Types and Manufacturers of Industrial Valves Explained

Understanding Valve Kinds and Manufacturers

Valves are critical components in various industries, playing a vital role in controlling the flow of fluids, gases, and slurries. From municipal water systems to complex industrial processes, different types of valves serve diverse purposes. This article delves into the kinds of valves available in the market and highlights the key manufacturers leading the industry.

Types of Valves

1. Gate Valves These valves are primarily used for on/off control. They provide minimal flow resistance when fully open, making them suitable for high-pressure applications. Typically found in water and sewage systems, they are not ideal for throttling due to wear on the gate.

2. Globe Valves Globe valves are designed for regulating flow. Unlike gate valves, they provide better throttling capabilities, making them ideal for applications where flow control is critical. Commonly used in water, oil, and gas applications, their internal structure causes higher pressure drops compared to gate valves.

3. Ball Valves Known for their quick operation, ball valves feature a spherical disc that provides excellent sealing and is commonly used in gas and liquid applications. They are ideal for on/off control and can handle high-pressure and high-temperature conditions. This versatility has made them popular in both residential and industrial settings.

4. Check Valves These valves allow flow in one direction and prevent backflow, which can be critical in maintaining system integrity. They are used in various applications, including pumps, water supply, and drainage systems, to protect against potential damages from reverse flow.

5. Butterfly Valves Butterfly valves are notable for their compact design and lightweight construction. They use a rotating disc to control flow, making them suitable for large volume applications. They are commonly found in water distribution systems and chemical processing.

6. Pressure Relief Valves These valves are essential for safety, releasing excess pressure from equipment to prevent dangerous over-pressurization. They are widely used in boilers, pressure vessels, and other high-pressure systems.
