the structure of the gate valves is good for previting from corrosion, and the servive life of the gate valves is long

application:

1	face to face is according to BS5163:1986
2	falnge derilled is according to BS4504

Gate is one of the most common open/close, use of ram (namely the open-close part, in the gate opening and closing a called ram or gate, gate called ram block) to connect (full open) or truncation (seated) line in the medium.It does not allow for river closure, use should be avoided in the open gate trace, because of the erosion of high-speed flow of medium will accelerate the damage of the sealing surface.Double DE gate at the channel center line perpendicular to the gate of the one-sided as lifting movement, like gate cutting medium pipeline, so as the gate valve.

Q: Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?: Stop valve: a valve that closes the valve and moves along the center line of the valve seat. According to this form of valve movement, the valve seat opening change is proportional to the valve stroke. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation. Therefore, this type of valve is very cooperative for cutting or regulating and throttling.Advantages: in the process of opening and closing, because the friction between the valve and the sealing surface of the valve body is smaller than that of the gate valve, the utility model has the advantages of wear resistance. Second, the opening height is generally only 1/4 of the seat channel; therefore, it is much smaller than the gate valve; usually there is only one sealing surface on the valve body and the disc; therefore, the manufacturing process is better and the service is easy to maintain. Because its packing is generally a mixture of asbestos and graphite, it has a higher temperature resistance. Steam valves are normally used with stop valves.Disadvantages: as a result of the medium through the valve flow direction has changed, so the minimum flow resistance valve is higher than most other types of valves; second, due to longer travel, opening slower than the ball.

Q: What does gate valve Z44T-10-200 code mean?: The meaning of the model is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionHttp://wenku.baidu /view/5f798850ad02de80d4d84036.htmlZ = gate valve4 = connection: flange4 = structure form: double gateT = sealing surface material: Copper10 = nominal pressure: 1.0MPa, followed by no letters indicate body material: Cast Iron200 = nominal path: DN200

Q: Soft sealed gate valve and hard sealing gate valve which good?: If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.

Q: The difference and use of gate valve and stop valve: Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the 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.

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

Q: What's the difference between the knife gate valve and the 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.

Q: What are the structural differences between parallel and wedge valves?: The structure of globe valve and gate valve. What does this article introduce first?What is parallel gate valve?The sealing cover is parallel to the vertical center line, so the sealing surfaces of the valve body and the gate are parallel to each other. This gate valve is the most common double gate plate, in order to shut down, so that the valve and gate two sealing surface contact closely asked, often used in two ram double sided thrust wedge block. Thus, when the valve is closed, the double side thrust block is contacted with the bottom of the valve body and is gradually stressed.

Q: What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?: 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, 5- dark pole single wedge gate valve, 6- dark bar wedge gate valve

Q: What is an inverted seal gate valve?: The inverted sealing gate valve is provided with an inverted sealing device, and when the valve is fully opened, an inverted seal is formed, and the filling can be changed under the normal operation of the system.
