Absolute zero leakage to the local environment is provided by a completely welded construction throughout the pressure envelope.  O-ring and mechanical fed options are available.

This series is qualified to IEEE 344.  Seismic and stress analysis reports are available when required.

Valve operation is accomplished by energizing the solenoid.  The plunger moves directly to open the lower seat and shut off the upper seat.  A spring returns the plunger to its original position upon de-energization of the solenoid.  The valve can be designed for Normally Open, Normally Closed or Diverter operation as the application requires.

Extreme reliability is inherent due to rugged design, simplicity of operation and a minimum number of moving parts.  Isolation standoffs prevent excessive heat transfer to the solenoid operator.  Internal parts are contoured to retard buildup of contamination and sludge.  Compact, light weight design provides excellent resistance to seismic vibration and shock.  A completely enclosed and encapsulated coil ensures continuous operation during a LOCA event.
