1. Introduction to LT Butterfly Valves


Butterfly valves are essential components in industrial equipment, particularly in flow control systems. The LT butterfly valves, short for "Low Temperature," are designed to operate efficiently in extreme temperature conditions. They provide reliable shut-off and regulation capabilities, making them an integral part of various industries.

2. Resilient-Seated Butterfly Valves


Resilient-seated butterfly valves offer excellent sealing capabilities, making them suitable for low-pressure applications. These valves feature a flexible rubber seat that seals tightly against the disc, preventing leakage. Industries such as water treatment, HVAC, and food and beverage often utilize resilient-seated butterfly valves for their cost-effectiveness and ease of maintenance.

3. High-Performance Butterfly Valves


High-performance butterfly valves are engineered to withstand higher pressure and temperature conditions compared to resilient-seated valves. They are constructed with sturdier materials and often come with a metal seat, providing enhanced durability and tight shut-off capabilities. These valves find applications in demanding industries such as oil and gas, chemical, and power generation.

4. Double Offset Butterfly Valves


Double offset butterfly valves feature a unique disc design that ensures a tight seal with minimal friction. The offset disc minimizes wear and tear on the seat, resulting in improved valve performance and longevity. These valves are suitable for applications involving high temperatures, high pressures, and abrasive media. Industries such as mining, pulp and paper, and refining benefit from the reliability and efficiency of double offset butterfly valves.

5. Triple Offset Butterfly Valves


Triple offset butterfly valves, also known as eccentric disc valves, provide excellent sealing capabilities even in high-pressure and high-temperature environments. The unique triple offset design ensures a bubble-tight shut-off, reducing leakage risks. These valves are widely used in industries such as petrochemicals, oil and gas, and pharmaceuticals, where precise control and tight shut-off are critical.

6. Wafer Butterfly Valves


Wafer butterfly valves are compact and lightweight, making them ideal for space-constrained applications. These valves are designed to fit between two pipeline flanges, eliminating the need for additional flanges or brackets. With their simplicity, cost-effectiveness, and ease of installation, wafer butterfly valves are commonly utilized in HVAC systems, irrigation, and low-pressure applications.

7. Lug Butterfly Valves


Lug butterfly valves feature threaded inserts on both sides of the valve's body, allowing them to be installed without using additional flanges. These valves offer versatility as they can be installed in both dead-end and bi-directional flow applications. Industries such as water distribution, wastewater treatment, and marine rely on lug butterfly valves for their flexibility and ease of maintenance.

8. Flanged Butterfly Valves


Flanged butterfly valves are designed with flanges on each end, enabling direct installation between pipeline sections. These valves provide a sturdy and leak-free connection, making them suitable for applications with high-pressure requirements. Industries such as oil and gas, chemical processing, and water treatment utilize flanged butterfly valves for their robust construction and reliable performance.

9. Eccentric Butterfly Valves


Eccentric butterfly valves offer improved flow control capabilities due to the off-centered disc design. These valves are suitable for applications that require precise throttling or regulating of flow. The eccentric disc design reduces friction and wear, resulting in enhanced valve performance and extended service life. Industries such as power plants, HVAC systems, and water treatment plants benefit from the versatility and precision of eccentric butterfly valves.
