*1. The spool in the neutral position is shown.
*2. Phosphate ester type fluids are also supported. When phosphate ester type fluids are used, prefix "F-" to the model
number because the special seals (fluororubber) are required to be used.

*1. Use the valves so that the relationship between the valve pressure difference and the flow rate, as specified in "Range
of flow control" on page 7, is met.
*2. This value is measured for each valve at a supply pressure of 14 MPa; it may differ depending on the actual circuit and
operating conditions.
