Bettis NG-Series Pneumatic Valve Actuator
The Bettis NG-Series is independently tested for LOCA (Loss of Cooling Accident), meets IEEE 382 standards, seismic, and various aging processes required for nuclear criteria.
Features
1.Independently tested to include LOCA (Loss of Cooling Accident), meets IEEE 382 standards, seismic, and various aging processes required to meet current nuclear qualification criteria.
2.Suitable for use in demanding applications requiring SIL environment
3.Patented Tension-Lok device positively locks the spring module to allow its safe removal and installation, eliminating accidental release of the spring force
4.PED 97/23/EC compliant to meet the stringent requirements of pressure mounting vessels
5.Meets both IP66 and IP67M specifications for submergence and high pressure water deluge test and offers superior water ingress and corrosion protection
6.Offers multiple configurations, with a modular design that enables safe field maintenance and reduced inventory costs
7.Interchangeable power and spring modules for quick reversal of the fail-safe mode
8.Suitable for use in demanding applications requiring SIL environment
9.Corrosion resistant, and internal and external surfaces are coated to protect in harsh environments
10.Offers a variety of mechanical and manual overrides for G-Series models
11.Adds an extra measure of versatility with its field serviceable modular configuration - it can be altered from a single acting to a double-acting and add a hydraulic manual override after installation
12.Offers complete valve operating system (VOS) for final valve control by combining the G-Series actuator, controls and a valve in a singular system
