Product Description:

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. Gate Valve Z45T-10 valve uses wedge-type elastic single gate structure, apply to the temperature less than or equal 135 degrees of water, steam, oil in pipeline and other media to open and close. Main features: body is made from precision casting, sleek style seat closed plate tightly ,reaching no leakage, no sediment, circulation, smooth, open and close flexibly.
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 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.
2.  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 does gate valve Z41H-40 mean?
40 kg flanged cast steel gate valve;Flanged gate valve, 40 pressure
Q:What's the meaning of the gate valve model z41x 16Q?
According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = flange connection1 = structural form: wedge type single gateX = sealing surface material: Rubber16== pressure rating: 1.6MPaQ== body material: ductile iron
Q:What is the difference between gate valve 41h-16c and 41w-16p?
According to the provisions of the JB/T 308-2004 valve type programming method:H== sealing surface material: Cr13 stainless steelC== body material: carbon steelW== sealing surface material: body, that is, with the same material bodyP== body material: chrome nickel stainless steel
Q:The difference between gate valve and butterfly valve, as well as cut-off valve,
Valve is closed parts (RAM) along the vertical axis of the mobile channel valve in the pipeline, used primarily as a medium cut that open and close, generally do not have to do with traffic regulation, it can be used for low temperature and low pressure can also apply to high temperature and high pressure, and according to the different valve material for different media. In various types of valves, gate valve is the most widely used.Advantages: low fluid resistanceSmall torque required for opening and closingYou can use the ring road in which the medium flows in the two direction, that is to say, the medium is free of flowWhen fully open, the sealing surface is less eroded by the working medium than the cut-off valveThe structure is simple and the manufacturing process is betterThe structure length is shortDisadvantages: the overall size and opening height are larger, the space required for installation is also largerIn the process of opening and closing, there is relative friction between the sealing surfaces, and wear more easily, and even cause friction at high temperatureGeneral gate valve has two sealing pairs, to the processing, grinding and maintenance increased the number of difficultiesLong opening and closing time;
Q:What's the difference between the knife gate valve and the stop valve?
Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!
Q:What's the difference between open rod gate and dark rod gate valve?
There are several differences between the open bar gate valve and the dark rod gate valve:1, the bright bar gate valve can see the screw rod, but the dark rod can not see the lead screw;2, clear shot valve is threaded through the drive rod and the steering wheel to raise or lower the valve; dark rod valve in the switch when the steering wheel is connected with the valve stem is relatively fixed, it is through the stem of a fixed point in the rotation to drive the valve to move up and down to complete the opening and closing of the;Drive screw
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: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:How to distinguish between gate valve and 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. Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it.
Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
9- electric (drive)4- flange connection (connection)1- plain wedge single gate valve (valve structure)H-Cr stainless steel (sealing surface material)25- nominal pressure is 25 kg, or 2.5MPa;DN250- valve by 250mm
