Hydraulic Filter Assembly

The valve is supplied with an integrated, high-capacity filter. The broad range filter protects the internal

hydraulic control components from large oil-borne contaminants that might cause the hydraulic

components to stick or operate erratically. The filter is supplied with a visual indicator which shows when

the recommended pressure differential has been exceeded and thus replacement of the element is

necessary.

LVDT Position Feedback Sensors

The SonicFlo control valves use a dual-coil, dual-rod LVDT for position feedback. The LVDT is factory set

to give 0.7 Vrms feedback at minimum position and 3.5 Vrms feedback at maximum position, when

supplied with 7 Vrms excitation at 3000 Hz.
