integral bonnet needle valvesdual ferrule types
Integral bonnet needle valves with dual ferrule types represent a significant advancement in fluid control technology, combining robust construction with precision engineering. These valves feature a one-piece bonnet design that eliminates the traditional body-to-bonnet connection, significantly reducing potential leak paths and enhancing overall system integrity. The dual ferrule system consists of front and back ferrules that work in tandem to create a reliable, leak-tight seal through mechanical grip and surface contact. This design enables precise flow control in high-pressure and high-temperature applications, with pressure ratings typically reaching up to 6,000 psi and temperature capabilities of up to 450°C. The valve's stem is precision-machined to ensure smooth operation and features a fine thread design that allows for precise flow control. The packing system incorporates multiple layers of advanced materials, providing excellent sealing performance and extended service life. These valves find extensive applications in chemical processing, oil and gas, power generation, and research facilities where accurate flow control and system integrity are paramount.
