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:

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:Gate valve DN65 what does that mean?
- Caliber 65, refers to the size of the gate valve, you want to buy it?
- Q:Why does the fire hydrant box in the air defense area need to be added with gate valves?
- 3, protective valve should be used for stainless steel or copper gate valve or cut-off valve;4, air defense enclosure structure, the distance from the proximal end of the valve should not be greater than 200mm. Valve should have obvious signs of opening and closing.
- Q:How about the model of stainless steel gate valve?
- Stainless steel gate valve is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The expression is: Z41H-16P.
- Q:What is the standard for ductile iron gate valve set?
- The valve material name, specifications and price according to the facts that the valve rod input line.
- 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.According to the provisions of the JB/T 308-2004 valve type programming method:H== sealing surface material: Cr13 stainless steelC== body material: carbon steelW== sealing surface material: body, that is, with the same material bodyP== body material: chrome nickel stainless steel
- Q:What does the gate valve SZ45X-1.0 stand for?
- A modelModel SZ45T-1.0, especially in DN100 ~ DN300 piping, soft sealing gate valve shall be used
- Q:What's the difference between open rod gate and dark rod gate valve?
- There are several differences between the open bar gate valve and the dark rod gate valve:1, the bright bar gate valve can see the screw rod, but the dark rod can not see the lead screw;2, clear shot valve is threaded through the drive rod and the steering wheel to raise or lower the valve; dark rod valve in the switch when the steering wheel is connected with the valve stem is relatively fixed, it is through the stem of a fixed point in the rotation to drive the valve to move up and down to complete the opening and closing of the;Drive screw
- Q:What type of flange does it fit with the gate valve?
- According to the welding plate flange, flange material selection of piping material.
- Q:Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?
- the valve before the pressure measuring point, distance of valve straight pipe length is 5 times the diameter of the valve after the pressure valve, the distance is 10 times the diameter of straight pipe length.
- Q:Generally, how big is the diameter of the installation flange plate gate valve?
- Under normal circumstances:Flanged gate valves for piping over DN50,DN50 (below) can be made of wire or gate valves, or flanged gate valves (flanged valves or welded gate valves)
