Note 1) Pressure gauge connection threads are not available for F.R.L. unit with a square embedded type pressure gauge or with a digital pressure switch.
Note 2) –5 to 50°C for the products with the digital pressure switch
Standard Specifi cations
Note 1) Set the inlet pressure to at least 0.05 MPa higher than the set pressure.
Note 2) Option B, G, H, M are not assembled and supplied loose at the time of
shipment.
Note 3) Assembly of a bracket and set nuts (applicable to the AR20(K)-B to
AR40(K)-B). Including 2 mounting screws for the AR50(K)-B and AR60(K)-B
Note 4) When the pressure gauge is attached, a 1.0 MPa pressure gauge will be fi tted
for standard (0.85 MPa) type. 0.4 MPa pressure gauge for 0.2 MPa type.
Note 5) When choosing with H (panel mount), the installation space for lead wires will
not be secured. In this case, select “wiring top entry” for the electrical entry.
(Select “wiring bottom entry” when the semi-standard Y is chosen
simultaneously.)
Note 6) Pressure can be set higher than the specifi cation pressure in some cases, but
use pressure within the specifi cation range.
Note 7) For pipe thread type: NPT.
Cannot be used with M: Round pressure gauge (with colour zone). Available
by request for special.
The digital pressure switch will be equipped with the unit conversion function,
setting to psi initially.
Note 8) For options: E1, E2, E3, E4.
Note 9) 앪: For pipe thread type: NPT only
Note 10) 왕: Select with options: E1, E2, E3, E4.
