3. High-Pressure Ball Valve Features
KNKE high-pressure ball valves are designed with cutting-edge technology to ensure maximum efficiency, reliability, and safety. Here are the main features:
Forged Components
All parts of the valve are forged, offering superior strength, wear resistance, and long-lasting durability. Forged materials are resistant to high pressure and prevent mechanical failures.
Bottom-Mounted Stem with Double Sealing Structure
The valve features a bottom-mounted stem and double sealing structure, which ensures excellent sealing performance, even under high-pressure conditions. This design minimizes the risk of leakage and guarantees long-term functionality.
Inlaid Seat with O-Ring for Enhanced Sealing
An inlaid seat with an O-ring provides added protection against media leakage, ensuring the valve maintains a secure seal throughout its service life. This design is critical for high-pressure and high-temperature applications.
Self-Lubricating Sealing Surface
The sealing surface is made of Nylon 1010, which has a low friction coefficient (one-third that of beryllium bronze). This self-lubricating material reduces wear and tear and is resistant to bending and impact, ensuring the valve operates smoothly for an extended period.
High-Temperature Resistance with STL Alloy
The sealing surface is enhanced with STL alloy, which provides exceptional wear resistance and can withstand high temperatures. This makes it suitable for demanding environments where other materials might fail.
Fire and Static Safety Design
The valve includes fire-resistant and static electricity protection features, further increasing the overall safety during operation. These additional design elements are essential for preventing hazardous situations in critical systems.
