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.

   SERIES FEATURES

• The Patented MACSOLENOID® with its non-born
   out feature on AC series.

• Seven valve functions in one valve.

• Balanced spool unaffected by back pressure in
   the exhaust.

• A large checked accumulator which supplies the 
  pilot and air/spring return for consistent shifting.

• Use on lube or non-lube service.

• Various types of manual operators and solenoid
   enclosures.

• Optional low wattage DC solenoids down to 1W.

• A triple rated coil for 120/60, 110/50 or
   24VDC (6 Watt).

 

   OPERATIONAL BENEFITS

• Balanced spool, immune to variatons of
    pressure.

• Short stroke with high flow.

• Large spool area provides maximum
   shifting forces.

• Checked accumulator guarantees
   maximum pilot pressure.

• Powerful return force thanks to the
   combination of mechanical and air
   springs.

• Bonded spool with minimum friction,
    shifting in a glass-like finished bore.

• Wiping effect eliminates sticking.

• Pilot valve with balanced poppet, high
    flow, short and consistent response times.
