จุดเด่นของ Airtec - Series SZ
- The valve operates after two input signals at 12 arriving within 0.5 s.
- The valve is actuated as long as the signals continue.
- If the input signals do not arrive within 0.5 s, the valve does not operate.
- Both signals must be reset before the valve switches back on.
จุดเด่นของ Airtec - Series SZS
- The valve operates after two input signals at 12 arriving within 0.5 s.
- The valve is actuated as long as the signals continue.
- If the input signals do not arrive within 0.5 s, the valve does not operate.
- Both signals must be reset before the valve switches back on.
- In addition, it has a self- locking device. A signal to 14 actuates the two-signal-control as a standard 5/2-valve.
- When the signal at 14 ends, the valve resets.
- This valve may be used either normally open or normally closed.
- Normally closed: pressure inlet port 1 (P).
- Normally open: pressure inlet port 3 (R).
- A signal arriving at 12 (Z) switches the flow of the valve from 1 (P) to 2 (A) and closes port 3 (R) after the set time has expired.
- Instead of supplying main pressure to either port 1 or 3, the branched signal line can be connected to 1 or 3.
- The signal line to port 1 or 3 must not be longer than the signal line to port 12.
