Valve Positioners

A valve positioner is a critical device in industrial process control systems that ensures precise positioning of a valve by adjusting the air pressure applied to the actuator. This precise control enables the maintenance of a desired process variable, such as flow rate, pressure, or temperature, contributing to process stability and efficiency.

Applications

Valve positioners are widely used across various industries, including oil and gas, water treatment, chemical processing, and power generation. Typical applications include:

• Regulating the flow of liquids or gases in process pipelines
• Controlling line pressure within pipelines
• Enhancing process stability

Communication Options Include:

• 4–20 mA analogue outputs
• HART for advanced diagnostics and configuration
• Profibus PA, Profinet, and Foundation Fieldbus

Certifications and Approvals Include:

• ATEX approval
• SIL3 certification (Safety Integrity Level)

Additional Features

• Feedback Mechanisms
• Energy Efficiency
• Customisation
