OmniSeal expanding plug valves are ideal for applications that require
positive shut-off, verifiable zero leakage and double block and bleed (DBB)
capability. Some of the more common applications include:
Blending Units
Accurate blending of
ethanol or other regional fuel grades requires valves with exceptionally
high seal integrity to ensure accurate measurement of additives and blending
stocks. The OmniSeal® DBB is specifically designed for applications of this
type.
Product Isolation
Secure isolation of
Biofuels or other process-sensitive fluids is critical for environmental and
process safety. The OmniSeal® DBB’s verifiable zero leakage and positive
shutoff capabilities make it an ideal solution for isolation and
process-sensitive applications.
Multi-Product Manifolds
Pipeline, refinery
and transfer manifolds need to flow multiple products (e.g. diesel, jet fuel,
gasoline, blending stocks, etc.) reliably and without contamination. The
OmniSeal® DBB is an effective tool for preventing product
cross-contamination.
Prover Loops
Proper calibration of
flow meters requires that every valve in the prover loop system must have a
zero leak rate. Any leak could mean an error in calibration. OmniSeal® DBB
valves are used to ensure leak tight closure and accurate calibration.
Custody Transfer Units
Transfer of valuable
media relies on accurate measurement of product transfer quantity. The
OmniSeal® DBB provides positive shutoff and zero leak rate, thereby ensuring
accurate calculation of transfer quantity.
Offshore Platforms
Valve leakage on an
offshore platform can result in damage to equipment and the environment. The
OmniSeal® DBB has excellent low pressure positive shutoff characteristics
and is a great choice for use on offshore platforms.
Terminals
Terminals used for
loading and unloading tankers require valves with positive sealing in order
to prevent environmental damage due to spillage. The OmniSeal® DBB provides
positive sealing and zero leak rate in a reliable single valve solution.
Tank Farms (Oil Depots)
Tank isolation
valves, which are operated frequently, require zero leak rate and a high
degree of reliability. The OmniSeal® DBB valve provides a reliable high
integrity seal designed for frequent and longterm use.
Aviation Fueling Systems
Airport fueling
systems require valves that close quickly and have verifiable seal
integrity. This allows for quick maintenance, repair, leak location and
testing. The OmniSeal® DBB valve’s verifiable zero leak rate ensures that
maintenance, repair, leak location and hydrant testing can be done safely
and quickly.
