Prism PI Valve Controller
Brand: ValmetThe 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 & 67).
- Screw-on cover enables convenient access without tools.
- Enclosure is made of high impact strength, corrosion-resistant polycarbonate.
- 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.
- NPT pneumatic connections are stainless steel reinforced for long life sealing under high torque stress conditions
- LED light bar brightly displays open, closed and solenoid status.
- Conduit entries available in NPT, metric threads or quick connectors.
