5.2 Air Signal Line Connections
The register contains a pneumatic circuits
to which air signal lines of copper tubing
are connected through their ports below the
register body.
- Air pressure:
0.20 to 0.69MPa
(adjusted to shutoff valve
specification.)
(Must be clean air)
- Air tubing diam.: Use
φ
6 ×
φ
4 copper tubing.
(Bite-type couplings
(Rc1/8) are provided.)
- Output air connections
OUT 1: Main valve (MV) open signal
OUT 2: Small valve (SV) close signal
IMPORTANT: At the supply air
connection, be sure to
provide a reducing valve
furnished with a filter
(Model 1301-8002).
