Customer: Petrochemical plant
Key benefits: Increased safety, ease of
installation
Case study
Requirement
One of the biggest challenges working
with high-value but potentially dangerous
materials such as crude oil, natural gas, or
petrochemicals is protecting and increasing
safety without disrupting process availability.
Redundant valve arrangements that continue
to function safely even if one or more valves
fail are the industry preferred solution. A
Gulf Coast plant wanted a redundant high-
integrity pressure protection system (HIPPS)
to prevent over-pressurization. A HIPPS acts
as a safety barrier between the high-pressure
and low-pressure sections of a petrochemical
plant. The piped system the plant was using
required frequent manual inspections and
maintenance to ensure reliability, made even
more difficult because there were no simple
monitoring options. The components were
also complicated and bulky. Plant engineers
were looking for an integrated pneumatic
control system that was more reliable, simple,
and compact.
Solution
IMI Precision Engineering already had a
proven solution – the IMI Norgren
®
Redundant
Valve Manifold (RVM). A single stainless steel
or aluminum valve block integrated with
SIL-3 capable IMI Maxseal
®
and IMI Herion
®
solenoid valves makes the RVM simple
to install, test, and maintain. IMI Precision

GREAT
Solutions
to build a two-out-of-three redundant valve
manifold with mechanical specifications
and a control alarm to meet their specific
HIPPS requirements. Tested at IMI Precision
Engineering's Littleton, Colorado, facility and
in the field, the RVM met customer's tough
technical evaluation as well as European and
U.S. certification standards. The compact
RVM is a price competitive, plug-and-play
replacement, certified to use in a SIL-3
environment. The customer can be use this
RVM on future projects and retrofits without
costly and time-consuming design changes.
