1. Balanced spool, immune to variations of
pressure.
2. Powerful return forces thanks to the
combination of mechanical and air springs.
3. Bonded spool with minimum friction, shifting
in a glass-like finished bore.
4. Wiping effect eliminates sticking.
5. Long service life.
Note: ISO series, valve and base are ordered separately, see page 239 for base code.
