Valve terminals type 32 MPA
Key features – Pneumatic components
Vertical stacking
Mode of operation of the pressure regulator plate (P regulator) for port 1; code: PA, PF
This pressure regulator regulates the
pressure upstream of the valve in
duct 1. Ducts 2 and 4 thus have the
same regulated pressure.
During venting, the exhaust flow in
the valve is from duct 2 to duct 3 and
from duct 4 to duct 5.
Advantages Application examples
•
The pressure regulator is not
affected by venting, since the
pressure is regulated upstream of
the valve.
•
The pressure regulator can always
be adjusted, since the pressure
from the valve terminal is always
present.
•
An equal working pressure is
required at working ports 2 and 4.
•
A lower working pressure
(e.g. 3 bar) than the operating
pressure present at the valve
terminal (e.g. 8 bar) is required.
Mode of operation of the pressure regulator plate (B regulator) for port 2; code: PC, PH
This pressure regulator regulates the
pressure in duct 2 after the pressure
medium flows through the valve.
During venting, the exhaust flow in
the valve is from duct 2 to duct 3 via
the pressure regulator.
Restrictions Application example
The pressure regulator can only be ad-
justed in switched state (e.g. the valve
is switched to 2 and exhaust flow
occurs from 4 to 5).
The pressure regulator makes it
possible to reduce the pressure at port
2 of an individual valve, in contrast to
the operating pressure of the valve
terminal.
