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:Gate valve Z41H-16Q generally used for what place?
Commonly used in petroleum, chemical systems, especially in long-distance pipelines of petroleum and natural gas.
Q:The difference between cut-off valve and gate valve
Structurally, the gate valve for the gate, down to the front and back seat seal; globe valve with spherical, taper and flat spool, down to the valve seat seal. Functional stop valves are generally used for pressure flow control. Gate valves are used for isolation.
Q:What are the specifications of the gate valves? Does the work pressure need to be marked separately?
According to domestic valve model standards, the valve model is by the valve type, gate valve drive mode, gate valve connection, gate valve structure, sealing material, valve body material code to indicate.1, gate valve type code named Z;2, gate valve drive mode code by letters, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out;3, gate valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, the valve structure of code, 0- flexible wedge, 1- rod single wedge gate valve, 2- rising stem wedge gate valve, 3- parallel single gate valve, 4- parallel double gate valve,
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:How to distinguish between gate valve and cut-off valve?
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:TitleThe difference between gate valve, butterfly valve and stop valve
The gate (gate valve) is a 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 valve. The 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 valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex
Q:Gate valve z41t what does that mean?
According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy
Q:Generally, how big is the diameter of the installation flange plate gate valve?
Under normal circumstances:Flanged gate valves for piping over DN50,DN50 (below) can be made of wire or gate valves, or flanged gate valves (flanged valves or welded gate valves)
Q:What does gate valve DN200PN160 mean?
