As one of the pressure control equipment for flow control pipelines, the quality of valve body castings is the most important for valve life and personnel and environmental safety, especially in the field of high temperature and high pressure conditions. Therefore, valve castings are always the first accredited material for critical customers to prequalify before approving the valve manufacturer as a qualified supplier.
In order to control the quality of products from the source, Yongsheng has wholly established a casting base: a sand casting casting base using resin sand casting technology and a precision casting casting base using dewaxing precision casting technology. And equipped with a dedicated testing facilities: spectrum analyzers, nondestructive testing equipment, mechanical performance testing equipment. Can guarantee the entire process of valve production, thus ensuring the final product quality, delivery time, and competitive prices.
The introduction of advanced technology production of electrical and electronic components, resin sand mixer using advanced PLC programmable logic controller automatic control, the operation of the equipment set up a reliable interlock protection system, so that the entire line of equipment operation, monitoring is simple, sufficient protection and control.
Has a very complete investment casting production equipment, machining equipment and advanced physical and chemical analysis, testing equipment, to meet the different levels of customer demand for product requirements and physical and chemical properties, non-destructive testing of the full range of requirements.
