Description of 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, cover thickness is up to standard, but 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:

1. 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;

2. When ZECO 6 inch flanged gate valve is transported, stainless steel valve and carbon steel valve will be separately packaged, because at room temperature, when carbon steel valve and stainless steel valve contact, will not immediately carburizing phenomenon, stainless steel valve has spots of corrosion is a certain period will appear.In the humid environment, if the carbon valve and stainless steel valve stacked together is easy to produce chemical reactions, thus damaging the protective layer of stainless steel valve, resulting in stainless steel valve rust;

3. After nearly 30 years of gate valve design, ZECO 6 inch gate valve products have stable performance and light switching torque;

4. ZECO 6 inch gate valve is all its own precision casting molds, and the casting sand is fine sand, beautiful appearance and clear casting characters.

Globe Valve A105 Material:

Description of 3 Inch Butterfly Valve:

ZECO 3 inch butterfly valve is a small diameter butterfly valve, usually manually operated, and the connection is usually lug type or wafer type, because the advantage of small diameter butterfly valve is that it is simple in accordance with the way, compared with other valve flange connection operation is fast and simple. ZECO as a professional on the wafer and lug type butterfly valve manufacturer, is strict to the material and appearance of the casting, casting usually arrive ZECO factory, will be isolated in the corresponding area waiting for QC inspector inspection, inspector will, in turn, the chemical composition, physical properties of the casting and design is individually and will follow the ERP system into the data of the product review file for later use. ZECO also pays great attention to every detail in the production process, and each process will be tested and recorded by corresponding inspectors in the ERP system.

Features of 3 Inch Butterfly Valve:

1. ZECO 3 inch butterfly valve can use metal seal structure and resilient seal structure, connection mode can also choose lug type, wafer type and flange connection, the choice of diversity, users can choose according to the actual working conditions to meet the requirements of working conditions;

2. ZECO 3 inch butterfly valve has low torque. Although it is small in size, ZECO engineers make every effort to design the product so that users can feel ZECO's improvement in design, rather than rush through it;

3. The stem of ZECO 3 inch butterfly valve is designed with anti blow-out structure, which can ensure the maintenance personnel to avoid personal safety damage caused by the pressure of the middle chamber pushing out the stem when replacing the packing;

4. The seat and sealing ring of ZECO butterfly valve can be replaced, which ensures the quick and convenient maintenance of maintenance personnel on site.

Description of 6 Inch Butterfly Valve:

ZECO provides detailed installation instructions to ensure high performance and long service life of the 6 inch butterfly valve. The capacity if piping flanges and valve depends the deformation of gaskets. Acting force of bolting is not only resists force to loosen the connection, but also to keep necessary compressing stress. Taking note of the force does not exceed the gasket load and pressure load. In order to ensure good connection, following instructions shall be noted.

(a) Check flange surface, if any defect appears leakage, groove or impress, repair before installation;

(b) The installation requests of Cast iron flange are more than the ductile cast iron. Proposed to use low-strength steel Bolted to reduce as a result of excessive pre-compression flange of the possibility of exceeding the prescribed stress. To fit flat flange gasket in the flat flange to prevent excessive torque of bolt flange damage. Should not be confused with convex planar flange of the loaded flange In the cast iron flange connection is particularly important that the top is installed on the better to ensure that in the absence of excessive load bolted gasket circumstances make an appropriate compaction force;

(c) Gasket have the capacity of resisting deformation and damage;

(d) Check the centration of assemble-part flanges, Lubricate the threads of boltings. Boltings shall be fasten sequential to make sure level contact between flange and gasket.

Features of 6 Inch Butterfly Valve:

1. One of the advantage of ZECO 6 inch butterfly valve is fast closure;

2. One of the advantage of ZECO 6 inch butterfly valve is disc sealing material is high grade rubber or Teflon, which successfully resist aging and abrasion;

3. One of the advantage of ZECO 6 inch butterfly valve is the bracket connected with the drive device conforms to ISO5211 standard;

4. One of the advantage of ZECO 6 inch butterfly valve is the stem is designed to meet API 609 requirements with a blowout resistant design.
