The LH Series Cross Scored Rupture Disc is a precision-engineered safety device designed for reliable overpressure protection in various industrial applications. The cross-scored design ensures that the disc opens along predetermined lines, providing controlled and accurate relief in the event of overpressure. This rupture disc is ideal for processes that require precise pressure control and protection against sudden pressure spikes.
The cross-scored pattern ensures that the disc opens in a controlled manner, reducing the risk of fragmentation and ensuring safe and predictable relief.
The precision scoring allows for highly accurate burst pressures, making it suitable for critical applications where precise pressure control is required.
Designed to open cleanly without producing fragments, protecting downstream equipment and maintaining process integrity.
Manufactured from various materials, including Stainless Steel, Nickel, Monel, and Inconel, to ensure compatibility with a wide range of media and operating environments.
Capable of operating at a high percentage of its burst pressure, minimizing the risk of premature failure and maximizing operational efficiency.
Available in a variety of sizes to accommodate different process requirements and equipment configurations.
