MAC 56 Series Valve

• The patented MACSOLENOID® with its non-burn out feature on AC service.
• Seven valve functions in one valve.
• Balanced spool unaffected by back pressure in the exhaust or by inlet restrictions. May be plugged for 2-way operation.
• 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 1 watt.

• 3-Way Normally Open or Normally Closed (solenoid or remote air).
• 2-Way (by plugging a port) Normally Open or Normally Closed (solenoid or remote air).
• Internal pilot or External pilot for vacuum to 25 PSI main valve pressures on solenoid or remote air models.
• Manual and mechanical operators available.

1. Balanced spool, immune to variations of pressure.
2. Short stroke with high flow.
3. Large spool area provides maximum shifting forces.
4. Checked accumulator guarantees maximum pilot pressure.
5. Powerful return force thanks to the combination of mechanical and air springs.
6. Bonded spool with minimum friction, shifting in a glass-like finished bore.
7. Wiping effect eliminates sticking.
8. Pilot valve with balanced poppet, high flow, short and consistent response times.
