Lug Hard Sealed Butterfly Valve Product Introduction
Product Overview
The Lug Hard Sealed Butterfly Valve is designed for reliable performance in demanding applications. It features a hard-sealed design and lug-type connections. This valve provides robust sealing and versatile installation options. Its construction ensures excellent durability and minimal leakage, making it suitable for various industrial processes.
Design and Features
- Hard Sealed Design:
– Sealing Mechanism: The hard seal is achieved through a metal seat and disc. This design provides a tight seal, reducing leakage and ensuring reliable shutoff.
– Materials: It is typically made from high-strength alloys like stainless steel or other corrosion-resistant materials. The hard seal withstands high pressures and temperatures, offering enhanced durability and longevity.
- Lug-Type Connection:
– Design: The lug-type connection features threaded lugs on the valve body. These lugs allow the valve to be bolted directly to the pipeline flanges, facilitating easy installation and maintenance.
– Advantages: The lug design enables installation between flanges without needing a special gasket. It also allows for easy removal and replacement, as the valve can be serviced without disassembling the pipeline.
- Valve Body:
– Construction: The valve body is made from robust materials designed to handle high pressures and corrosive environments. This construction ensures long-term performance and reliability.
– Corrosion Resistance: The materials used in the valve body and hard seal offer excellent resistance to corrosive substances, ensuring a longer service life.
Design Standards
- Manufacturing Standards:
– ISO 9001: The valve is manufactured in accordance with ISO 9001 standards, ensuring consistent quality and reliability.
– API 609: It complies with API 609 standards for butterfly valves, defining performance criteria for various applications.
– ANSI/ASME B16.34: The valve meets ANSI/ASME B16.34 standards for pressure-temperature ratings, ensuring it can handle specified pressures and temperatures safely.
- Testing and Certification:
– Pressure Testing: Each valve undergoes rigorous pressure testing to ensure it meets performance standards and withstands operational pressures without leakage.
– Leakage Testing: The valve is tested for leakage to confirm the effectiveness of the hard seal and ensure no leakage under specified conditions.
- Installation and Maintenance:
– Installation: The lug design allows easy installation between pipeline flanges. The threaded lugs provide a secure connection without requiring special gaskets or additional hardware.
– Maintenance: The valve is designed for easy maintenance and replacement. The lug-type connection allows servicing without removing the entire pipeline, minimizing downtime and maintenance costs.
Summary
The Lug Hard Sealed Butterfly Valve combines a robust hard-sealing design with convenient lug-type connections. It offers excellent sealing performance, high durability, and ease of installation and maintenance. Manufactured to stringent standards, it is suitable for a wide range of industrial applications, ensuring reliable operation and long-term performance.
