Gate valve 6 inch means the valve size is 6 inch, and in DN it is DN150.
All casting and forged parts of ZECO 6 inch gate valve, especially the body and cover two of the main pressure components, are used to strengthen the intensity of the heavy sections, although ZECO body, the cover thickness is up to standard, the heavy sections of the design can make the product more guaranteed, allowance in corrosive medium to ensure long service life of the product.ZECO pays great attention to the purchase and inspection of raw materials because ZECO knows very well that if raw materials are not strictly controlled, no matter how good the processing technology and detection means are in the later stage, they cannot turn unqualified products from the source into excellent products. Therefore, ZECO slowly moves valve products towards the route of handicraft products step by step.
