Solenoid valves with external air port
Airtec solenoid valves
Airtec ME-series solenoid valves with external pilot port separate the control air circuit from the line pressure: the solenoid actuates a separate pilot air connection while the main flow passes through the main ports. This design is suitable for use in potentially explosive atmospheres and in applications where line pressure at the installation point is insufficient for direct self-piloting. The ME series covers 3/2-way and 5/2-way switching functions as well as impulse valves in port sizes G 1/8", G 1/4" and G 1/2".
| Type | Port | Function | Voltages |
|---|---|---|---|
| ME 05312HN | G 1/8" | 3/2-way | 12V DC, 24V DC, 24VAC, 115V, 230V |
| ME 07311HN / ME 07312HN | G 1/4" | 3/2-way NO/NC | 12V DC, 24V DC, 24VAC, 115V, 230V, 230X, 24X |
| ME 22311HN / ME 22312HN | G 1/2" | 3/2-way NO/NC | 12V DC, 24V DC, 24VAC, 115V, 230V |
| ME 22511HN | G 1/2" | 5/2-way | 24VAC, 115V |
| ME 22320HN / ME 22520HN | G 1/2" | 3/2-way / 5/2-way impulse | 12V DC, 24V DC, 24VAC, 115V, 230V |
Typical applications: Control valves in Zone 1 and Zone 2 per ATEX classification (painting, chemical and gas installations); applications with low line pressure at the installation point where direct-acting valves will not switch; control of hydraulic pilot valves with compressed air pilot; applications with long control lines between PLC cabinet and valve.
