Product Description:

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. 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.

2.Main Features of the Gate Valve:
• Valve body cavity using non-toxic epoxy resin,both inside and outside flashboard completely is coated with rubber
• Free of water pollution
• High manufacturing accuracy
• High strength
• Environmental protection and energy saving
• Good visual effect

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:HVAC design, why is less than DN50 of pipe gate valve and cut-off valve,
Heating butterfly valve is flanged connection. Pressure capacity is stronger than gate valve and stop valve. For connection safety, do not use gate valve and stop valve wire connection
Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
Cast steel flanged gate valve 25 pressure bore 250
Q:About fire valve is gate valve or butterfly valve problems?
Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.
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:Internal screw current limiting gate valve (Tan Gang) PN5.0 DN15/ Phi 1 Rc1/2 what does that mean?
We did thatInternal thread current limiting gate valve (Tan Gang)Body material: carbon steelPressure rating: PN5.0 = 300LB American StandardNominal = DN15 = 1/2"Phi 1 = in the middle of the gate drilling a Phi 1 hole, so that in closing there will be a certain flow, that is, the minimum flow, that is, the current limit.Rc1/2 is thread, which is the connection
Q:What is the difference between the copper gate valve and the ordinary material gate valve?!
The material of general gate valve is cast iron, and the copper gate valve should be used in special requirement.
Q:What is the difference between the cut-off valve and the gate valve?
What is the difference between gate valve and stop valve?:Gate valve and globe valve structure is different, the valve structure for hand wheel, with the stem rotating together to do the opening and closing movement. Valve structure is rotating handwheel, stem do lifting movement. The flow is different, the gate valve requires full open or full closed state, the cut-off valve does not need. The valve has the flow direction requirements, and the gate valve has no inlet and outlet requirements!Sealing performance comparison:Valve length is shorter than the cut-off valve, higher than the cut-off valve, the valve should pay attention to the installation of high elevation. The gate valve can be tightly closed with the sealing surface by the pressure of the medium so as to achieve the effect of not leaking.
Q:What does gate valve DN80-PN16-QT450 mean?
DN80 means: liquid, internal thread connection, the valve sealing surface material for rubber, seat sealing surface material for lining adhesive, nominal pressure of 10 kg / cm2, nominal diameter of 80mm Iron Butterfly valve.
Q:Function of gate valve
Valve strengths: (1) fluid resistance is small, due to the valve inside the valve channel is straight, and the medium flow through the valve does not change its direction of movement, so the fluid resistance is small. (2) the opening and closing moment is small, opening and closing more effort, as the gate valve opening and closing, the direction of movement of the gate and the direction of the media movement vertical, compared with the cut-off valve, valve opening and closing more effort. (3) the direction of the movement of the media is not limited, no disturbance, no pressure reduction, the media can flow in any direction from both sides of the gate valve, and all can achieve the purpose of use, more suitable for the direction of the movement of the medium may change in the pipeline. (4) the length of the structure is relatively short, because the gate of the gate valve is vertical inside the valve body, and the stop valve clack is horizontally placed in the valve body, so the length of the valve is shorter than the cut-off valve. (5) the sealing function is good, when the full opening, the sealing surface is less eroded. (6) when fully open, the sealing surface is less eroded by the working medium than the cut-off valve. (7) the shape is relatively simple, the forging technology is good, and the scope of application is wide.
Q:What is the difference between gate valve Z41T and Z45T?
Valve Z41T and Z45T difference is that "41" is dark rod, that is, the screw is not out of the turbine,"45" is the bright rod, that is, the screw out of the turbine.Common points are copper sealed gate valves.
