MAC 3 way solenoid valves large 68 Series

The MAC 68 Series is a 3-way balanced spool valve pilot operated by a small direct operated 4-way solenoid valve - a one-off in valve manufacturing.  The 4-way pilot means a low minimum operating pressure - no pistons or springs - and minimal resistance to shifting.  The balanced design in the pilot means shifting forces are consistently high and response times are repeatable regardless of inlet pressure fluctuations.

OPERATIONAL BENEFITS
1. The 4-waypilot developsmaximum shiftingforces bothways.
2. Balancedspool, immune to variations of pressure, alsoprovides
highflow.
3. Bondedspool withminimum friction, shiftingin a glass like

4. Pilot withbalancedpopet, highflow, short and consistent
responsetimes.
