Understanding Double Flanged Butterfly Valves
А двухфланцевый дроссельный клапан is a versatile valve designed for regulating or isolating the flow of fluids in a piping system. It consists of a disc or plate that rotates on a central axis to control the flow, offering a tight shut-off when closed. Here are some key features and advantages of TWT’s double flanged butterfly valve:
Прочная конструкция: TWT’s double flanged butterfly valve is constructed using high-quality materials, ensuring durability and long-lasting performance. The valve is designed to withstand high pressure and temperature conditions, making it suitable for a variety of applications.
Double Flange Design: The double flanged design of the valve allows for easy installation between flanges in the pipeline. The flanges provide a secure and leak-free connection, ensuring the integrity of the system.
Bi-Directional Flow: Double flanged butterfly valves are designed to allow flow in both directions, making them suitable for applications where the flow direction may vary.
Эффективное управление потоком: The streamlined disc design of the double flanged butterfly valve ensures minimal flow restriction and pressure drop, resulting in efficient flow control and reduced energy consumption.
Understanding Lug Type Butterfly Valves
A lug type butterfly valve, like the double flanged butterfly valve, is used for regulating or isolating fluid flow. It features threaded inserts or lugs on each side of the valve body, allowing for easy installation and removal from the pipeline. Here are some key features and advantages of TWT’s lug type butterfly valve:
Versatile Installation: Lug type butterfly valves are designed for easy installation and removal in a pipeline. The valve can be installed using bolts and nuts on each lug, making it suitable for applications where frequent maintenance or replacement is required.
Bi-Directional Flow: Similar to the double flanged butterfly valve, the lug type butterfly valve allows flow in both directions, offering versatility in fluid control applications.
Secure Sealing: The lugs on the valve body provide secure sealing between the valve and the pipeline, ensuring leak-free operation and system integrity.
Cost-Effective Solution: Lug type butterfly valves are often more cost-effective compared to double flanged butterfly valves, making them a preferred choice for applications where budget constraints are a consideration.

Double Flanged Butterfly Valve vs. Дроссельный клапан с выступом
While both double flanged butterfly valves and lug type butterfly valves serve similar purposes, they differ in their design and installation methods. Here are the key distinctions between the two:
Installation: Double flanged butterfly valves are installed between flanges in the pipeline, using bolts and nuts to secure the valve. С другой стороны, lug type butterfly valves have lugs or threaded inserts on each side of the valve body, allowing for easy installation and removal using bolts and nuts.
Обслуживание: Lug type butterfly valves offer the advantage of easy removal for maintenance or replacement, thanks to their lug design. Double flanged butterfly valves, while still serviceable, require the removal of the valve from the pipeline between the flanges.
Cost: Lug type butterfly valves are often more cost-effective compared to double flanged butterfly valves, making them a preferred choice for applications where budget constraints are a consideration.
