Packaging & Shipping

Our conventional packing is wooden case packing, we go to great lengths to ensure delivery within 30 days after receipt your order.

Q: For example, the knife gate valve, PZ73X-10C, DN50 torque is 5, torque is what role? What units?: The opening moment (torque) is the force or torque that must be applied when the valve is opened or closed. Need to open and close the valve when the sealing pressure than the formation of closed and valve seat sealing surface between the two, but also to overcome between the stem and the packing between screw stem and the nut, the valve stem friction end bearing and other friction parts. Therefore, certain closing force and closing torque must be applied, and the required opening and closing force and opening and closing torque during the valve opening process are varied, in which the maximum value is at the closing instant or the initial opening moment. Design and manufacture of valves, should strive to reduce the opening and closing force and opening and closing torque.The open torque can be obtained by means of calculation or measurement, and can be obtained by hand torque measurement.

Q: What kind of industry does valve belong to?: Valve is the valve, regardless of other sectors

Q: and today the boss told me that I would like to do a valve of the commodity inspection information, and nothing else to me, which master taught meI am a professional intern, our company is doing the valve outlet, today my boss asked me to do a valve inspection data, what other data are not for me, which foreign trade master teach me ah, depressed ah ah ah???: First of all, you have to check the HS encoding of your product.The corresponding HS code will have a regulatory condition followed by different regulatory conditions that mean different procedures (or certificates), such as what you call "B".What aspects must be examined in commodity inspection?Different products to implement different inspection and quarantine methods, the general is to do a customs clearance on the OK. The products you mentioned above may not need to do customs clearance (see what kind of valve you are, so you'd better check the conditions again)Is commodity inspection agent or business enterprise? Do you need to check every export?Generally not many agents are on the line, and if the HS regulatory conditions have to do customs clearance, then each time to do.Is there any standard or basis for inspection? Where can I find out the knowledge in this area?

Q: How can you replace the other valve when the main valve is not closed and no water is stopped?: You really want to go to the big water to fix the valve and be prepared for the follow-up, just in case

Q: What are the advantages and disadvantages of this method? Are there any other ways to adjust the flow rate?: With the advantages of the pump outlet valve adjustment, 1, you can control the pump outlet pressure, 2, you can control the motor current is not more than the process conditions, 3, control motor power, to ensure the normal operation of the pump.

Q: What does valve DN50/80 mean?: DN50/80 refers to the size of the valve. That is, the circulation diameter is 50mm/80mm.

Q: What items and detailed procedures should be inspected for valve size inspection?: The American Standard (American Society of mechanical engineers ASME B 16.10-2000). Internet access can be downloaded, such as free standards to share and download sites. If you need any other valve standard, send me the mailbox.

Q: Tell me the exact address, or the phone number in the market. Where is the industrial zone (the valve) in Hefei? Please help, thank you: At the intersection of Mingguang Road and Shengli Road, the southwest side is all made of valves

Q: How big valves are used in a DN159 pipe?: DN159 is the valve with the DN150 in the outer diameter of the pipe.The valve size of the pipeline is classified by nominal diameter:1, the small diameter valve: nominal diameter DN = 40mm valve.2, medium diameter valve: nominal diameter DN from 50 to 300mm valve.3, chase diameter valve: nominal valve DN for 350 ~ 1200mm valve.4, large diameter valve: nominal diameter DN = 1400mm valve.The components of the valve must be handled following process before they are assembled:1, according to processing requirements, some parts need polishing, surface processing burr can not be;2. All parts are degreased;3, after degreasing, pickling and passivation, the cleaning agent does not contain phosphorus;4. After pickling, rinse with pure water, no residue of medicament, and carbon steel parts shall be omitted;5, one by one parts with non-woven fabrics dry, not cable, hair and other retained parts of the surface, or with clean nitrogen drying;6, with non-woven fabrics or precision filter paper, stained with pure alcohol, wipe parts by one, until there is no dirty color.
