APPLICATIONS
The high efficiency of Marotta’s 3-Way, 2-Position valves allows them to be used in a wide range of applications such as:
 

OPERATING DESCRIPTION
In the de-energized position, Port “A” is blocked by the poppet, which is held against the normally closed seat by the poppet return spring. Port “B” is directly open to Port “C”, permitting free flow in either direction (De-Energized Position).

With voltage applied, the solenoid armature assembly moves the poppet away from the normally closed seat and onto the normally open seat. Now, Port “A” and Port “C” are interconnected and Port “B” is sealed from Port “C” (Energized Position).

The valves are a balanced poppet design, requiring a relatively small solenoid actuator. This feature conserves power and minimizes the space required for installation.
