Safety Instructions
• This "Instruction manual" has to be kept on the place, which can be easy reached .
• The regulator has to be used only for dry and clean gases . Never use with oxygen:
risk of explosion .
• The national norms and standards about installation, start-up and maintenance of the devices and gas instal-
lations have to be strictly respected .
• The handling with the device has to be done carefully, specially by the installation works . The pick up has to
be made by using the stretcher eyes or belts .
• The device should be examined before the installation for possible transport damages and be mounted only
if it is in perfect state . Possible lacquer damage should be improved . The sealing surfaces of the threaded
connections or flanges must be damage-free and clean .
• For reading off the device and its serving are sufficiently space to designate .
• For the protection of the device is recommendable to install a filter .
• The device is to be installed in such a way that it is not impaired in its function by other installation compo-
nents .
• The regulator has to be mounted in the pipe line without any tension .
• The mentioned below torque's values for screws (property class 5 . 6 ) must be respected by tighten of the
flanged connections:
Thread female
3⁄4 / 1" / 1 1⁄2"
DIN 2999/ISO 7
PN16
80 / 110 / 140
PS = 8 bar
ANSII50
80 / 110 / 140
PS = 8 bar
• These torque's values are mentioned per screw and are valid for metal soft material gaskets
(specified as k0xKD=45bD und k1=2,2bD). Other gaskets can require another torque's values.
• The screws used for the flange connection must be according to the flange size and must be adapted to the
température range of the regulator . Please tighten the screws crosswise .
• After the installation works are completed, the tightness of the connections (threaded or flanged) must be
checked with appropriate means .
• The operating conditions indicated on the name plates must be respected; if necessary appropriate safety
devices have to be designated .
• Repairs of the device are allowed to be made only by trained or qualified personal . Afterwards a tightness
test with 1 . 1 X PS must be performed . When changing pressure containing parts their compliance with PED
must be assured . After guarantee only with repair by Dresser Actaris Gas .
• The device has to be regularly examined for corrosion danger in the interior and external area and be taken
from use if noticeable corrosion is discovered .
• The internal chamber volume on the inlet side of regulator 233-8/-12, DN 40/50 is 1,0 litres. The chamber
volume on the outlet side of regulator 233-8, DN 40/50 is 2,5 litres and of the regulator 233-12, DN 40/50
4,8 litres.
• The device must be cleaned with a wet cloth only . The cleaning of the devices has to be done without using
any alcohol containing solvent or cleaning agents .
• The device is not appropriate for floods and loads by earthquakes .
• The pressure has to be completely discharged before to take the device from the pipe line . The rest of gas
can withdraw; therefore the required ventilation has to be insured .
• The appropriate measures for noise reduction have to be seized depending on the installation place and
work conditions .
