Features

  • 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.
  • Suitable for use in demanding applications requiring SIL environment
  • Patented Tension-Lok device positively locks the spring module to allow its safe removal and installation, eliminating accidental release of the spring force
  • PED 97/23/EC compliant to meet the stringent requirements of pressure mounting vessels
  • Meets both IP66 and IP67M specifications for submergence and high pressure water deluge test and offers superior water ingress and corrosion protection
  • Offers multiple configurations, with a modular design that enables safe field maintenance and reduced inventory costs
  • Interchangeable power and spring modules for quick reversal of the fail-safe mode
  • Suitable for use in demanding applications requiring SIL environment
  • Corrosion resistant, and internal and external surfaces are coated to protect in harsh environments
  • Offers a variety of mechanical and manual overrides for G-Series models
  • 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
  • Offers complete valve operating system (VOS) for final valve control by combining the G-Series actuator, controls and a valve in a singular system
