The guidance for installation, operation and maintenance of ROFI
Valves contained in this manual, is
intended for use with our standard products. It may also be used with special valves provided the special
additional instructions are observed. These are available on request. These instructions should ensure
trouble-free fitting and safe operation of our valves, and form also the basis for any guarantee claims that
might arise.
Attention !
In terms of their hazard potential, valves and associated fittings should be treated on a
par with pressure vessels. Their design, installation and maintenance should therefore be based
not just on these instructions but also on the relevant Accident Prevention Regulations, Codes of
Practice and specialist literature. The handling and use of valves and fittings should only be
entrusted to properly trained personnel.
2. General Information
The design of the valve depends upon the use and is beneath the responsibility of the buyer. With the
application for mediums and temperatures which differ from the type description, it has to be consulted
with the manufacturer or the distributor respectively. The operating instruction is made for valves - gate
valves, globe valves, ball valves, swing check valves, strainers. It refers to valid standards and rules and
regulates order, fitting and operation. The instructions cannot replace qualified personnel. Technical
changes at the valves as well as changes of this description are in the responsibility of the manufacturer.
All valves are provided according to DIN EN 19 with sprinkled or rather stamped signs for the nominal
pressure (PN), nominal diameter (DN), construction materials, manufacturer's mark, and as far as
necessary with a directional marker. Before leaving the factory they are tested according to DIN 3230 (or
corresponding special agreements) with 1,5 fold nominal pressure for safety and tightness of the body by
internal pressure test. The seal is tested in any case, if nothing else has been agreed, with 1-fold nominal
pressure.
