Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
The manual valve is a valve operated by the handle and the hand wheel, and is a commonly used valve on the equipment pipeline.
Valves are the most common equipment in chemical companies. It seems easy to install valves, but if they are not implemented in accordance with the re...

What is a Gate Valve?
A gate valve is a type of on-off valve that regulates fluid passage by raising or lowering a gate or wedge inside the valve body. Unlike throttling valves, gate valves are ideal for applications requiring a fully open or closed flow, ensuring minimal flow resistance when fully open and a complete seal when closed.
Gate valves play a vital role in numerous industrial applications, serving as essential devices for controlling the flow of liquids, gases, and steam.
Gate valves are suitable for both above-ground and underground installations. Especially for underground installations, selecting the correct valve type is crucial to avoid costly replacement expenses.
Applications of Gate Valves
Thanks to their excellent sealing properties and durability, gate valves are widely used in various scenarios requiring precise flow control, including:
Water Treatment Systems: For controlling and isolating water flow
Oil and Gas Pipelines: Essential for safe isolation in oil and gas transmission lines
Chemical Plants: Suitable for handling complex fluid environments across diverse media
Types of Gate Valves
Gate valves come in two main types based on structure and application needs:
1. Rising Stem Gate Valve: The stem rises along with the gate when the valve opens, providing a visual indicator of the valve’s position.
2. Non-Rising Stem Gate Valve: The stem remains stationary as the gate moves, making it ideal for spaces with height limitations.
Differences Between Soft-Sealing and Metal-Sealing Gate Valves
Gate valves are further categorized by their sealing materials into soft-sealing and metal-sealing types:
- Soft-Sealing Gate Valve: Uses materials like rubber or PTFE (polytetrafluoroethylene) for sealing, offering excellent tightness and corrosion resistance, ideal for medium- to low-temperature and clean media applications.
- Metal-Sealing Gate Valve:Features metal-to-metal sealing surfaces, providing high resistance to heat and wear, making it suitable for high-temperature, high-pressure, and abrasive media.
Choosing the right gate valve is critical to improving the efficiency and safety of your industrial system. Whether your industry requires a specific type of gate valve, RKSfluid can provide a tailored solution to meet your needs.
