This is the filter from a single stage Dungs valve running @ 143kw...... the black stuff is sticky and smells like flux......... suprisingly it was choking the valve so much that the internal working pressure (measured from the test point on the valve body), was 8mb at full fire......... unsuprisingly it locked out often!
