  • Difference Between PFA Lined Valves and PTFE(teflon) Lined Valves
    Difference Between PFA Lined Valves and PTFE(teflon) Lined Valves
    Jun 04, 2023
    PFA (Perfluoroalkoxy) lined ball valves and PTFE (Polytetrafluoroethylene) lined ball valves are both types of lined valves designed to handle corrosive and aggressive media. While they share similarities, there are key differences between the two in terms of material properties and performance characteristics.     Material Composition:   PFA Lined Ball Valves : PFA is a type of polymer that is similar to PTFE(teflon). It exhibits high chemical resistance and a broad temperature range. PFA lining is often used in ball valves to protect against corrosion and enhance the valve's performance in aggressive environments.   PTFE(teflon) Lined Ball Valves: PTFE is another fluoropolymer with excellent chemical resistance. PTFE lined ball valves use a lining made of PTFE to provide a barrier between the corrosive media and the valve's internal components.     Temperature Resistance:   PFA Lined Ball Valves: PFA generally has a higher continuous-use temperature compared to PTFE. This makes PFA lined ball valves suitable for applications involving elevated temperatures.   PTFE Lined Ball Valves : PTFE can withstand a broad range of temperatures but may have limitations in high-temperature applications compared to PFA.   Flexibility:   PFA Lined Ball Valves: PFA is known for its flexibility, allowing for easy lining of complex shapes. This flexibility can be advantageous in the manufacturing of valves with intricate designs.   PTFE Lined Ball Valves: PTFE is also flexible, but PFA may be preferred in applications where a high degree of flexibility is critical.     Chemical Resistance:   PFA Lined Ball Valves : Both PFA and PTFE exhibit excellent chemical resistance, but PFA may offer slightly better resistance to certain chemicals in specific applications.   PTFE Lined Ball Valves : PTFE is widely recognized for its exceptional chemical inertness, making it suitable for handling a broad range of corrosive substances.   Cost:   PFA Lined Ball Valves: PFA is generally considered a more expensive material compared to PTFE. Therefore, PFA lined ball valves may be more costly.   PTFE Lined Ball Valves: PTFE is a widely used and cost-effective material, making PTFE lined ball valves a more economical option in some cases.   In summary, while both PFA lined ball valves and PTFE lined ball valves are designed for corrosive applications, the choice between them depends on specific operating conditions, including temperature requirements, chemical exposure, and budget considerations. PFA lined ball valves may be preferred in high-temperature applications, while PTFE lined ball valves are known for their broad chemical resistance and cost-effectiveness.   If you need any of PFA PTFE PEP Teflon lined valves, please contat us now: info@geko-union.com!

  • How to Select ISO 12944 Coating Systems for Valves in different environment?
    How to Select ISO 12944 Coating Systems for Valves in different environment?
    Jun 04, 2023
    How do you correctly choose a coating system for your valves? With the extensive content of ISO 12944, how can you determine which environment your product falls into among C2, C2, C3, C4, C5, CX, lm1, lm2, lm3, lm4? Users mention that the coating's service life must reach 15 years—how do GEKO control valves prove this, and so on? To address these questions, GEKO control valves have summarized them into the ISO 12944 4S method for reference.   The 4S method is as follows: Step 1: Confirm the corrosion category (ISO 12944-2). Step 2: Confirm the durability of the protective coating (ISO 12944-1). Step 3: Select the coating system required for the project (ISO 12944-5). Step 4: Coating system laboratory validation (ISO 12944-6, optional).     Detailed description is as follows:   1) Confirming Corrosion Category (ISO 12944-2) The atmospheric environment is divided into six atmospheric corrosion categories: C1: Very low corrosion (Very low) C2: Low corrosion (Low) C3: Medium corrosion (Medium) C4: High corrosion (High) C5: Very high corrosion (Very High) CX: Extreme corrosion (Extreme)     Immersed in water or buried in the soil is divided into 4 categories: Im1: Freshwater Im2: Seawater or slightly brackish water without cathodic protection Im3: Soil Im4: Seawater or slightly brackish water with cathodic protection   2)Confirming the durability of protective valve coatings (ISO 12944-1) The standard specifies four different durability ranges: Low (L): Not exceeding 7 years Medium (M): 7-15 years High (H): 15-25 years Very high (VH): >25 years The durability of protective valve coatings is not a "guarantee period." The guarantee period is usually shorter than the durability, and there are no rules specifying the relationship between these two times. The "environmental type" and the "durability of the coating system" are the main parameters for selecting a coating system and must be given attention.     3)Selecting the Coating System Required for the valve Project (ISO 12944-5 or ISO 12944-9 in CX Environment) Based on the substrate, choose the minimum recommended coating system as per the standard. The coating systems in the standard are determined based on field application experience and laboratory performance test results according to ISO 12944-6. They provide valuable references. An example is the C2 table as shown below:     Points to Note:   1.The listed systems have been proven effective in practice, but it's not possible to list all coating categories. Other similar systems may also be feasible.   2.Under a given substrate type, coating performance can vary significantly depending on the specific composition of the coating. The substrate types described in Chapter 6 are just examples, and other types of valve coatings can also be used.   3.New technologies are constantly evolving and are often influenced by government regulations. Technologies proven effective through the following methods are acceptable:   a) After the application of these new technologies, tracking and recording verify their effectiveness.   b) Laboratory test results meet at least the requirements of ISO 12944-6 and ISO 12944-9.     4. Valve Coating System Laboratory Validation (ISO 12944-6) or Pre-Certification of Coating Systems (ISO 12944-9) In accordance with the standards, select a coating system. If the owner requires laboratory testing, the coating system must undergo laboratory testing, primarily based on ISO 12944-6 or ISO 12944-9. If your coating is a new technology, laboratory validation is necessary.   