External Seal Drain Cock DC-100: Metal-to-metal sealing technology improves the stability of the pipeline system

The External Seal Drain Cock DC-100 uses metal-to-metal sealing technology. Unlike traditional rubber seals or soft material seals, metal-to-metal sealing uses solid metal materials as the sealing contact surface, which has many unique advantages. Specifically, this design can provide a more durable and stable sealing performance, especially in low-pressure applications, which can effectively avoid leakage. The biggest feature of metal-to-metal sealing technology is its ultra-high durability. Metal materials themselves have strong wear resistance and are particularly suitable for pipeline systems that need to operate for a long time. Compared with traditional rubber seals, metal seals are not easy to wear, deform or age during long-term use, which ensures the service life of the valve and reduces the frequency of repairs and replacements caused by sealing problems. The sealing effect provided by metal-to-metal sealing is more stable. In low-pressure application environments, the sealing contact surface can provide good compression force to ensure a tighter seal and prevent leakage. This sealing method is extremely reliable, and the sealing performance will not decrease significantly even during long-term operation, which greatly improves the overall stability of the pipeline system.
The external seal drain cock DC-100 has an external and internal seat design, and different types of seats can be selected according to specific needs. The external seat design is mainly for the convenience of external pipe systems. When the drain valve is connected to the external pipe, the external seat can ensure the sealing of the joint and prevent leakage. The advantage of the external sealing design is its simple installation method, which can quickly and effectively connect to the external pipe. It is widely used in low-pressure drainage systems in industries, construction, agriculture and other fields. The internal seat design is an optimized solution for internal pipe systems. Compared with the external seat, the internal seat provides better sealing performance. In the internal pipe system, the sealing requirements of the valve are more stringent, especially in applications that require high leakproofness and sealing. The internal seat can effectively ensure that the water flow does not leak out, ensuring the stability and efficient operation of the drainage system. The external and internal seat design of DC-100 enables it to adapt to a variety of pipe installation requirements, and different pipe types and installation methods can be flexibly selected according to actual conditions. This design diversity not only improves the applicability of the product, but also simplifies the configuration of the pipe system and avoids complex operations during installation, thereby saving time and cost for users. This design concept can effectively meet the different needs of various industries, such as drainage systems in construction, chemical, power, agriculture and other industries, ensuring that both internal and external pipes can achieve excellent sealing, extend the service life of the equipment and reduce the need for later maintenance.
The external seal drain cock DC-100  is suitable for a variety of pipe materials such as copper, aluminum, steel and plastic, especially in low-pressure water pipes and liquid delivery systems. Copper pipes have good corrosion resistance and strength and are suitable for water supply systems. The use of the external seal drain cock DC-100  in copper pipe systems can ensure good sealing and will not leak under high temperature or high pressure conditions. Aluminum pipes are light and corrosion-resistant and are often used in pipe systems that need to reduce weight. DC-100 can adapt to aluminum pipes to provide durable drainage performance and avoid loosening or leakage problems due to long-term use. Steel pipes are widely used in industrial piping systems, especially in environments that are subjected to high-pressure fluids. The DC-100 drain valve can effectively cope with high-pressure environments through its metal-to-metal sealing technology, ensuring no leakage or instability when operating in steel pipe systems. Plastic pipes are usually used in lower pressure systems and have good corrosion resistance. DC-100 is suitable for various plastic pipes, such as PVC and PE pipes, and can work stably in these lightweight, corrosion-resistant piping systems, especially in cold water supply and drainage systems in residential and commercial buildings.
