FIELDS OF APPLICATION

In the field of oil and gas production and processing, explosion protected valve technology
is generally used. Depending on the field of application, the requirements can be very
different. The particular challenges onshore often include extreme temperatures and

OIL RIGS
Oil rigs have extremely high requirements for the technology
used. Even the smallest spark can have devastating
consequences for people and materials. To guarantee the
highest level of safety in those explosion hazard areas
atmospheres, all machines and their electrical equipment
are subject to stringent explosion protection standards, and
compliance with these must be proved by special tests and
relevant certificates.

OIL + GAS DRILLING SITES
Probing and drilling for oil and gas fields is not only a
technically difficult undertaking, it is also extremely hazardous
due to gases and liquids which suddenly appear. Apart from
a high explosion protection, the hydraulic valves directly in the
drill head in particular must provide a high robustness and
reliability, because a failure of a small valve will lead to a long
break in drilling and high costs as a result. In addition to the
proven explosion protection, the valves must also have a very
high corrosion resistance in a salt water environment and still
be able to function reliably in temperatures down to -60 °C.

GAS TRANSPORT
The energy sources obtained by the extraction process must
be taken away from the extraction site and separated in large
quantities. Pipelines or tankers are used for this. To control the
huge volume flows of highly explosive gases and liquids when
loading the tankers, or in the case of the pipelines so-called
ball valves are used. These are often operated by hydraulic
valves, and this technology is usually exposed to a harsh
environment.
