1.Structure of Gate Valve Description:
A gate valve, also known as a sluice valve, is a valve that 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 form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. For extremely thick fluids, a specialty valve often known as a knife valve is used to cut through the liquid. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that flow rate does not change evenly with stem travel. Also, a partially open gate disk tends to vibrate from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow. 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.
2. Main Features of the Gate Valve:
• Valve body cavity using non-toxic epoxy resin,both inside and outside flashboard completely is coated with rubber
• Free of water pollution
• High manufacturing accuracy
• High strength
• Environmental protection and energy saving
• Good visual effect

5.FAQ
1. What's are the characteristics of gate valve?
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 form a wedge shape or they can be parallel.
2. What is the work principle of gate valve ?
The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry.
3. What is the structure?
Bonnets provide leakproof closure for the valve body. Gate valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.
- Q: What gate DH10016, AM
- The first Z represents the gate valve (the initial consonant of the Chinese phonetic alphabet for the gate); the second 2 represents the drive mode of the valve, that is, electro hydraulic drive.
- Q: What does gate valve Z41H-40 mean?
- 40 kg flanged cast steel gate valve;Flanged gate valve, 40 pressure
- Q: What do you mean by gate valve type RVHX-0150-10 and Z45X-16Q?
- Z45x-16q, Z means gate valve, 4 means flange connection, 5 refers to dark rod gate valve, X means rubber seal, 16 refers to nominal pressure 1.6MpaRVHX means manual gate valve, 150 refers to the caliber of DN150, and 10 indicates nominal pressure of 1.0MPa
- Q: What are the features and uses of the gate valve?
- 1) advantages: sealing performance than the cut-off valve, the fluid resistance is small, open and close more effort, full sealing surface by the erosion of media, media flows from the restrictions, with double flow, small structure length, wide application range. 2) disadvantages: high size, open need a certain space, opening and closing time is long, in the opening and closing, the sealing surface is easy to erode and scratch, and the two sealing pairs bring difficulties to the processing and maintenance.3) use: gate valve is generally used in the caliber of DN15-1800mm pipes and equipment, and its dosage is great, mainly cutting off function, not allowed to throttle.
- Q: Gate valve type Z40Y, Z40H letters - what does that mean?
- According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange0== structure: wedge type elastic RAMY== sealing surface material: hard alloyH== sealing surface material: Cr13 stainless steel
- Q: Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
- 2, soft sealing gate valve at the bottom of the pit. No accumulation of slag material, valve opening and closing of the failure rate is low;
- Q: What does gate valve DN80-PN16-QT450 mean?
- DN80 means: liquid, internal thread connection, the valve sealing surface material for rubber, seat sealing surface material for lining adhesive, nominal pressure of 10 kg / cm2, nominal diameter of 80mm Iron Butterfly valve.
- Q: What gate valve is the J41H-150LBDN100 gate valve?
- J41H-150LBDN100 is not a gate valve, it is a API stop valve.API valve can only medium one-way flow direction when installing. Its structure length is larger than gate valve, and the fluid resistance is large. The reliability of sealing is not strong in long-term operation.Also called cut-off gate valve is the most widely used as a valve, it is popular is because the process of opening and closing the sealing surface friction between the small, more durable, highly open small, easy manufacture, convenient maintenance, not only for low pressure, but also suitable for high pressure.
- Q: Fire protection gate valve from the wall how many distance there is no regulation?
- 1 meters away from the wall, leaving the maintenance and replacement distance
- Q: What is the difference between gate valve 41h-16c and 41w-16p?
- The difference between 41h-16c and 41w-16p is that the material of the valve body and the material of the sealing surface are different.
