Most regulators use spiral springs as the loading device. It is important to reduce the load of these springs relieving
their loaders as much as possible. In some cases, some residual load may last, even though the spring is relaxed to the
limits of its housing.
There is not a recommendation about the frequency to change the repair kit due several different variables in the
process that changes installation by installation as, for example, process gas quality, service conditions etc. The repair kit
should be changed when the regulator has problems during operation, as leakage, increase in set pressure and also
others that become the quality and regulator performance different.
However, Gascat recommends that after all regulators opening during maintenance service the repair kit must be
changed. It is also indicated to change a complete repair kit and not only specific part (example o’ring, obturator), to have
the all spare parts with same life time.
Gascat already inform to avoid all non original and genuine parts.
2 – INTRODUCTION
2.1 – SCOPE OF MANUAL
This Instruction manual has as objective supply information about operation, installation and maintenance about BRISE
PLUS pressure regulator manufactured by GASCAT.
2.2 – DESCRIPTION
Brise Plus pressure regulating valve was designed by Gascat’s Engineering to assist many different applications and
service conditions according to valve configuration. Brise Plus series is a pilot pressure regulating valve and it can be
utilized with all non-corrosive gas group and for corrosive gases when built in special versions.
Due “top entry” characteristics it is not necessary to remove the valve of the pipe for maintenance service or clean up
the regulator. Brise Plus also is recognized by robust construction, high performance, with accuracy of + 2.5% (or better
depending on the configuration -
1%), with high flow capacity.
Brise Plus Series was designed specially for gas distribution in low pressure or any other application where is necessary
an excellent regulation and low lock-up.
2.3 – SPECIFICATIONS
2.3.1 – AVAILABLE CONFIGURATIONS
BRISE PLUS SC: Pilot operated pressure regulator spring to close (fail close).
BRISE PLUS pressure regulators are classified as SC in accordance with standard DIN EN 334 directives, for fail
condition.
