Series F2202/04.. - F2209/04..
The flanged valve of the 22 series in the control type direct and externally controlled requires compressed air between 4-8bar for switching.
The spring-loaded piston actuator is pressurised with compressed air and directly lifts the valve disc from the seat. The valve is closed by spring force.
The robust design has fast reaction times with high positioning forces of spring and control pressure.
