Features of Stainless Steel Butterfly Valves and Lug-Type Butterfly Valves

Release date:

2019-06-25

  Butterfly valves are widely used in industrial pipeline control systems due to their ease of use. However, given the wide variety of butterfly valve types available, selecting the right one is crucial. Today, let’s explore the features of stainless steel butterfly valves and lug-type butterfly valves, as introduced by our editorial team from a butterfly valve manufacturer in Tianjin.   A stainless steel butterfly valve primarily consists of a valve body, stem, disc, and sealing ring. The valve body is cylindrical with a short axial length, housing a disc-shaped butterfly plate inside. Operation is achieved by rotating the disc—similar to a circular plate—through approximately 90° to open, close, or regulate the flow of the medium. When using a butterfly valve for flow control, it’s essential to choose the appropriate size and type carefully, ensuring precise regulation and preventing inaccuracies. Stainless steel butterfly valves can effectively manage the flow of various fluids, including air, water, steam, corrosive media, slurry, oils, molten metals, and even radioactive substances.   On the other hand, the disc of a lug-type butterfly valve is mounted perpendicular to the pipe’s diameter, primarily serving as a shut-off and throttling device within the pipeline. This type of valve features a disc-shaped butterfly plate that rotates around its own axis inside the valve body, enabling smooth opening, closing, or fine-tuning of the flow. Equipped with a worm gear reducer, the lug-type butterfly valve not only provides self-locking functionality, allowing the disc to remain securely fixed at any position, but also significantly enhances the valve’s operational performance. Beyond its compact design, lightweight construction, and minimal material usage, this valve boasts advantages such as small installation dimensions, reduced actuation torque, and effortless, rapid operation. Additionally, it delivers excellent flow control capabilities along with reliable sealing performance when fully closed. Finally, lug-type butterfly valves are installed between two pipe flanges using double-head bolts.

Stainless steel butterfly valves primarily consist of a valve body, stem, disc, and sealing ring. The valve body is cylindrical with a short axial length, housing the butterfly disc inside. These valves operate by rotating the disc—shaped like a circular plate—back and forth approximately 90° to open, close, or regulate the flow of the medium. When selecting a butterfly valve for flow control applications, it’s crucial to choose the right size and type to ensure accurate flow regulation and prevent inaccuracies. Stainless steel butterfly valves are suitable for controlling the flow of various fluids, including air, water, steam, corrosive media, slurry, oils, molten metals, and even radioactive substances.

 

The disc of the lug-type butterfly valve is mounted perpendicular to the pipe’s diameter, primarily serving as a shut-off and throttling device in the pipeline. The valve’s closing member—a circular disc-shaped butterfly—rotates around its own axis within the valve body, enabling it to open, close, or regulate flow. Equipped with a worm gear reducer, this type of butterfly valve not only provides self-locking capability, allowing the disc to remain securely in any desired position, but also significantly enhances the valve’s operational performance. This valve boasts a simple design, compact size, lightweight construction, reduced material usage, minimal installation footprint, low actuation torque, and effortless, rapid operation. Additionally, it offers excellent flow control capabilities along with reliable sealing when fully closed. Lug-type butterfly valves are installed by connecting them between two pipe flanges using double-head bolts.
