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.

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 wire feed gate valve? What do you say in French?
Point to 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 connection
Q:What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?
7-, dark bar parallel gate valve, parallel gate valve 9- dark bar;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber, M- Monel alloy, Tc- ceramics;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: for electric, flange connections, Ming Liang wedge double gate, the sealing surface material directly processed by the body, nominal pressure PN0.1MPa body material for gray cast iron gate valve: Z942W-1 electric wedge double gate valve
Q:What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?
Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel
Q:What does gate z41t-10 150 mean?
According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150
Q:Gate valve DN65 what does that mean?
Nominal diameter 65 gate valve.This depends on the material of your valve, it is new material, it is to use the outer diameter to do the standard, specifications with 63.75, and so on, because the new material is welded or coated with glue connection. So use the outside diameter as the standard, or the gap will appear.There is also the metal standard, according to the nominal diameter, or flange connection flange and skein skein are industry specifications.When it comes to the end, it must be between the pipe and fittings must be connected.
Q:The difference between flanged gate valve and common gate valve
Flange valve: English name; Flange Gate Valve is the gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.Ordinary gate valve: mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Gate valve applies to pressure, temperature and caliber range is great, especially for medium, large diameter pipesThe most important difference: flange gate valve and ordinary gate valve is different, flange gate valve quality, durable, easy to install, but higher prices, generally used for large pipelines. Ordinary gate valves are used for small caliber, easy to change places.
Q:Is the gate valve clockwise or closed?
Usually it's off. There are some special occasions. It is said that the plane uses a lot of counter
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:Notes on flat gate valves
internal structureThe 1 seat O ring seal and preload floating seat structure, so that import and export of two-way valve seal plate; and the structure of the normal valve opening and closing torque only 1/2, can easily open and close valves2. when fully open, the channel is smooth and straight, the flow resistance coefficient is extremely small, and there is no pressure loss. The pipeline can be cleaned through the hair bulb3 the packing structure with the ability of self sealing, without frequent adjustment, opening and closing very lightweight, and reliable seal, the stuffing box is arranged at the auxiliary seal oil into the structure, absolutely reliable sealing performance, thereby achieving zero leakage; solve the shortcomings of the general valve packing leakage of the most vulnerable4., when the flat gate valve is closed, it can automatically unload the inner cavity high pressure, and ensure the safe use5., fully enclosed structure, good protection performance, can adapt to all-weather requirements6., the valve seat sealing structure should be elastic, preload, upper and lower sealing seat at the same time sealed structure. The valve seat and the seal are always face to face sealed.The 7. seat has self-cleaning function and is free of direct airflow during valve opening or closing. The seat shall be made of lubricated, non wearing material.8. valve actuator failure will not affect the other parts of the valve, maintenance and replacement work can be carried out without removing the valve.9. yoke sleeve aluminum bronze yoke sleeve with pin type thrust bearing to minimize operation torque.10. stem - thread length until bracket; dowel and spot welding; stability.11. pressure seal - simple construction, with sectional retaining rings and silver plated low carbon steel gaskets, helps to remove and achieve the best bonnet seal.12. seat ring - welded seat ring is perpendicular to the flow channel and is easy to maintain.
Q:What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve
Yes. Globe valves and gate valves are indeed common in certain piping and operating conditions.
