Types of Stainless Steel Ball Valves
Two-Way Ball Valves
Two-way ball valves are the most common type, designed to control the flow of fluid in a single direction. They consist of a ball with a hole through the center, which aligns with the flow path when opened. Available in 304 or 316 stainless steel, these valves are suitable for a wide range of applications, including water, chemicals, and gases.
Three-Way Ball Valves
Three-way ball valves are designed for applications that require the diversion or mixing of flow. The valve’s configuration allows for three different flow paths, enabling operators to control the direction of fluid flow with precision. These valves are commonly used in HVAC systems and process control.
Multi-Port Ball Valves
Multi-port ball valves offer multiple flow paths, typically featuring four or more ports. They are ideal for applications where you need to control multiple flows or redirect fluids efficiently. These valves are commonly used in complex piping systems, such as those found in manufacturing and chemical processing.
High-Pressure Ball Valves
High-pressure ball valves are engineered to withstand extreme pressures, making them perfect for demanding environments such as oil and gas applications. Constructed from high-quality 316 stainless steel, these valves maintain performance and reliability even under significant stress.
Flanged Ball Valves
Flanged ball valves are equipped with flanges for easy installation in piping systems. They provide a secure and leak-proof connection, making them ideal for industrial settings. These valves are versatile and can handle various media types, including liquids and gases.
