Product Description
CHX IP8081-03d / IP8181 Smart Electro-Pneumatic Valve Positioner | 4-20mA, Explosion-Proof
The IP8081/IP8181 intelligent electrical valve positioner is a microprocessor-based, two-wire field instrument designed for high-performance valve control. This advanced positioner effectively overcomes frictional and unbalanced forces on valve cores, significantly improving response speed and enabling rapid, accurate positioning.
Key capabilities include changing control types, setting split range control, configuring closed functions, adjusting valve stroke distance, modifying packing friction coefficients, setting valve types, and providing 4-20mA valve position feedback.
Key Features
- High positioning accuracy up to 0.5% F.S
- Easy operation with typically one-click setup completion
- Explosion-proof functionality for safe, reliable performance
- Automatic tuning and diagnostic capabilities
- Excellent vibration resistance
- No zero drift issues common with mechanical positioners
- Low power consumption for cost-effective operation
- Two-wire 4-20mA standard signal implementation
