Direct-Operated Precision Regulator, Modular Type (With Backflow Function), ARP20(K) To ARP40(K) Series Specification

Model Number Notation

Model number example

• *Note 1) Options B, G and H are not assembled and are supplied loose at the time of shipment.
• *Note 2) Set nuts are included with the 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 electrical entry. (Select “wiring bottom entry” when the semi-standard Y is chosen simultaneously.)
• *Note 4) The pressure regulator spring is the only difference from the standard specification. Does not restrict setting to a pressure of 0.2 MPa / 0.6 MPa or higher. Moreover, if a pressure gauge is attached, a 0.2‑MPa-use pressure gauge for 0.2‑MPa settings will be fitted or a 0.7‑MPa‑use pressure gauge for 0.6 MPa settings. For all times when a digital pressure switch is attached, the pressure display is fixed to 1.0 MPa.
• *Note 5) Thread type: NPT is applicable. Under new Japanese measurement laws, this product is only available for sale outside of Japan (SI units are used in Japan). The digital pressure switch, which has the unit selection function, has a default setting of psi.
• *Note 6) Options: E1, E2, E3, E4. Under new Japanese measurement laws, this product is only available for sale outside of Japan (SI units are used in Japan).
• *Note 7) ○ is for thread type NPT only.
• *Note 8) △: Combination available for options E1, E2, E3, E4.

Specifications

• *Note 1) When a product with the backflow function (ARP20K to 40K) is chosen, set the inlet pressure to at least 0.05‑MPa higher than the set pressure.
• *Note 2) For the type set to 0.2 MPa only, repeatability will be within ±3 kPa.
• *Note 3) Connection port threading is not provided for products with square embedded pressure gauges.
• *Note 4) The weight shown is for the product without any options.

Optional parts

• *Note 1) Assembly of a bracket and set nuts.
• *Note 2) The □ in the part numbers for round-type pressure gauges indicates the connection thread type. Insert no symbol for Rc thread, and use “N” for NPT thread. The G thread is not available. As such, select the R thread type (Nil) instead. Contact the manufacturer separately regarding NPT connection thread types and for psi unit specification pressure gauges.
• *Note 3) Including O-ring (1 pc.) and mounting screws (2 pcs.). [ ]: Pressure gauge cover only.
• *Note 4) Includes a lead wire with connector (2 m), adapter, lock pin, O-ring (1 pc.) and mounting screws (2 pcs.). [ ]: Switch unit only.
