Pressure control valves type AGIR, AGIS, AGIU

two stage, subplate mounting, ISO 5781 sizes 10, 20 and 32

Table C070-14/E

Two stage pressure control valves with balan-

ced poppet designed to operate in oil

hydraulic systems.

AGIR: pressure reducing;

AGIS: sequence;

AGIU: unloading.

In standard versions the piloting pressure

of the poppet

햲

of the main stage

햳

regulated by means of a grub screw pro-

tected by cap

햴

in the cover

햵

Optional versions with setting adjustment

by handwheel

햶

instead of the grub screw

are available on request.

Clockwise rotation increases pressure.

Unloading valves AGIU can be equipped

with a venting solenoid valve

햷

type:

• DHI for AC and DC supply, with CURUS

certified solenoids

•

DHE for AC and DC supply, high

performances

with CURUS certified sole-

noids

Mounting surface: ISO 5781 size 10, 20 and 32

Max flow:

AGIR = 160, 300, 400 l/min

AGIS = 200, 400, 600 l/min

AGIU = 100, 200, 300 l/min

NOTES

1)Short pipes with low resistance must be

used between the unloading valve and

the accumulator;

2)When the resistance is high, the hydraulic

pilot signal must be taken as closed as

possible to the accumulator;

3)With high pump flow and small valve

differential pressure of intervention it is

unadvisable to use the version with

external drain;

4)When to use the BA-*25 subplates:

a) in applications with working frequencies

>10 Hz use subplates type BA-*25/4

(spring with 4 bar of cracking pressu-

re);

b) in applications with working frequencies

<10 Hz use subplates type BA-*25/2

(spring with 2 bar of cracking pressure);
