FLOW CONTROL (AND CHECK) VALVES FG FCG -01/02/03/06/10 (1/8,1/4,3/8,3/4,1-1/4) PILOT OPERATED FLOW CONTROL (AND CHECK) VALVES FHG FHCG -02/03/06/10 (1/4,3/8,3/4,1-1/4) Sub-plate Mounting FLOW CONTROLS Hydraulic Fluids Fluid Types Any type of hydraulic fluids listed in the table below can be used. Petroleum base oils Synthetic fluids Water containing fluids Use fluids equivalent to ISO VG 32 or VG 46. Use phosphate ester or polyol ester fluid. When phosphate ester fluid is used, prefix "F-" to the model number because the special seals (fluororubber) are required to be used. Use water-glycol fluid. Note: For use with hydraulic fluids other than those listed above, please consult your Yuken representatives in advance. Recommended Viscosity and Oil Temperatures Viscosity ranging between 15 - 400 mm2/s (77 - 1800 SSU). Oil temperatures between -15/+70°C (5 - 158°F). Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above. Control of Contamination Due caution must be paid to maintaining control over contamination of the hydraulic fluids which may otherwise lead to breakdowns and shorten the life of the valves. Please maintain the degree of contamination within NAS 1638Grade 12. Use 25 μ m or finer line filter.