Step 1: Confirm the corrosion category (ISO 12944-2)   In this case, the valve project is located in a coastal industrial area, typically associated with energy, petroleum, and chemical industries. The environment is characterized by high humidity, high salinity, and high corrosion. Therefore, the selected environmental type based on the table is C5.     Step 2: Confirming the durability of protective valve coatings for project (ISO 12944-1)   The design service life is 20 years. According to the table, the selected range is 15 years to 25 years, so the durability choice is "High" (in practice, the durability of many valve coatings may also consider the construction cycle, typically assumed to be around 2 years).     Step 3: Select the coating system required for the valve project (ISO 12944-5)   The substrate of the sample is carbon steel, the environment is C5, and the durability is "High." Therefore, GEKO control valves choose to refer to Table B.1 and B.2 in Appendix C of ISO 12944-5, selecting coating systems for carbon steel under corrosion category C5. Specifically, ISO 12944-5/C5.03 or ISO 12944-5/C5.07 may be suitable.     Step 4: Coating System Laboratory Validation (ISO 12944-6, optional)   Conduct experimental tests to validate the selected coating system. This step may not be necessary if the user agrees to use the system recommended by the standard. However, if there is a desire to reduce potential disputes in the contract, testing confirmation can be performed before signing or periodic inspections can be conducted during the mid-project phase to ensure project quality.     According to ISO 12944-6, the testing items for C5-H are as follows:     After testing three panels, two of them meet the standard requirements, and it is deemed as compliant.   If you are looking for a reliable control valve ( Liquid, gas, powder) supplier for your project, please don’t hesitate to contact us: info@geko-union.com!

  • Regulating Valve(Control valve) Forms: Nine Categories of Regulating Valves (Control valves)
    Regulating Valve(Control valve) Forms: Nine Categories of Regulating Valves (Control valves)
    Jun 04, 2023
    Article Summary: Regulating Valves (Control valves) are classified into nine categories based on their structures: single-seat regulating valve, double-seat regulating valve, sleeve regulating valve, angle regulating valve, three-way regulating valve, diaphragm valve, butterfly valve, ball valve, and eccentric rotary valve. The first six are linear stroke, while the latter three are angular stroke. These nine are the most basic products, also known as common products, basic products, or standard products. Various special and custom products are developed based on these nine categories.     Below, the Instrumentation Engineering Network provides a brief introduction to the nine categories of Regulating Valves (Control valves):   Straight-through single-seat control valve: Widely used, with features of low leakage, small allowable pressure difference, complex flow path, and simple structure. Suitable for clean media occasions with strict leakage and low working pressure difference requirements. However, small-sized valves (nominal diameter DN < 20mm) can also be used in occasions with large pressure differences. Pay attention to checking the allowable pressure difference to prevent the valve from not closing tightly.   Straight-through double-seat control valve: In contrast to the straight-through single-seat control valve, it has the characteristics of large leakage and large allowable pressure difference. Therefore, it is suitable for clean media occasions with less strict leakage requirements and large working pressure differences. When selecting, pay attention to whether the valve's leakage meets the process control requirements.   Sleeve valve: The sleeve valve is divided into single-sealed and double-sealed structures. The former is similar to a single-seat valve and is suitable for single-seat valve occasions, while the latter is similar to a double-seat valve and is suitable for double-seat valve occasions. The sleeve valve has the advantages of good stability and easy disassembly and assembly, but it is 50%-200% more expensive than single-seat and double-seat valves, and it requires a special wrapped sealing gasket. The sleeve valve is widely used and is the second most widely used valve after single-seat and double-seat valves.   Angle valve: The throttling form is similar to a single-seat valve, but the valve body flow path is simple. Suitable for clean media occasions with low leakage and not large pressure differences, as well as occasions requiring right-angle piping.   Three-way valve: It has three passages and can replace two straight-through single-seat valves. Used for splitting and merging, as well as two-phase flow and occasions with a temperature difference not exceeding 150°C. When DN ≤ 80mm, the merging valve can be used for splitting occasions.   Diaphragm valve : Simple flow path, the diaphragm has certain corrosion resistance. Suitable for occasions with unclean media and weakly corrosive media where two-position shut-off is required.   Butterfly valve : It is equivalent to taking a straight pipe section as the valve body, and the valve body is equivalent to the valve seat. Therefore, it has good "self-cleaning" performance and is relatively lightweight. Suitable for unclean media and large-diameter, high-flow, and high-pressure difference occasions. When DN > 300mm, it is usually completed by a butterfly valve.   Ball valve : The "O"-shaped ball valve is an unobstructed valve when fully open, with the best "self-cleaning" performance. Suitable for occasions with particularly unclean media and fiber-containing media where two-position shut-off is required. The "V"-shaped ball valve has a nearly equal percentage control characteristic and is suitable for control occasions with unclean, fiber-containing media and a relatively large adjustable range.   Eccentric rotary valve : This valve is between a butterfly valve and a ball valve, with good "self-cleaning" and control performance, and can also be shut off. Therefore, it is suitable for adjusting occasions with unclean media and low leakage requirements."   GEKO Control Valve Manufacturer since 1956…
