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.

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:The difference and use of gate valve and stop valve
Standard light valve professionals to answer for you, gate valve refers to the closure of parts (gate) along the central line of the vertical direction of moving valve. The gate valve is mainly used for cutting in the pipeline. The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.Minor force needed for opening and closing.
Q:What does the gate valve 150# mean? Is it stress PN? What's that, PN16 or?It's better to have some specific links, thanks!
150Lb (American Standard pressure value corresponding to the PN2.0)
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:Which is the most expensive, check valve and gate valve?
In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124
Q:What gate valve is the J41H-150LBDN100 gate valve?
Its closing principle is to rely on the valve bar pressure, so that the valve sealing surface and seat sealing surface close together, to prevent the circulation of media. The cut-off valve is divided into three kinds: straight through type, right angle type and direct current type oblique stop valve.
Q:What are the specifications of the gate valves? Does the work pressure need to be marked separately?
Gate valve code Z, such as GB gate valve Z41H-16. Front is the valve type, and the back 16 represents the pressure of 16 kg, 1.6MPa
Q:Please tell the specific specifications and specifications of the gate valve and advise the principle of management cooperation Thank you
There is mail sent me, send you a specific
Q:What is the Z15T-16C letter of the gate valve?
The Z class code indicates the type of gate valve, gate valve is the first letter of the alphabet. The gate is manual driving mode, 1 said the connection form of gate valve for connecting thread, 5 represents the structure form of gate valve for rigid single gate, T gate said lining material of copper alloy, 16 PN1.6MPa nominal pressure valve. C said the valve body material is carbon steel.
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.
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
