1.Structure of the 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.

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 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 is the soft seal gate valve?
Commonly used soft sealing gate valve model is divided into: Z45X and Z41X, the difference is that the Z41X is the Ming bar, and Z45X is dark rod.Matters needing attention in packing and transportation of soft sealing gate valve:Soft sealing gate valve before transport, should use the rope to tie up the small caliber.Before transportation, the lighter sides of the valve should be sealed.For larger caliber soft sealing gate valve, it should be used to carry out simple packing, it can better prevent the valve in the process of transportation damage.
Q: What does gate valve Z44T-10-200 code mean?
The meaning of the model is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionHttp://wenku.baidu /view/5f798850ad02de80d4d84036.htmlZ = gate valve4 = connection: flange4 = structure form: double gateT = sealing surface material: Copper10 = nominal pressure: 1.0MPa, followed by no letters indicate body material: Cast Iron200 = nominal path: DN200
Q: Gate valve Z41H-16Q generally used for what place?
Commonly used in petroleum, chemical systems, especially in long-distance pipelines of petroleum and natural gas.
Q: The difference and use of gate valve and stop valve
Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.
Q: What is the standard for ductile iron gate valve set?
Clear shot valve installation, is still under way of connection and specifications set "water supply and drainage, heating, gas engineering" or "industrial engineering" pipeline register quota corresponding specifications and installation methods of connecting the valve installed valve section.
Q: Which is more expensive, bronze gate valve or brass gate valve?
The casting and workability of brass are much better than that of stainless steel, especially the valve with more complicated internal cavity.
Q: What is the difference between Z41X gate valve and Z45X gate valve?
2 kinds of valve function, there is no difference.Nothing more than a one with a bright bar. One is a dark pole.Dark pole is cheaper.Everything else is the same. Contact me if you need another valve. Zhejiang Futai Valve Co., ltd.. The contact picture is in the head.
Q: What is the allowable leakage rate of the gate valve D?
In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.
Q: What is wire feed gate valve? What do you say in French?
It should be the wire gate valve. Refers to the valve body with internal thread or external thread, and pipe thread connection. Also called thread valves, threaded valves, valves within the toothFlange gate valve is connected to the flange gate valve, this connection is the most common wayThe main difference is the connectionI only know their English, I'm sorry I can't help youBox thread valveFlange valve
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
