Airtec pneumatically actuated valves
Valves
Pneumatically actuated valves from Airtec are switched by a compressed air control signal without requiring electrical power. The Airtec programme covers 3/2-way and 5/2-way designs (NC, NO, impulse) for port sizes M 5 to G 1/2" in Standard (B) and Precision series, plus ATEX-approved variants (-X) for use in potentially explosive atmospheres. Time delay valves VZ with adjustable delay times (0.25-300 s) and two-hand safety blocks SZ/SZS for safety-related applications are also part of the range.
| Type | Port | Function | Variants |
|---|---|---|---|
| Airtec L 25 | M 5 | 3/2-way, 5/2-way (impulse, spring) | Standard, ATEX-X, air spring |
| Airtec L 28 | G 1/8" | 3/2-way, 5/2-way (impulse, spring) | Standard, ATEX-X |
| Airtec P 05 | G 1/8" | 3/2-way air spring (NC) | ATEX-X |
| Airtec P 07 | G 1/4" | 3/2-way and 5/3-way (exhausted) | Standard, ATEX-X |
| Airtec P 12 | G 1/2" | 3/2-way, 5/2-way (impulse, spring) | Standard, ATEX-X, dominant |
| VZ 25 / VZ 18 | M 5 / G 1/8" | Time delay valve 3/2-way | 0.25-300 s adjustable |
| SZ / SZS 14 510 | G 1/4" | Two-hand safety block | Precision, self-holding port |
Typical applications: Pure compressed air controls without electrical power in potentially explosive atmospheres (ATEX Ex Zone 1/2, 21/22), pneumatic cascade controls in process engineering, two-hand safety circuits on presses and punch presses (SZ/SZS), time-delayed sequence controls (VZ), and applications where no power supply is available.
