Extensively
used in large Pipe
Lines, Small Reactors/Vessels
to release pressure
Generated by thermal
expansion.

|
|
Auto
Re-circulation
on a Refueller
to control the
pumping pressure
of Air Crafts. |
|
|
Solenoid
Override or
Pneumatic Override
to safeguard
the system.
This can be
operated remotely
to re-circulate
full flow. |
|
|
When
installed in
Main line, it
prevents upstream
pressure dropping
below preset
value. |
|
|
When
installed on
a By-Pass line,
it controls
main line pressure
by relieving
excess pressure
in By-Pass/sump. |
|
|
Ideal
for pump by
pass to protect
the downstream
equipments.
|
|
|
Relief
pilot (F16)
is normally
closed due to
spring tension. |
|
|
With
increase in
upstream pressure
above set value,
Pilot (F-16)
opens which
makes Main Valve
to open fully.

Range: Standard:
20-200 psig.
Optional: 5-30
