Name: Double eccentric butterfly valve Another name: High performance butterfly valve Applicable: Water plant, power plant, steel plant smelting, chemical industry Features: Longer life and good stability Features: Leflow is providing high quality Double-offset butterfly valve. We produce double eccentric butterfly valves with diameters ranging from DN100 to DN1200. Double offset uses two separate offsets to achieve a bubble-tight. One of the offsets is the location of the valve shaft relative to the centerline of the bore. Another offset is between the centerline of the disc/seat sealing surface and the shaft. This structure make the valve has following benefits: 1. Double Eccentric structure ensures low operating torques with zero leakage performance; 2. Inner and outer surfaces of the valve are coated with fusion bonded epoxy,and Its thickness can be adjustable; 3. Low moments are obtained by decreasing the friction through self-lubricating bushings; 4. Can bear high stretching stresses on the pipeline through the ductile iron body and disc; 5. High impact resistance. 6. Pressure loss is at minimum level by double shaft design. 7. Sealing gaskets fasten by bolt can be replaced at field condition; 8. With the o-rings on the bearing bushings, disc pin holes are protected against corrosion (Dry shaft); 9. Retaining ring is assembled to the disc with imbus bolts, the disc is protected against corrosion by placing o-rings under the bolts. 10. Stainless steel welding seat can reach better sealing

　　EC end cap seals are specialized sealing components commonly used in various industrial applications, designed to provide a secure seal at the ends of rotating shafts and cylindrical housings. They play a critical role in maintaining the integrity of mechanical systems by preventing the leakage of fluids and gases, while also protecting against the ingress of contaminants like dust and dirt. This article will explore the function, materials, applications, and advantages of EC end cap seals to offer a comprehensive understanding of their importance in modern machinery. 　　1. Function and Importance 　　The primary function of an EC end cap seal is to create a reliable seal between rotating shafts or fixed housings and their surrounding environment. By doing so, these seals ensure that vital fluids such as lubricants and coolants stay within the system while preventing external contaminants from entering and causing damage. Without proper sealing, machinery components can wear down faster due to friction and contamination, leading to operational inefficiencies and increased maintenance costs. Thus, EC end cap seals play an essential role in extending the lifespan and reliability of equipment. 　　2. Material Composition and Selection 　　EC end cap seals are typically made from materials that are highly resistant to wear, heat, and chemical exposure. Common materials used in the construction of these seals include nitrile rubber (NBR), fluorocarbon (FKM), silicone, and polytetrafluoroethylene (PTFE). Each material offers different advantages based on the operating conditions. For example, FKM seals are known for their resistance to high temperatures and harsh chemicals, while silicone seals excel in low-temperature environments where flexibility is crucial. The choice of material will depend on factors such as operating temperature, pressure, and exposure to chemicals or abrasive substances. 　　3. Applications of EC End Cap Seals 　　EC end cap seals are used in a wide range of industries, from automotive to aerospace, as well as in heavy machinery and manufacturing equipment. In the automotive sector, these seals are often found in transmission systems, wheel hubs, and gearboxes, where they help to maintain the efficiency of lubricants and prevent leaks. In industrial settings, EC end cap seals are crucial for machinery such as pumps, compressors, and motors, where they help protect sensitive components from environmental contaminants. Their ability to handle both dynamic and static sealing makes them versatile in many applications. 　　4. Advantages of EC End Cap Seals 　　The main advantage of EC end cap seals is their ability to provide long- lasting sealing performance under demanding conditions. These seals are designed to endure high levels of pressure and temperature while maintaining their integrity over time. They also offer excellent resistance to wear and chemical attack, making them ideal for applications in harsh environments. Additionally, their design allows for minimal friction during operation, which helps to reduce energy consumption and enhance the efficiency of the machinery. 　　Understanding the specific needs of a given application and selecting the right EC end cap seal can significantly improve the longevity and efficiency of industrial equipment, making them an indispensable component in modern mechanical systems.

　　Skeleton oil seals essential components in various mechanical applications, serve to contain lubricants and exclude contaminants from machinery. Their effectiveness is significantly influenced by the environment in which they are stored. Understanding the requirements for the storage environment of skeleton oil seals is crucial for ensuring their longevity, performance, and reliability. 　　1. Temperature Control 　　One of the primary considerations for storing skeleton oil seals is temperature. Extreme temperatures, whether hot or cold, can degrade the materials from which these seals are made. Ideally, they should be stored in a controlled environment where temperatures range between 15°C and 25°C. Higher temperatures can cause rubber components to harden and lose their elasticity, while low temperatures can make them brittle. Maintaining a stable temperature helps preserve their structural integrity. 　　2. Humidity Levels 　　Humidity also plays a vital role in the preservation of skeleton oil seals. Excessive humidity can lead to mold growth and degradation of the sealing material, while insufficient humidity can cause drying and cracking. The relative humidity of the storage area should be monitored and maintained between 30% and 50%. Using dehumidifiers or humidifiers, as required, can help stabilize these levels. 　　3. Protection from Contaminants 　　It is essential to protect skeleton oil seals from exposure to harmful chemicals and contaminants. They should be stored in a clean, dry environment away from strong solvents, oils, and other chemicals that could compromise their integrity. Ideally, seals should be wrapped in protective material and kept in sealed containers to prevent environmental damage. 　　4. Avoiding Physical Damage 　　Physical handling and storage of skeleton oil seals are critical to their preservation. They should be laid flat and not stacked directly on top of each other to avoid deformation. The use of racks or shelves that prevent excessive pressure and allow for easy access is recommended. Furthermore, it’s essential to handle them with clean, dry hands or gloves to prevent transfer of oils and dirt. 　　5. Periodic Inspection 　　Regularly inspecting the storage environment and the seals themselves ensures any potential issues can be addressed promptly. Noticing signs of swelling, discoloration, or cracks can help prevent the use of compromised seals, which could lead to equipment failure. Setting a schedule for inspection helps maintain both the seals and the overall storage conditions. 　　Adherence to these environmental requirements for skeleton oil seals not only extends their lifespan but also ensures optimal performance when installed in machinery. As industries continue to innovate and evolve, understanding the science behind material preservation will play an increasingly crucial role in achieving operational excellence. Thus, investing in appropriate storage solutions could be a key differentiator, impacting productivity and cost- effectiveness.
