Namur - 400 Series


The MAC 400 Series is a 5-way spool valve pilot operated by a small direct operated 5-way solenoid valve a one-off in air valve manufacturing.
The 5-way pilot means a low minimum operating pressure - no pistons - 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 or by inlet restrictions.

• 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.

 

 

OPERATIONAL BENEFITS

• The 4-way pilot develops maximum shifting   
   forces both ways.

• Memory spring available.

• Balanced spool, immune to variations of
   pressure, also provides high flow.

• Short stroke with high flow.

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

• Wiping effect eliminates sticking.

• Long service life.
