SAFETY INSTRUCTIONS
• This "Instruction manual" has to be kept on the place, which can be easy reached .
• The safety shut-off valve 022 is 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 installations
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 .
• The device is to be installed in such a way that it is not impaired in its function by other installation components .
• The screws used for the flange connection must be according to the flange size and must be adapted to the temperature
range of the regulator . Please tighten the screws crosswise .
• For the flange connections use screws whose shaft exceeds the nut by at least one thread .
• The safety relief valve has to be mounted in the pipe line without any tension . The torque (for the screws property
class 5 . 6 ) given in the following table, should not be exceeded:
PN 16
ANSI 150
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.
• 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 inner chamber volume of the SSV 022 amounts to:
DN
1"-NPT
V in Liter
• The device must be cleaned with a wet cloth only . Please don't use solvent or alcohol containing products to clean
the regulator .
• 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 .
REMARKS FOR USE IN POTENTIALLY EXPLOSIVE ATMOSPHERES (ATEX):
• If film of rust is possible (flying rust in the immediate product surroundings), all outer aluminum parts have to be
protected accordingly (e . g . by varnish) .
• The product must be electrically connected to adequately earthed installation .
• For installation, removing or repair of the product on site, only tools allowed for the corresponding explosion area can
be used .
• The product shall not be exposed to: flames, ionised radiation and ultrasound .
• Ambient temp . conditions must be considered, including possible additional heating effects due to other devices in
immediate vicinity .
• Safety Shutt of valve according to EN14382 - if not equipped, with any electronic device - do not have a potential
ignition source and therefore are not in the scope of European directive 2014/34/EU .
