform linear flows. (iii) No residues are left in the pipes. (iv) Gate valves can endure higher pressures compared to butterfly valves (v) It avoids water hammers because the wedge has a slow operation. However, it also has disadvantages such as low operational speed, erosion of seat and gate if partially operated, and more expensive due to its large size.
