High-Cycle Valve Stem Packing
Product Name: High-Cycle Valve Stem Packing
Construction:
End Rings: Two High-density Inconel-reinforced Flexible Graphite Rings.
Center Rings: Three Die-molded graphite Rings.
Dimensions: Customized
Pressure: Up to 10,000 psi.
Temperature Range:
Up to 1200°F (650°C) across full PH range.
Up to 850°F (455°C) in steam or atmospheric service.
The high-cycle valve stem packing is engineered to provide reliable, long-lasting sealing under extreme pressure and temperature conditions. Its design efficiently converts axial load into radial sealing force, ensuring minimal stem drag while maintaining positive sealing.
Key Advantages
Positive stem sealing even under extreme loads.
Reduced stem friction for smooth valve operation.
Durable in high-cycle applications, ensuring long-term reliability.
Adaptable to both standard and custom valve configurations.
Applications
Designed for rising stem and rotating-rising stem valves.
Compatible with standard and metric stuffing boxes.
Suitable for high-pressure and high-temperature environments, including steam and atmospheric conditions.
