GATE VALVE KNIFE DUCTILE IRON DN50-DN2000

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: 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 is the difference between gate valves Z41W-16R and Z41W-16P?: According to JB/T308P stands for Cr-Ni stainless steelR stands for Cr-Ni-Mo stainless steelCr-Ni stainless acid resistant steel has CF8, CF3, F304, F304L, which applies to the medium of work, such as nitric acid oxidation acid.Cr-Ni-Mo stainless acid resistant steel has CF8M, CF3M, F316 and F316L, which is suitable for working medium, such as acetic acid and reducing acid.

Q: What is the standard length of GB steel gate valve?: 1, product standardsGeneral purpose valves, flanged connections, iron gate valves, GB/T 12232-2005General requirements for steel valves GB/T 12224-2005"Steel flat gate valves for pipelines" JB/T 5298-91Inspection and test of valves. JB/T 9092-1999Standard for safety evaluation of drinking water distribution equipment and protective materials GB/T 17219-1998

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: What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?: Cast steel flanged gate valve 25 pressure bore 250

Q: Internal screw current limiting gate valve (Tan Gang) PN5.0 DN15/ Phi 1 Rc1/2 what does that mean?: We did thatInternal thread current limiting gate valve (Tan Gang)Body material: carbon steelPressure rating: PN5.0 = 300LB American StandardNominal = DN15 = 1/2"Phi 1 = in the middle of the gate drilling a Phi 1 hole, so that in closing there will be a certain flow, that is, the minimum flow, that is, the current limit.Rc1/2 is thread, which is the connection

Q: What is the Z15T-16C letter of the gate valve?: The Z class code indicates the type of gate valve, gate valve is the first letter of the alphabet. The gate is manual driving mode, 1 said the connection form of gate valve for connecting thread, 5 represents the structure form of gate valve for rigid single gate, T gate said lining material of copper alloy, 16 PN1.6MPa nominal pressure valve. C said the valve body material is carbon steel.

Q: Gate valve is gate valve, gate valve specifications, model code is generally what?: Valve lock plate valve, gate valve and code.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, 5- dark pole single wedge gate valve, 6- dark bar wedge gate valve 7-, dark bar parallel gate valve, parallel gate valve 9- dark bar;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber, M- Monel alloy, Tc- ceramics;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.
