Manometer
If pressure reducing valve type 582/pressure retaining valve type 586 is a
manometer version, then the manometer is already fitted at the factory.
5Function
5.1 Pressure reducing valve
On the side of the valve outlet, the pressure acts via the diaphragm on the adjustable spring.
A balance of forces is established via the preloaded spring, which is set with the adjusting
screw at the valve. If the outlet pressure increases above the specified value, the piston is
lifted against the spring force. The valve closes, and the outlet pressure is reduced. If the
outlet pressure decreases below the value, the piston is pushed down by the spring
resistance. The valve begins to open, until the balance is reached again. Independent of an
increasing or decreasing inlet pressure, the outlet pressure remains constant to the greatest
possible extent, because it is not directly related to the inlet pressure.
5.2 Pressure holding valve
The desired pressure in the valve inlet pipe is set by the adjustable spring force. If the inlet
pressure rises above the set value, e.g. due to an over capacity of the pump, the valve piston is
lifted against the spring force. Consequently, the valve opens, and there is a reduction of
pressure in the outlet. If the pressure decreases in the valve inlet pipe, the spring resistance
pushes the piston down in the direction of the valve seat and closes, as soon as the inlet
pressure sinks below the preset spring tension. In this way, a constant pressure in the supply
line is ensured.

WARNING –ONLY FOR MANOMETER VERSION
Danger of material damage and/or injury due to changes of the manometer!
Valid for versions with and without adaptor.
The manometer is installed, preset and checked at the factory. Therefore,
ensure that no changes are made at the manometer.
The valve bodies are suited for various connection types:
Connection: radial installation and removal
Connection: spigot ends
Pressure reducing valves type 582/pressure retaining valves type 586 are supplied
with released spring.

Installation Instruction manual
36
Ensure that pressure reducing valve type 582/pressure retaining valve type 586 is suited
for operating conditions, see label.
Check pressure reducing valve type 582/pressure retaining valve type 586 on damages
before installation. Do not use any damaged or faulty product.
Ensure that the installation of pressure reducing valve type 582/pressure retaining valve
type 586 is carried out without tension.
In order to ensure an optimum flow rate, ensure that
-pressure reducing valve type 582/pressure retaining valve type 586 is installed
in a section of the pipeline that is not subjected to turbulent flow and that
-bends, restrictions, shut-off devices have a minimum distance of 10 x DN from
pressure reducing valve type 582/pressure retaining valve type 586.
Observe the flow direction, see arrow on body (Fig. 1)
Fig. 1
Observe connection types, see versions of „radial installation and removal“ and „spigot
ends“.

Instruction manual Installation
37
Type „Radial installation and removal“:
Loosen the coupling nut and slide it on the intended pipe end.
Connect the connection parts with the pipe ends. For instructions concerning the different
connection types, see planning fundamentals.
Put pressure reducing valve type 582/pressure retaining valve type 586 between the
connection parts.
Tighten the coupling nuts by hand.
„Spigot ends“:
If adapted to flange version, observe the tightening torques of the flanges, see „Georg
Fischer planning fundamentals“.
In order to protect against soiling and premature wear and tear by erosion, we
recommend installing a strainer on the inlet side of pressure reducing valve type
582/pressure retaining valve type 586.
Cemented connection
Only join identical materials.
After the curing time of the joint has elapsed, rinse the pipe section as quickly as possible
with pressure-less water, see Chapter „Jointing techniques” in the „Georg Fischer
planning fundamentals”
Welded connection
Only join identical materials, see Chapter „Jointing techniques” in the „Georg Fischer
planning fundamentals”.

11 Maintenance
WARNING
Risk of injury due to uncontrolled evasion of the medium!
If the pressure was not relieved completely, the medium can evade uncontrolled.
Completely relieve pressure in the pipes prior to
dismounting/maintenance/dismantling.
In case of harmful, flammable, or explosive media: Completely empty and rinse
pipe prior to dismounting. Pay attention to potential residues.
Make sure that the medium is caught safely with the appropriate measures.
Difficult opening, due to pretensioned spring. Make sure that the spring is
completely relaxed before opening the bonnet assembly (top part). To do so, turn the
spindle counterclockwise (P-), up to the end position.
CAUTION
Risk of injury and missing product quality through use of spare parts that have
not been provided by GF Piping Systems!
Only use the listed spare parts, see Chapter List of Spare Parts.
Set maintenance intervals as per the conditions of use (e.g. actuating cycles, medium,
ambient temperature).
As part of the regular system inspection, carry out the following maintenance activities.
