P pressure regulator plate
Identifier R1−...−6 or R1−...−10
Ident. code: ZF or ZA
Function:
Regulates the operating pressure in duct (1)
upstream of the directional control valve
AB pressure regulator plate
Identifier R4−...−6 or R4−...−10
ID code: ZI or ZD
Function:
Regulates the output pressure in ducts (2) and
(4) after the directional control valve.
Note:
This pressure regulator plate cannot be combi
ned with reversible 2x3/2−way valves (identifier
T32F−A, T32N−A, T32W−A)
Reversible AB−pressure regulator plate
Identifier R5−...−6 or R5−...−10
ID code: ZJ or ZE
Function:
Reversible pressure regulator for ports (2)
and (4)
Pressure regulation upstream of the direc
tional control valve
Conducts the operating pressure from duct (1)
to ducts (3) and (5)
Conducts the exhaust air from duct (1) to
ducts (3) and (5)
Notes:
Combination with standard 2x3/2−way valves
(identifier T32C−A, T32H−A, T32U−A) is not per
mitted
Reversible 2x3/2−way valves (identifier T32F−A,
T32N−A, T32W−A) need not be operated in a se
parate pressure zone if they are combined with
these pressure regulating valves.
