ARP20/30/40, Direct Operated Precision Regulator
The ARP is a modular style, direct operated precision regulator. A locking adjustment knob allows the pressure to be set, and then locked to prevent accidental setting changes. The ARP20/30/40 series is available with a back flow function that exhausts the air pressure in the outlet side reliably and quickly. Special applications include (10-) clean room compliant, (20-)copper-free, fluorine-free, and (21-) clean room compliant, copper-free, fluorine-free and silicon-free.
- Direct operated precision regulator
- Sensitivity: within 0.2%F.S.
- 3 types of set pressure allow more freedom in designing a circuit
- Repeatability: within ±1%F.S.
- Backflow function available

Example 2)
When the air supply is cut off and
releasing the inlet pressure to the
atmosphere, the residual pressure
release of the outlet side can be
ensured for a safety purpose.
Example 1)
When the pressure in the rear and
the front of the cylinder differs:
• With the backflow function it incorporates a mechanism to exhaust the air pressure in
the outlet side reliably and quickly.
How to Order

Note 1) Options B, G, H are shipped together, (but not assembled).
Note 2) Set nut is included for bracket.
Note 3) 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 lead wire entry.
(Select “wiring bottom entry” when the semi-standard Y is chosen simultane-
ously.)
Note 4) The only difference from the standard specifications is the pressure regulator
spring.
It does not restrict the setting of 0.2 MPa/0.6 MPa or more.
When the pressure gauge is attached, a 0.2 MPa pressure gauge for 0.2 MPa
setting will be fitted, and a 0.7 MPa pressure gauge for 0.6 MPa setting will be
fitted.
When a digital pressure switch is attached, the pressure display is fixed to 1.0
MPa.
Note 5) For thread type: NPT. This product is for overseas use only according to the
new Measurement Law. (The SI unit type is provided for use in Japan.) The
digital pressure switch will be equipped with the unit conversion function, set-
ting to psi initially.
Note 6) For options: E1, E2, E3, E4. This product is for overseas use only according
to the new Measurement Law. (The SI unit is provided for use in Japan.)
