TopWorx PD Series Smart Valve Positioner
Product Overview
The TopWorx PD Series Smart Valve Positioner, featuring the PD100 and PD200 models, redefines valve automation with user-friendly operation and advanced diagnostic capabilities. Engineered with non-contacting Hall-effect sensors, these positioners ensure wear-free performance and precise valve positioning for both linear and rotary actuators. The PD100 delivers reliable 4-20 mA control, while the PD200 enhances functionality with HART communication for real-time diagnostics and predictive maintenance. With a robust IP66/Type 4X enclosure and certifications for hazardous areas (ATEX, IECEx, cULus), the PD Series is a versatile choice for oil and gas, chemical, and wastewater applications, streamlining operations and reducing downtime.
Key Features
- Smart Diagnostics: PD200’s HART protocol enables real-time valve health monitoring and predictive maintenance.
- User-Friendly Interface: LCD display and push-button/magnetic key controls simplify setup and operation.
- Non-Contacting Sensors: Hall-effect technology ensures long-lasting, maintenance-free performance.
- Rapid Calibration: Auto-calibration via mechanical or magnetic buttons for quick commissioning.
- Energy Efficiency: Low air consumption (0.31 scfm at 60 psi) reduces operational costs.
- Broad Actuator Support: Compatible with linear (12–200 mm) and rotary (0–120°) actuators, single or double-acting.
- Hazardous Area Ready: Certified for ATEX, IECEx, and cULus (intrinsically safe for PD200).
- Durable Construction: IP66/Type 4X enclosure withstands harsh industrial environments.
- Configurable Alarms (PD200): Two PNP alarms for comprehensive valve status monitoring.
- Flexible Mounting: Compact design allows installation at any angle for space-constrained setups.
