Nuclear & Power Division Air Pilot Solenoid Valves

Description

Valcor Nuclear Air Pilot Solenoid Valves are nuclear qualified valves with standard brass bodies and are available in a wide range of voltages and flow capacities. These valves are IEEE 323, 344 & 382 qualified for use inside containment.

Application

These air pilot solenoid valves are used as pilot operators for Air Operated Valves (AOVs) used in nuclear power plants. In a typical application, these air pilot valves feed and exhaust air pressure to the air actuator of the process valve (AOV) thus opening or closing the process valve.

Design Features and Benefits

  • Coil Insulation – Class H (min) Rated for 220°C (428°F)
  • Power Consumption – 220 watts (max.)
  • Continuous duty cycle without any cool down period
  • Valve ratings – ANSI class 150 to 2500.
  • Radiation resistance: Standard: 2×10*8 rads.
  • Qualified life: Up to 40 years + LOCA.
