Prism PI Diaphragm Valve Controller
Brand: Valmet
The Prism PI integrates an advanced position sensing system and integral pneumatic control for sanitary diaphragm and other linear applications.
Compact and durable, the PI is suited for corrosive, heavy washdown and hazardous areas.
Features- Suitable for high pressure washdown and temporary submersion, the PI is rated for NEMA 4, 4X and 6 (IP66 & IP67)
- Screw-on cover enables convenient access without tools
- Enclosure is made of high impact strength, corrosion resistant polycarbonate
- Prominent visual indicator boldly displays mechanical position status
- Low profile design minimizes height clearance required above actuator
- All electronics are sealed inside the linear C-module to protect against contamination, shock and vibration
- Intelligent high accuracy position sensor is solid state with no moving parts for long life. Sensor automatically adjusts dead band based on stroke length
