Product Description

Product Description

In the complex and dynamic world of industrial process control, the accurate positioning of control valves is not just a matter of efficiency but also of safety, product quality, and overall plant performance. The 582i Electro - Pneumatic Valve Positioner emerges as a pivotal component in this domain, designed to bridge the gap between electrical control signals and pneumatic valve actuation with remarkable precision and reliability.

 

 

Modular Design

The 582i is engineered with a compact form factor, which is a significant advantage in industrial settings where space is often at a premium. Its small footprint allows for easy integration into existing valve assemblies, whether in new installations or as part of a retrofit project. This lightweight design also reduces the stress on the valve mounting brackets and associated structures, contributing to the overall stability of the valve - positioner system.

Physical Design

The 582i features a compact and robust design, which is a key advantage in industrial environments where space is often limited. Measuring [specific dimensions], it can be easily integrated into existing valve setups without requiring significant modifications. The unit weighs approximately, ensuring that it can be handled and installed with relative ease.

 

Working Principle

The operation of the 582i is based on a sophisticated process that converts electrical signals into pneumatic signals to control the position of the valve stem. When the unit receives an electrical input signal (4 - 20 mA DC), it is processed by an internal circuit. This circuit contains a torque motor, which generates a mechanical force proportional to the magnitude of the input current.
