For plant acceptance the approval record counts as much as control quality. The 4WS2EM10-5X/45B11XHET315K31EV brings both together and controls 45 l/min nominal flow at 350 bar operating pressure under CCC-Ex conformity.
Benefits
- CCC-Ex with Ex TR type examination certificate as documented evidence for plant acceptance.
- 45 l/min nominal flow, 90 l/min maximum with direct actuation.
- 350 bar operating pressure in size 10, subplate mounting to ISO 4401-05-05-0-05.
- Internal pilot oil supply and return, so no extra control lines are required.
- 3.85 kg weight, FKM seals, HL hydraulic fluid, 24 VDC supply.
