Attention valve suppliers: valve supply cycle
Thread Content
As an example, for 100 regular gate valves, 30 stop valves, 10 check valves, and 100 ball valves at normal room temperature, what is the approximate delivery time? (How long does it take from signing the contract to completion of manufacturing?) Please don’t discuss things like type, temperature, pressure, or material size; those who are knowledgeable might be able to give some insight. Thank you
It depends on the actual situation; one needs to consider the manufacturer’s capabilities
If they are all of small diameter, they can be manufactured within a week; it’s hard to say for those of different sizes, as it depends on how many large ones there are. A conservative estimate would be within a month
1. What the poster is referring to is the normal case: if the manufacturer has sufficient stock of products produced previously that match what the poster needs, then those products can be packaged in wooden boxes and shipped within 1-2 days. This is because it takes time to prepare certificates of conformity and labels, etc. 2. If the diameters are all standard and there are no extremely large diameters, and the manufacturer has enough raw materials, then the products can be shipped after further processing, which usually takes about 5-7 days. Of course, this time depends on whether the manufacturer’s workshop is available; if it’s busy and scheduling is required, it will depend on the manufacturer’s situation. The production time is generally around 5-7 days. Valves require processes such as further processing, assembly, pressure testing, creation of labels and certificates of conformity, and packaging. 3. If the manufacturer doesn’t have any raw materials or only has some, the valve bodies need to be cast anew. It usually takes about 5-7 days for a casting factory to complete this task. If the valve manufacturer requests that the casting factory use the same material as specified, the casting process will be faster. In such cases, it takes 2-3 days from placing the order to receiving the goods. Adding the production time of 5-7 days, the total delivery time is 7-10 days. If the valve has any special requirements, the delivery time will vary. Of course, this delivery time is also related to the manufacturer’s production capabilities.
Just post the inquiry form directly. . .
It depends on the diameter. For valves with standard diameters, if they are in stock, they can be shipped right away; but for those with larger diameters that require customization, it will take a long time – at least a month
Does it take longer for PEEK-sealed ball valves?
PEEK is not used very often; the manufacturer may not have sealing materials available, so it would be necessary to order PEEK materials separately and then process them, with an estimated time of 7-10 days. Ball valves with standard diameter, pressure, and material.
Small batches: ordinary casting process, with a cycle time of around 20 days; larger batches require a longer cycle time；
Machining is divided into rough machining and finish machining ； Castings cannot avoid repair welding and grinding ； This can’t all be done in a week.
The first-pass success rate for ball valves is not very high; rework is inevitable. Moreover, with a large number of valves, there is a definite possibility of leakage in the pressure-testing housings. Unless the pressure-testing housings are rewelded and the valves are delivered to customers despite these issues, the cycle time for remelting and machining could exceed 4 weeks
