How Do Control Valves Work?
Control Valves are engineered to provide precise control over fluid flow, making them indispensable in a variety of industrial settings. The key to their functionality lies in their unique design, particularly the control-shaped disc, which plays a crucial role in flow regulation.
Flow Control Mechanism At the heart of a control valve is the movable disc, positioned against a stationary ring seat within the valve body. When the valve is open, the disc is lifted away from the seat, allowing fluid to flow through the pipeline. The disc’s movement regulates the flow in several important ways:
Opens completely: The disc is fully lifted, allowing maximum flow.
Closes partially: The disc is partially lowered to reduce the flow rate.
Closes completely: The disc fully seals against the seat to stop the flow entirely.
This ability to finely adjust the flow is one of the primary control valve functions and makes them ideal for applications that require precise control.
Sealing Capabilities One of the notable advantages of Control Valves is their excellent sealing capability. The design enables the disc to create a tight seal against the flow, minimizing the risk of leaks. This makes Control Valves particularly effective in high-pressure environments, such as chemical processing or power generation, where maintaining a secure seal is critical to system performance and safety.
Directional Flow
Control valves are available in various configurations, including:
Two-way control valve design: Used to start, stop, or modulate fluid flow in one direction
Three-way control valve design: Enables fluid diversion between two different outputs or mixing two fluids into a single stream
These configurations expand the types of control valve applications, making them versatile tools in industries requiring varying flow solutions.
Superior accuracy with YLOK control valves Accuracy and precision YLOK control valves provide superior control performance and high reliability in a wide range of applications. They are designed to provide accuracy, precision and reliability in both general and more demanding service. They can be found in service in a wide range of customer industries, from oil & gas, chemical and petrochemical to power plants and pulp & paper mills.
Safety and sustainability All YLOK control valves are engineered, built and tested to be both safe and sustainable. They ensure the lowest possible emissions in accordance with ISO 15848 and in most cases certified fire safety according to API 607. Our control valves are also SIL 3 certified. Special cleaning options are also available for oxygen and cryogenic services for example.
