FAQs

A control valve regulates the flow of fluid by varying the size of the flow passage as directed by a signal from a controller. This adjustment impacts the rate of flow as well as the process quantities such as pressure, temperature, and fluid level.
The main types of control valves include globe control valves, which offer precise flow control; rotary control valves, known for their versatility and efficiency; and specialty control valves, designed for specific, often challenging applications.
The choice depends on several factors including the nature of the material to be controlled (liquid, gas, or steam), the required flow rate, the pressure drop across the valve, and the specific control characteristics needed. Consulting with a valve specialist is often recommended.
Globe control valves are characterized by a linear motion to throttle flow. They are highly effective for precise control in low to moderate flow rates and are favored for their ability to handle a wide range of operating temperatures and pressures.
Yes, certain rotary control valves are designed to handle slurry applications. Their design minimizes cavitation and erosion, making them suitable for liquids with suspended solids. However, the specific choice of valve depends on the slurry's characteristics.
Specialty control valves are engineered to address unique or challenging conditions not met by standard globe or rotary valves. This includes extreme pressures or temperatures, handling hazardous materials, or precise control demands.

Material selection is critical for ensuring compatibility with the fluid, resistance to corrosion or erosion, and suitability for the operating temperature and pressure. Incorrect material selection can lead to premature valve failure and operational issues.
