T
hrottle/check valve type
Z2FS22.
.
.
is sed for setting the
size of the main or control flow in one direction, and allow
free flow in the opposite direction. The Z2FS22…
type
valve is a do ble throttle/check valve. Two symmetrically
positioned against each other throttle/check valves limit
thro gh adj stable throttle (throttling piston) size of the
flow in one direction, and allow free flow in the opposite
direction thro gh the check valve. The valve is desig
ned
for sandwich type mo nting -
it is s ally installed
between the s bplate and the valve of the same nominal
size and is sed for limiting the size of the main flow
(changing the speed of movement of the receiver).
Hydra lic fl id from the port
A
flows thro gh the
throttling slot (1) to the receiver. At the same time, the
fl id nder operating press re flows thro gh port (2) to
the side (3) of the piston (4) which is loaded with the
spring. The piston (4) is therefore maintained in the
throttling position both by the force of the spring and the
hydra lic force. The fl id ret rning from the receiver
moves the piston (5) to the right and allow free flow of
the fl id thro gh the valve system (throttling insert)
which now acts as a check valve.

INSTALLATION AND OPERATION REQUIREMENTS
1. Only f lly f nctional and operational valve, properly
connected to electrical installation m st be sed.
2. D ring the period of operation m st be kept fl id
viscosity acc. to req irements defined in this Data
Sheet - Operation Man al
3. In order to ens re fail re free and safe operation the
following m st be checked:
• proper working of the valve
• cleanliness of the hydra lic fl id
4. D e to heating of valve body to high temp., the valve
sho ld be placed in s ch a way as to eliminate
possibility
of accidental contact with the valve body
d ring operation or one sho ld provide s itable
shields in accordance with req irements of EU
standards: PN - EN ISO 13732-1 and PN - EN ISO 4413.
5.
In order to provide tightness of the valve connection
to a hydra lic system, one sho ld follow the
sizes of
sealing rings, tightening torq es and work
parameters of the valve given in this Data Sheet
-
Operation Man al
6.
A person that operates the valve m st be thoro ghly
familiar with this Data Sheet - Operation Man al.
