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: The difference and use of gate valve and 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 else, P54140V, 170V? What do they mean?: P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar

Q: How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.: According to user requirements, DN15 also has flanges, in general, DN50 or more are flanges

Q: Z41T one 10 gate valve and Z44T one, 10 gate valve difference: Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa

Q: Gate valve type Z40Y, Z40H letters - what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange0== structure: wedge type elastic RAMY== sealing surface material: hard alloyH== sealing surface material: Cr13 stainless steel

Q: What's the difference between open rod gate and dark rod gate valve?: 4, the dark pole gate valve height smaller size; Ming rod gate valve requires a larger installation space;5, the structure of the rod gate valve is beneficial to the lubrication of the valve stem, and the degree of opening and closing is obvious. The stem thread of the dark rod gate valve is not only unable to lubricate, but also directly accepts the medium erosion and is easy to damage. Therefore, the open bar gate valve is used more widely

Q: Is the gate valve clockwise or closed?: Usually it's off. There are some special occasions. It is said that the plane uses a lot of counter

Q: Does the tap belong to a stop valve or a gate valve?: Most taps are stop valves:1, gate valve (gate valve) is a headstock ram, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed doors, discomfort pumpsparameters vary, usually 5 degrees is not high, medium temperature is 2 degrees 52'. To improve its manufacturability, make up for the deviation of the angle of the sealing surface during processing. This gate is called an elastic ram.2, valve (stop, Globe, Valve) of the opening and closing parts are plug shaped valve, sealing surface is flat or sea cone, the valve along the center line of the valve seat in a straight line movement. Stem form of exercise (generic name: dark bar), but also lift rotating rod can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. Therefore, this type of shut-off valve is very suitable for cutting or regulating and throttling. 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.The stop valve is an ascending stem type, and the handwheel rotates and rises along with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!

Q: What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?: Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.

Q: What is the difference between gate valve 41h-16c and 41w-16p?: The difference between 41h-16c and 41w-16p is that the material of the valve body and the material of the sealing surface are different.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
