1.2 8810 Description
Tradinco Instruments 8810 reducer is designed for precision control of gas pressure in
closed-end systems up to 350 bar.
Rotational movement of the control knob, which compresses or decompresses the spring
loaded mechanism, is transferred with a ball bearing to improve smooth operation. This
results in more precision when reducing high pressurised gases.
Pressure ranges ranging from 16 to 350 bar.
Both the inlet and outlet ports are equipped with monitoring ports. The inlet port is also
equipped with a 20 μ particle filter. All pressure ports have a 1/8 NPT female connection.
When the controlled outlet pressure is lowered, the 8810 reducer will vent the over
pressure through the internal venting system.
The 8810 reducer can be fitted into a panel.
1.3 Symbols Used
Warning for conditions or practices that could result in personal injury, loss of life
and/or in damage to the product or other property.
Attention signal or remark
1.4 Scope of this manual
This manual contains information for instruments built after January 2014.
This manual is a user manual on how to operate the instrument; it is not a calibration
instruction manual.
As Tradinco Instruments continuously strives to improve its products, specifications of
instruments may be altered without further notice
1.5 Use
The 8810 reducer is used to reduce a supply pressure to a set outlet pressure.
The 8810 reducer must not be used as flow regulator and/or shut of device.

2Installation
The instrument can only be installed by trained personal.
Check tread of the pressure ports and fittings before installation and make sure
they are clean and not damaged.
Tapered NPT treads usually are screwed in together with Teflon tape to protect
against galling and to improve sealing. It is important that no remains of the
tape are able to get into the interior of the reducer.
2.1 Transport and packing
The 8810 reducer is delivered in a dust free carton box to prevent contamination in the
instrument. When the 8810 reducer is transported or stored, it is advised to put it in the
original carton box, or plug the pressure ports. This can also be done by sticking tape
over the pressure ports, so that the mechanical workings of the instrument cannot be
contaminated.
2.2 Assembly
Connect the supply and outlet ports with 1/8 NPT male couplings into the closed-
end system
Turn the reducers fully counter clockwise.
Supply pressure to the reducer
Turn the control knob clockwise until the reduced test pressure is available on the
outlet port.
Check for leaks
If any leaks are detected; turn the control knob fully counter clockwise, relief
pressure of the entire pressurised system, eliminate the leaks and repeat
procedure from step “Supply pressure to the reducer” until no leaks are detected.
Be careful, you are working with high pressure compressed gases.
2.3 Assembly of 8810 into panel
Remove the logo plate on the control knob by taking out the two small screws.
Remove the lock nut
Remove the control knob
Remove front ring
Cut a panel hole of 35 mm
Fit the reducer behind the panel
Install the front ring
Fix the reducer with the big lock nut
Connect the supply and outlet lines
Turn the reducers fully counter clockwise.
Supply pressure to the reducer
Turn the control knob clockwise until the maximum required test pressure is
available on the outlet port.
Check for leaks

3Operation
Allways open and close valves slowly. Allways use the appropriate gases wich
must be dry and clean(free of oil).
Influence of supply pressure on controlled outlet pressure.
The 8810 reducer has been designed for minimum influence of supply pressure to
the controlled outlet pressure.
However controlled outlet pressure my rise up to ±2 bar when the supply pressure
is decreased from full to zero.
This behaviour in particular can be observed on installations fed from a
compressed air/N2 bottle supply.
In case process pressure fed by the 8810 reducer is critical, the operator should
take care to adjust the setting / replace the supply bottle before controlled
pressure problems arise.
The reducer vents into the open air when releasing pressure. When working with
other gases than compressed air this can result in displacing the oxygen from the
air and/or releasing toxic gases into the air. A non venting option for the 8810
reducer is available, however with this option; pressure cannot be released trough
the reducer.
3.1 Leakage check
Unload the reducer by turning the control knob fully counter clockwise.
Close the outlet with a plug or valve
One of the outlet ports must be connected to a pressure gauge.
Turn on the inlet pressure supply.
Adjust the reducer to the maximum outlet pressure by turning the control knob
clockwise.
Check the external connections for leakage.
Check for internal leakage. Wait for 15 minutes and check if the outlet pressure
stays constant. The outlet pressure must not rise.
Close the pressure supply and vent the regulator by turning the control knob fully
counter clockwise.
3.2 Initiation
Unload the reducer by turning the control knob fully counter clockwise.
Close all consumers downstream of the regulator.
Open the supply pressure on the inlet.
Adjust the outlet pressure by turning the control knob clockwise.
3.3 Out of operation
Close the pressure supply and vent the regulator by turning the control knob fully
counter clockwise.
3.4 Out of operation and taken out of pressurised system
Close the pressure supply and vent the regulator by turning the control knob fully
counter clockwise.
Also vent the pressure supply of the reducer before dismantling the 8810 reducer
out of the pressurised system.

4Maintenance
An inspection is recommended every 6 months. The reducer most be checked on outside
damages and functionality.
When checking the reducer, the spindle must be creased with copper grease to ensure a
smooth working of the spindle in the reducer. This is done by:
Close the pressure supply and vent the regulator by turning the control knob fully
counter clockwise.
Remove the logo plate on the control knob by taking out the two small screws.
Remove the nut
Remove the control knob
Apply copper grease at the base off the spindle.
Put the control knob back on the spindle and turn the control knob a few times
fully clockwise and counter clockwise.
Take of the control knob and remove excess copper grease.
Install the control knob with the locknut
Install the logo plate.
Further overhaul and replacement of all wearing parts must be done by Tradinco
Instruments. It is recommended every 5 years, more frequent maintenance may be
needed when the system is used under extreme conditions.
