Introduction
This Installation Guide provides instructions and safety
information on pressure equipment so as to avoid any
foreseeable risk during the use.
For further information refer to Types MN Instruction
Manual, n° 0125 and Bulletin, n° 0120.
To receive a copy of the Bulletin, contact your local O.M.T.
Tartarini Sales Office or O.M.T Tartarini Sales
Representative.
General Remark
The standard gas pressure devices (regulators and safety
shut-off devices) are those used in the assemblies dealt
with into EN 12186 and EN 12279 and their use has to be
under the provisions into ENs 12186 & 12279.
Fail-to-open stand-alone regulators cannot be used as a
safety accessory according PED 97/23/EC to protect
downstream pressure equipment.
In the pressure regulators (with or without built-in safety
shut-off devices) manufactured by OMT Tartarini shall be
used additionary pressure accessories (e.g. pilots or
filters) manufactured and labeled by OMT Tartarini.
OMT Tartarini will be not responsible for any possible
inefficiency due to installation of not own production
additionary pressure accessories (e.g. pilots or filters).
When pressure containing parts of possible built-in safety
shut-off device (SSD) valve and pilot have different
maximum allowable pressures, the SSD is differential
strength type.
P.E.D. Categories and Fluid Group
According to EN 14382, only in integral strength type and
Class A configuration (when both over and under pressure
protections are set up), the possible built-in safety shut-off
device can be classified like a safety accessory according
to PED.
The minimum PS between SSD valve and pilot shall be
the PS of the safety accessory to comply the provisions of
EN 14382 about integral strength type.
Downstream equipments, protected by possible built-in
safety shut-off device (in its Class A and integral strength
configuration) of this product, shall have technical features
such as to be category per table below according Directive
97/23/EC “PED”.
