Product Description:

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 meaning of socket welding gate valve A105, D&S:STLT, STEM:13Cr, CL800, SW, AP1602, BB-BG-OS&Y?
Body material: A105Sealing surface material: STLStem material: 13CrPressure rating: CL800Connection: SWImplementation criteria: AP1602BB-BG-OS&Y: plain rod support, bolt connection, flange valve cap.
Q:What does "Z45W-10T" mean?What does each letter stand for?
For type PN10 Z45W Brass Gate ValvesZ is the valve type code, which represents the gate valve;Driving mode is hand wheel (code name omitted);4 is the connection form code, which represents the flange;5 is the gate valve structure form code, represents for the dark pole wedge rigid single gate;
Q:What are the main types of gate valves?
According to the different materials for carbon steel valves, forged steel valves, stainless steel valves, cast steel valve, iron gate, ceramic valve;
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.com/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:What do you mean by "2" and "200 CF8M"?
CF8M is stainless steel, and 2 is caliber 50200 and should also be bore
Q:Is the axial force and torque of the wedge gate valve the same?
See where you are, it is better to compare it: wedge type single gate valve features: a structure more flexible, gate valve is simple, sealing performance better than flexible gate valve or double gate valve.
Q:What type of flange does it fit with the gate valve?
This depends on the type of gate valve, valve standards are marked with matching flange standards. Different types of flanges for different gate valves are also different.The flange of General GB gate valve is GB/T9113 series.
Q:Pump adapter generally includes what accessories?
There is integration now.Pump adapter SQ100. All contain.
Q:What's the difference between a soft seal gate valve and a hard sealed gate valve?
It uses the elastic material of the gate, and uses the elastic material to produce the micro deformation compensation effect. It can achieve good sealing effect. Soft sealing gate valve has the advantages of light switch, reliable sealing, good elasticity memory and long service life.Hard sealing surface of the gate valve for cast iron or stainless steel, open and close resistance is small, no flow, but poor sealing performance.
Q:How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.
Specifically, look at the pressure of the pipeline, the environment is not big, if large with flange connection, usually hoop or wire can be connected.
