1. The 4-way pilot develops maximum shifting

forces both ways.

2. Memory spring available.

3. Balanced spool, immune to variations of

pressure, also provides high flow.

4. Short stroke with high flow.

5. Bonded spool with minimum friction, shifting

in a glass-like finished bore.

6. Wiping effect eliminates sticking.

7. Long service life.
