The products are widely used in water source projects, urban water supply and drainage, sewage treatment, eletric power, petroleum, petrochemical, heat supply, shipbuilding, medicine and metallurgy industries. Equipment are used for regulating or cutting off media in pipelines. Suitable media include water sewage, sea water, air, foodstuff and oil. Suitable for gear operators, electric and pneumatic control actuators.

Q:What is the difference between gate valve and gate valve? Is it the same valve?: The same, very few people call gate valve, all call gate valve.

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:How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.: Flanges for piping above DN50,DN50 (below) can be made of wire or flange (flange for pressure piping)

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 gate well?: Gate valve well: it is a irrigation network system which aims at improving water utilization and efficiency, aiming at the construction of water saving and high-efficiency agriculture as well as scientific and technological innovation as well as convenient operation and management.

Q:What is the difference between a flanged gate valve and a wire gate valve?: Threaded valve is via the wire or wire is connected with the pipeline, a small general air for the air valve, all belong to this

Q:What are the structural differences between parallel and wedge valves?: The advantages of dual gate plate is sealed and angle precision low temperature is not easy to make the wedge gate, the abrasion of the sealing surface and shim.The disadvantage is that the structure is complex, easy to stick in the dry medium, mainly the upper and lower baffles. After years of corrosion, the gate is easy to fall off. Although the single gate is sealed and angle accuracy requirements are relatively high, difficult processing and temperature change may make the gate wedge and other shortcomings, but has the advantages of simple structure, reliable use, especially to the flexible gate, can produce the micro elastic deformation to compensate for the deviation between the sealing surface angle processing, which is widely used at present.For more information about valves, please keep an eye on the valve knowledge section.

Q:What gate DH10016, AM: The first Z represents the gate valve (the initial consonant of the Chinese phonetic alphabet for the gate); the second 2 represents the drive mode of the valve, that is, electro hydraulic drive.

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 are the types and product categories of knife gate valves?: Types and classification of knife gate valves:PZ73H, PZ73F, PZ73Y manual knife gate valve: manual drive, clamp connections, rod parallel rigid single gate and valve seat sealing surface is made of hard alloy, Teflon or stainless steel body processing, nominal pressure.2PN10~16, the valve body material for carbon steel (PZ73H-10C/16C), stainless steel (PZ73F-10P/16P PZ73Y-10P/16P), with the function of slag gate valve.
