2-Way Solenoid Controlled, Normally Closed (N.C.)
Principle of Operation
Closed Position
The restriction continuously allows line pressure
into the control chamber. The solenoid controls outflow
from the control chamber. When the solenoid is
closed it causes pressure to accumulate in the control
chamber, therefor forcing the valve to close.
Open Position
the Solenoid releases more flow from the
control chamber than the restriction can allow in.
This causes the accumulated pressure in the control
chamber to drop, enabling the line pressure acting on
the plug to the valve.
3-Way Solenoid Controlled, Normally Open (N.O.)
Open Position
The de-energized solenoid blocks the valve internal
line pressure inlet and opens the drain port, venting
the control chamber to the atmosphere, therefor fully
opening the valve.
Closed Position
Energizing the solenoid opens the internal line pressure
inlet and blocks the drain port. This pressurizes the
control chamber, closing the valve.
