Valve Manufacturing Plant

Gate valves are commonly used to control the flow of fluids in pipelines, and their main function is to completely open or close the pipeline. There are various types of gate valves designed for different purposes. Below are the common types of gate valves:

1. Rising Stem Gate Valve

• Features: The stem moves up and down with the valve disk as the valve opens or closes, meaning the stem will rise or fall during operation.
• Application: Commonly used in large diameter pipelines and systems that require long-term operation. It is widely used in water treatment, oil, and gas industries.
• Advantages: Suitable for locations where remote monitoring of the valve’s status is required, as the rising stem makes it easy to observe the valve’s position.

2. Non-Rising Stem Gate Valve

• Features: Unlike the rising stem valve, the stem in a non-rising stem gate valve does not rise or fall during operation. Instead, the stem rotates to move the valve disk.
• Application: Ideal for places with limited space, particularly where compact installation is required.
• Advantages: Saves space and is suitable for high-density installations or underground pipelines.

3. V-Port Gate Valve

• Features: The valve disk has a V-shaped sealing surface, offering good flow regulation capability. It allows for precise control of flow between fully open and fully closed positions.
• Application: Mainly used in applications that require precise flow regulation, such as in chemical, petrochemical, metallurgy, and power industries.
• Advantages: Offers excellent flow control, making it ideal for situations that require precise flow adjustments.

4. Wedge Gate Valve

• Features: The valve disk is wedge-shaped. When the valve is closed, the disk tightly seals against the valve seat due to its wedge design, providing an effective seal.
• Application: Widely used in high-pressure, high-temperature, and various fluid pipeline systems.
• Advantages: Excellent sealing performance, suitable for large diameter pipelines.

5. Knife Gate Valve

• Features: The valve disk is shaped like a knife and is capable of cutting through and clearing solid particles in the flow, making it suitable for systems with solid or abrasive media.
• Application: Commonly used in fluid systems containing solid particles such as sewage, slurry, pulp, etc.
• Advantages: Capable of cutting and clearing solid impurities in the pipeline, suitable for corrosive or high-viscosity fluids.

6. Double Gate Valve

• Features: This valve consists of two valve disks, which provide better sealing and flow control capabilities.
• Application: Suitable for large diameter and high-pressure pipeline systems.
• Advantages: Strong sealing performance, ideal for high-pressure or special working conditions.

7. Hard-Seated Gate Valve

• Features: Uses metal-to-metal sealing, making it suitable for high-temperature and high-pressure environments. It offers strong sealing performance.
• Application: Primarily used in oil, gas, and metallurgy industries, especially in demanding working conditions.
• Advantages: Highly resistant to high temperatures and pressures, suitable for harsh working environments.

8. Soft-Seated Gate Valve

• Features: Uses soft materials like rubber, PTFE, etc., for sealing, making it suitable for standard working conditions.
• Application: Commonly used in water treatment, heating, and water supply systems.
• Advantages: Good sealing performance, ideal for lower temperature and standard operating environments.

9. Stainless Steel Gate Valve

• Features: The valve body and disk are made from stainless steel, providing excellent corrosion resistance.
• Application: Suitable for systems handling corrosive media or environments, such as chemical and seawater treatment industries.
• Advantages: Corrosion-resistant and heat-resistant, ideal for harsh environmental conditions.

10. Electric Gate Valve

• Features: The valve is operated by an electric actuator, allowing remote control of the valve’s operation.
• Application: Used in systems where automation is required, such as large plants, petrochemical, water supply, and heating systems.
• Advantages: Enables remote control and is suitable for places where manual operation is difficult.

These gate valves are designed with different features and applications to meet various requirements in terms of fluid media, pipeline size, and working conditions.
