77 Series

The MAC 77 Series valve is a 3-way balanced P.O.P. (Pilot Operated Poppet) valve pilot operated by a small direct operated 4-way solenoid valve - a one-off in air valve manufacturing. 

The 4-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

• Balanced poppet equals consistent high shifting
   forces.

• Valve shifting forces are consistent and
   independent of pressure fluctuations.

• High solenoid and return spring forces ensure
   high speed and precise repeatability.

• Built-in wear compensation - valve stroke is
   shorter than solenoid stroke.

• Constant high flow maintained throughout the
   pressure range.

• Exhaust contaminants are isolated from the
   solenoid.

• Full flow exhaust.

• Universal porting - 6 functions in one valve.

 

   OPERATIONAL BENEFITS

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

• Patented conical seats for long life.

• Short stroke with high flow.

• Bonded poppet with minimal friction.

• Wiping effect eliminates sticking.

• Extremely repeatable response.
