6 inch water valve is commonly used with flanged gate valves and various upper valves for water, including dirt separator.
Features of ZECO collector:
1. The release rate of primary gas of water through the exhaust valve assembly is 80%;
2. When the system runs for 4-6 hours, the gas content in the system can be reduced to less than half of the original level;
3. After a period of operation, the gas content in the system can be reduced to 0.4%;
4. Can separate the fouling at the same time during the exhaust;
5. After 50 cycles (flow rate of 0.5m/s), the dirt content decreased to less than 4%;
6. Suitable for systems with frozen liquid content up to 50%;
7. The minimum removal of air bubbles is 10 μm, while the minimum removal of impurity particles is 55μm.
8. The product complies with PED/DEP 97/23/EC(CE) standards;
9. The pressure loss is small and does not affect the flow rate.
6 inch Gate and butterfly valves are normally used in this dirt separator installation to ensure that water flow is blocked during maintenance to meet normal maintenance requirements. The dirt separator is applicable to heating, domestic hot water, geothermal utilization, central heating of thermal power plant, regional heating of boiler, ice storage air conditioning system ice storage and refrigeration and heat exchange & applicable to power industry, petrochemical industry, iron and steel metallurgy, paper, textile industry, food production, aerospace industry, shipping industry, automobile industry and civil heating (refrigeration) and other industries;It is used to protect equipment in the system that has low pressure or is sensitive to dirt because the heating device produces gas easily.

ZECO is one of the most professional control valve manufacturers china , and we have been devoted to produce control valve china for many years. If you want to know more details or want a quotation, just feel free to contact us!

Description of 6 Inch Ball Valve:

ZECO Valve Group is a well-known ball valve manufacturer in China. Since its establishment in 1991, it has been producing ball valves for nearly 30 years. In the production process, ZECO regards each valve as a handicraft to keep improving. With the support of high-tech production equipment and high-tech personnel, each product can achieve international quality. ZECO has been a high-tech enterprise in China for many years. Every year, ZECO devotes itself to the research and development of valves with more efficient performance and longer service life. The research and development cost of ZECO accounts for nearly 8% of the company's sales cost.

Features of 6 Inch Ball Valve:

1. ZECO 6 inch valve is designed with an auxiliary seat emergency seal system.Once the soft seal seat is damaged, emergency sealing can be performed by injecting the appropriate sealant into the auxiliary seal system.Emergency seals can also be used to flush and lubricate seat areas as necessary to keep seat areas clean without affecting sealing.The stem also has an emergency seal design for emergency sealant filling and flushing lubrication;

2. ZECO 6 inch valve with fire protection construction.The fire protection structure of the 6 inch ball valve is designed in accordance with API 607. In the event of a fire, the metal seat will be immediately in contact with the ball after the soft seal seat burned, to prevent the valve leakage caused by greater impact;

3. ZECO 6 inch valve body wall thickness will have a certain amount of design, carbon steel body, seat, bottom cover are in accordance with ASTM B733 surface chemical coating. In addition, if the user needs special customization, ZECO also has a variety of anti-corrosion materials for selection to meet the working conditions;

4. ZECO 6 inch valve in order to prevent the maintenance of the valve stem because of the excessive pressure in the cavity and the phenomenon of flying out, there is a design to prevent flying out of the stem.

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.

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.
