High pressure gate valves

  1. 1. Why Use High Pressure Gate Valves
  2. 2. * Safe drinking water is provided to homes and offices through wellengineered system of pipes and valves which control the entiredistribution of water.* There are different types of valves used for various purposes. Gatevalves are mainly used to open and shut the straight line flow of anytype of liquid including water.* These valves are mainly used in high pressure areas to either stop theflow of water or to start it. It is never used to regulate the flow of water.* Gate valves are known for its durability, rugged construction,performance and accuracy. These devices are in great demand due toits cost effectiveness and easy installation.
  3. 3. Various Types of Gate Valves - Designs, Sizes And Materials * Gate valves are available in different designs and sizes to suit different purposes.These high pressure valves are classified according to its design and structure. There arebasically two types of gate valve which include the rising stem valve and the nourishing orthe non rising stem valve. * Gate valves are available in different designs and sizes to suit different purposes.These high pressure valves are classified according to its design and structure. There arebasically two types of gate valve which include the rising stem valve and the nourishingor the non rising stem valve.
  4. 4. Rising Stem Gate ValveIn it the valve rises when the stem is rotated to open. So it is quiteeasy to identify the position of the valve.Ample amount of space is required for these types of devices. It isnot suitable for underground applications.
  5. 5. Non Rising Stem Gate Valve This valve is ideal for all types of spaces and applications.Different bonnets are also used for these devices. Screw in bonnet isone of the smallest devices used for simple applications. Bolted bonnetsare essential for high pressure applications as it is considered to be safeand efficient. Union style bonnet is another variety of gate valve designwhich is used in areas which requires regular inspection.
  6. 6. High Pressure Gate Valves With DesignsHigh pressure gate valves are also classified according to its designs which include the parallel valves and the wedge valves.
  7. 7. Wedge Gate ValveSub divided into flexible gate type, single gate type and the dual gate type.
  8. 8. Parallel Gate ValvesThis valve can also be divided into double and singleplate types.
  9. 9. Applications of Slide Gate Valves In the earlier days slide gate valves was used in steam engines but nowadays it is used in automobiles for proper functioning of the engines. There are devices which aredesigned specifically for cement, coal and fly ash applications. Most of these devices arein-built with self cleaning valves. Some of the most important applications and uses arementioned below.1. Control of powder flow: These devices are mainly used to control the flow of powder which includes cement, coal and other granules such as plastic pellets.2. Dust collection: Another important application of the slide gate valves include the dust collection feature.3. Shut off: These devices are mainly used to shut off the flow of products from the outlets of the storage cans, conveyors and other types of discharge bins which are used to store dry bulk materials.4. Dust tight transition: Most of the devices are equipped with dust frames which prevent the accumulation of dusts.5. Adjustable seals: The valves are inbuilt with adjustable seals which eradicates the need for constant seal replacements. It is easy to adjust the seals from the outer side of the valve frames.6. Efficient and fast: These are also known for its precise accuracy, efficiency and fast action.7. Suit all application: The devices are known to be versatile and suit different types of applications.
  10. 10. Ball valve Two elastomeric O-rings provided with backup in PTFE perform a double stembarrier to the fluid. The outer O-ring can be replaced with the valves under pressure.
  11. 11. Butterfly valveOptional “trim” features allow valves to accommodate a wide rangeof chemical, food and pharmaceutical (sanitary) applications.
  12. 12. Control Gate Valve The opening or closing of control valves is usually doneautomatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuatorbased on electric, or pneumatic signals.
  13. 13. Globe Gate ValveA globe valve is a type of valve used for regulating flow in a pipeline, consisting of amovable disk type element and a stationary ring seat in a generally spherical body.
  14. 14. Needle Gate Valve A needle valve is a type of valve having a small port and athreaded, needle-shaped plunger. It allows precise regulation of flow, although it isgenerally only capable of relatively low flow rates.
