Product Description
Two-position four-way and three-position four-way proportional directional valves are used as direct-acting devices in valve plate design.
They are operated by means of proportional solenoids with centering threads and removable coils.
The coil is controlled by external control electronics.
Setup:
The basic components of the valve include:
Housing with connecting surfaces
control spool with compression spring
Coil with centering thread
Function:
When the coil is de-energized, the compression spring keeps the control spool in the center position -
Direct operation of the control spool by energizing a proportional solenoid, e.g. control coil "b".
Moves the control spool to the left in proportion to the electrical input signal.
Connection from P to A and from B to T by means of a throttling cross-section with progressive fluid characteristics
Closing coil
The control spool is returned to the center position by the compression spring.
