MAINTENANCE
The solenoid valve consists of 316 and
416 stainless steel, and VITON
7
(or
optional BUNA-N
7
, EPR or KALREZ
7
) O-
rings and seals. No regular maintenance
is required except for periodic cleaning.
Various corrosive gases or liquids may
demand more frequent replacement of O-
rings and seals inside the valve. Be sure
to use an elastomer material, appropriate
for your specific application. Contact your
distributor or Aalborg
7
for optional sealing
materials available.
Set the PSV for maximum flow, and
attempt to flush through in both directions
with a clean, filtered, and neutral gas such
as nitrogen. [Another option for fully open-
ing the valve is to remove the plastic cap
on top of the valve, and turn the set screw
counterclockwise until it stops]. If block-
age is not alleviated, return the unit to
your distributor or Aalborg
7
for servicing.
It is the users responsibility to determine
if the instrument is appropriate for their
OXYGEN application, and for specifying
O2 cleaning service if required. Aalborg
7
is not liable for any damage or personal
injury, whatsoever, resulting from the use
of this instrument for oxygen.
If the valve is left in the active mode for
an extended period of time, it may
become warm or even hot to the touch.
Use care in avoiding direct contact with
the valve during operation.
To protect servicing personnel it is
mandatory that any instrument being
serviced is completely purged and
neutralized of toxic, bacteriologically
infected, corrosive or radioactive
contents.
Use of the PSV valve in a manner other
than that specified in this instruction
sheet, may impair the protection
provided by the equipment.
