Q: What does gate valve Z41H-40 mean?: 40 kg flanged cast steel gate valve；Flanged gate valve, 40 pressure

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: How about the model of stainless steel gate valve?: Stainless steel gate valve is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The expression is: Z41H-16P.

Q: Please tell the specific specifications and specifications of the gate valve and advise the principle of management cooperation Thank you: DN200 refers to the nominal diameter of the valve, the unit is mm, PN160 refers to the valve tolerance pressure, the unit is 1/10MPa.

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 z45h-10dn250 length of the body?: Z45h-10dn250 body length L=330mm, this valve is hidden bar, elastic seat, sealing gate valve, gate lining, lining fluorine, belong to soft seal

Q: Stainless steel gate valve DN150 200300 weight, who knows?: The weight of DN150/200/300 is 134/192/379kg. Of course, different manufacturers may vary in weight, but not much.It's not that heavy at all

Q: Fire protection gate valve from the wall how many distance there is no regulation?: 1 meters away from the wall, leaving the maintenance and replacement distance

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: The legend of gate valve and stop valve: Compared with the cut-off valve, the main advantage is that the flow resistance is small, the flow resistance coefficient of ordinary gate valve is about 0.08~0.12, while the ordinary cut-off valve resistance coefficient is about 3.5~4.5. Opening, closing force is small, the medium can flow in two directions. The disadvantage is that the structure is complex and the height is large. The sealing surface is easy to wear. The sealing surface of the valve must be forced to close the valve to achieve sealing, in the same caliber, work pressure and the same drive device, the drive valve torque is 2.5~3.5 times the gate valve. This point should be noticed when adjusting the torque control mechanism of the electric valve.The sealing surface of the stop valve contacts each other only when the valve is completely closed, and the relative sliding amount between the valve core and the sealing surface is very small, so that the wear of the sealing cover is very small. The sealing surface of the valve cover, mostly due to the spool and sealing surface before the debris, or because of the closed state is not tight, causing the medium of high-speed erosion caused by.
