1.Structure of Gate Valve Description:
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.

2. Main Features of the Gate Valve:
1, Small fluid resistance >
2, A smaller external force required to open and close
3, Unrestricted flow of medium
4, The erosion of working medium in sealing surface is smaller than globe valve when open fully.

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 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 z41t what does that mean?
According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy
Q:Stainless steel gate valve DN150 200300 weight, who knows?
Valve selection of different driving methods, connection forms, structural forms, nominal pressure, sealing surface materials, lining materials, valve body material will affect the weight of the gate valve more or less, it can not be generalized.Take my commonly used Z41H-16P (i.e. PN1.6MPa) series stainless steel gate valve as an example, and the weight of DN150/200/300 is 134/192/379kg. Of course, different manufacturers may vary in weight, but not much.I hope I can help you.
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: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:The valve safety valve check valve + + + = exposed part of a water pump adapter? Five
Generally do not require safety valve, just install exhaust valve in individual places.
Q:What do you mean by forged steel gate valves 800LB DN20 SW?
Is the forged steel gate 800LB is DN20 on SW welding pressure
Q:What are the main types of gate valves?
According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve.
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?
Because of the unsteady flow of fluid near the inlet and outlet of the valve, the measured data cannot be obtained relatively accurately.
Q:Why is gate valve or butterfly valve used for water pump?
General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment
Q:What is the difference between gate valve and gate valve? Is it the same valve?
Gate valve and gate valve are 2 kinds of valves, do not feel like a long name is the same kind, please look at Baidu maps introduced manufacturers.
