6 inch Gate Valve

What is a 6 inch Gate Valve?

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.

Features of 6 Inch Gate Valve:

  • ZECO 6 inch gate valve has very reliable maintenance performance. The replaceable valve seat design ensures that later seat damage can be replaced on-site. The inverted seal design ensures online replacement when packing is replaced;
  • When ZECO 6 inch gate valve is transported, the stainless steel valve and carbon steel valve will be separately packaged, because at room temperature, when the carbon steel valve and stainless steel valve contact, will no immediate carburizing phenomenon, and the stainless steel valve has spots of corrosion is a certain period will appear. In a humid environment, if the carbon valve and stainless steel valve are stacked together is easy to produce chemical reactions, thus damaging the protective layer of the stainless steel valve, resulting in stainless steel valve rust;
  • After nearly 30 years of gate valve design, ZECO 6 inch gate valve products have stable performance and light switching torque;
  • ZECO 6 inch gate valve is all its own precision casting molds, and the casting sand is fine sand, beautiful appearance, and has clear casting characters.
