Valve assembly with dual actuation solenoids

A solenoid actuated valve assembly, comprising:

• a valve body having a main valve member slidably disposed in the valve body;
• a pilot valve body mechanically connected to and in fluid communication with the valve body, the pilot valve body having a pilot valve member slidably disposed in the pilot valve body;
• a first solenoid operated valve connected to the pilot valve body operable when energized to permit a pressurized fluid to move the pilot valve member from a pilot valve open to a pilot valve closed position;
• a second solenoid operated valve connected to the valve body operable when simultaneously energized with the first solenoid operated valve to allow the pressurized fluid to move the main valve member from a valve closed to a valve open position;
• and
• a third solenoid operated valve connected to the pilot valve body operable when energized and when both the first and second solenoid operated valves are de-energized to permit the pressurized fluid to move the pilot valve to the pilot valve closed position and the main valve member to the valve closed position.
