Because the jewelry valve pair was originally a stainless steel valve (it began to transform into a sanitary valve fitting in recent five or six years), now the main product is a stainless steel wide ball valve. Other wafer ball valves and sanitary valve fittings are still in the development stage. If there is no customer order, it will generally not be purchased. This is also one of the reasons for the long delivery cycle.
In jewelry valves, special attention is paid to the details of stainless steel valves in production. General valve factory only requires the functionality and sealing of stainless steel valves. On the other hand, jewelry valves require lathe workers to chamfer each machined surface during machining. In the words of general manager Lin, "not chamfering for three years is a waste of time." In the drilling and milling part, a special person is specially assigned to polish the burr of each stainless steel valve fitting. The jeweler joked that these products were produced as real jewels. Therefore, the excessive pursuit of product details has created one of the reasons for the long delivery cycle.
The efficiency of jewelry valve assembly is particularly low. Four people from other manufacturers can complete the assembly in one day, and the workers of jewelry valves need more than eight people to complete it. Sometimes in a hurry to grab goods. Take the assembly of stainless steel ball valve as an example. Usually manufacturers put all the accessories together, as long as they can be installed, it will be OK. Unlike jewelry valves, they need to pair the stem with the ball valve. If the valve stem is stuck in the ball groove, the ball will not automatically fall off and pass, otherwise different valve stems will be paired until it passes. According to the assembly master, this is to ensure that after the valve is installed, it will not be stuck when opening or closing the valve, and it can also prevent the valve stem from hitting the ball valve to deform the ball groove and seal it loosely. So this is also one of the reasons for the long delivery cycle.
