NACHI Valve Hidrolik DMA Manual (Katup Hidrolik)

1. The following are the three types of lever operations.
- Spring Offset Type (Type A)
The lever is normally kept in the end position by the spring. Raising
the lever performs switching, and the lever returns to its original position when released.
- Spring Center Type (Type C)
The spool is normally in the center of position 3. After switching to either end,
the spring returns the lever to its center position when the lever is released.
- Detent Type (Type F, Type E) A notch at spool position 3 or position 2 acts as a stop.
2. Pressure loss is the same as that for the SA-G01/ G03, so see SA-G01/G03 for more information.
3. The lever mounting orientation can be positioned at 90° increments by changing the orientation of the lever
side cover.
4. For PT connection type DMA-G01/G03-*7*-(J)20, closed cross DMA-G01/G03-*7X-(J)20 is the standard type.
5. The relationship between the lever switching positions and JIS symbols is shown below. (See the installation
dimension diagrams for symbols & 1
and & 2.)
6. Mounting bolts are not included with the 01 size.
