1.Efficient E/P control logic:Utilizing the force-balance principle, it precisely converts 4-20mA signals into pneumatic outputs. High positioning resolution and linearity significantly improve the dynamic response and steady-state precision of pneumatic control valves.
2.Superior anti-vibration performance:The internal structure is optimized to maintain stability and reliability in complex industrial vibration environments, effectively preventing valve position drift caused by pipeline vibration.
3.Flexible span and zero adjustment:Equipped with an easy-to-use mechanism allowing for rapid field calibration of zero (4mA) and span (20mA). The wide adjustment range adapts to various linear or rotary actuators with different strokes.
4.Energy-efficient low air consumption:Optimized pilot valves and air circuits ensure extremely low air consumption in a steady state, significantly reducing the overall operational cost of the compressed air system.
5.Support for multiple mode conversion:Through simple internal component adjustments, direct (positive) or reverse action can be achieved. It also supports split-range control to meet complex process requirements.
6.Durable housing protection:The die-cast aluminum alloy casing features high-performance anti-corrosion coating. Excellent sealing protects against dust, moisture, and corrosive gases, meeting outdoor installation requirements.
7.Standardized mounting interface:Mounting brackets and feedback lever connectors comply with international standards, allowing for easy installation on various pneumatic diaphragm or piston actuators regardless of brand.
8.Easy maintenance and modular structure:The scientific layout of air modules and electronic units allows for inspection and cleaning of internal filters without disassembling the entire positioner, shortening maintenance time.
