For a direct-operated solenoid DCV, the solenoid __________ is placed in direct contact with the spool.

In a direct-operated solenoid directional control valve (DCV), the armature is the component that directly interacts with the spool to control fluid flow. When the solenoid is energized, an electromagnetic field is generated, which pulls the armature upwards or downwards, depending on the design of the valve. This movement of the armature is what shifts the spool to open or close the valve ports.

The armature's direct contact with the spool facilitates immediate response to the solenoid's activation, allowing for rapid switching of the flow direction or flow rate in the hydraulic circuit. This design is particularly useful in applications where quick and precise control is critical. Understanding the role of the armature in this context is essential for both installation and troubleshooting of solenoid-operated valves in electrical systems.

In contrast, other components such as the coil generates the magnetic field but does not physically engage with the spool. The spring typically serves to return the spool to its neutral position when the solenoid is deactivated, while the body houses the entire assembly but is not involved in the direct operation of the valve function.
