MAC 3 way solenoid valves small 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.

OPERATIONAL BENEFITS
1. The 4-way pilot develops maximum shifting  
    force both ways.
2. Patented conical seats for long life.
3. Short stroke with high flow.
4. Bonded poppet with minimal friction.
5. Wiping effect eliminates sticking.
6. Extremely repeatable response.
