Series ARP20/30/40

Direct Operated Precision Regulator

CAT.EUS40-52A-UK

AF AFM ARP

AF AFM VHS

ARP20K/30K/40K

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.

AF AFM ARP

∗ Cylinder: Non-lube type

∗ Solenoid valve:

Non-lube type

 Residual pressure circuit

Also exhausts the residual pressure completely.

Application of a constant pressure to the fluid.

Applications

Direct operated precision regulator

now available as a series!! (ARP20/30/40)



Expanded lineup



3 types of set pressure and the body size

allow more freedom in designing a circuit.

SettingPort size

Control of a clamping force by a precise

pressure control.

Sensitivity within 0.2% F.S. allows a more precise pressure

adjustment. Repeatability within ±1% F.S. (or within

±0.3 kPa) allows a constant clamping force.

Release of the residual pressure with the

backflow function.

Adjustment of the blow-line pressure.

Sensitivity within 0.2% F.S. allows a more precise pressure adjustment.
