Bettis NG-Series Pneumatic Valve Actuator
Rp123000.00
The Bettis NG-Series Pneumatic Valve Actuator is engineered to meet the rigorous demands of critical nuclear applications. It has been independently tested for Loss of Cooling Accident (LOCA) scenarios and complies with IEEE 382 standards, seismic qualifications, and nuclear aging criteria. Designed for reliability and safety, the NG-Series actuator provides exceptional performance in harsh and demanding environments, with versatile configurations and superior corrosion resistance.
Key Features
Nuclear Compliance: Tested for LOCA scenarios, meeting IEEE 382 standards, seismic qualifications, and nuclear aging criteria.
SIL-Capable: Suitable for Safety Integrity Level (SIL) environments.
Tension-Lok Technology: Patented device for safe spring module removal and installation, preventing accidental spring force release.
Robust Construction: Compliant with PED 97/23/EC for pressure vessels and certified to IP66 and IP67M for submergence and high-pressure water protection.
Modular Design: Enables field serviceability, reduces inventory costs, and allows quick fail-safe mode reversal.
Flexible Actuation: Supports single-acting, double-acting, and hydraulic manual override configurations, even post-installation.
Versatile Applications: Compatible with ball, butterfly, plug valves, louvers, dampers, and other quarter-turn devices.
Enhanced Durability: Corrosion-resistant internal and external coatings for extended service life in harsh conditions.
Comprehensive System: Can be combined with a valve and controls for a complete Valve Operating System (VOS).
