| Advanced
Valve Technologies specialises in the production of a range
of both off-the-shelf and custom-built Valves specifically designed to
meet the demands of harsh or extreme environments. Construction is of reinforced
composites which give remarkable resistance to corrosion, abrasion and
impact, significant weight saving, excellent tensile strength throughout
a wide range of operating temperatures and very low thermal conductivity.
Valves can be operated manually or remotely.
Advanced
Valve Technologies Valves incorporate all the features which
users have come to expect from high performance valves combined with the
significant advantages available from reinforced composite resin systems
tailored to provide optimum characteristics for specific applications.
The range used includes Glass Reinforced Epoxy, Vinyl Ester and Novolac
Epoxy systems formulated to achieve extended service lives in demanding
applications without a requirement for routine maintenance. Continuous
research and development ensures that the range maintains its technical
leadership at all times.
Remarkable
internal corrosion resistance of all Advanced Valve Technologies
resin systems eliminates the need for internal protective linings. The
key to corrosion resistant performance lies with the careful specification
of Body, Ball and Trim materials.
-
Excellent alternative
to thermoplastic valves that offer limited pressure-temperature performance
resulting in possible short life cycles
-
Cost effective
alternative to stainless steel valves that may suffer from corrosion or
process build up/blocking
-
Preferred alternative
to high cost exotic metal valves or PTFE lined products
Light
weight materials provide significant advantages leading to substantial
reduction of costs for installation, delivery to site and subsequent maintenance.
-
Cost saving alternative
to metal valves in installations where frequent maintenance work and replacement
is necessary through easier handling
-
Cost saving alternative
where weight saving is important - Offshore platforms, marine applications,
remote land sites
-
Ideal valve for
installation into plastic and GRP piping systems or into plastic tanks
as they eliminate the need for structural support, thereby reducing pipeline
stress issues
Typical
weight savings - 40%
Good
abrasion and cavitation resistance Reinforced composite systems
resist damage caused by abrasion, erosion and cavitation. |

Remarkable
external corrosion resistance of all Advanced Valve Technologies
resin systems eliminates the need for external protection.
-
Superior for process
areas which suffer environmental attack in a chemical-laden atmospheres
- Chemical plants including effluent pits
-
Ideal for exposed
areas subjected to seawater and salt water spray - Coastal and estuary,
marine and offshore applications
-
Selected for buried
pipeline service with soil contamination problems - fire water ring mains,
effluent disposal, cooling pond connections, product distribution
Very
low thermal conductivity of Advanced Valve Technologies resin
systems eliminates the need for external lagging or trace heating even
when such treatment of associated pipes is necessary.
-
The high level
of insulation reduces process heat loss - saving installation costs of
lagging or trace heating plus process energy costs
-
Elimination of
valve jackets in most applications otherwise requiring these offers additional
installation cost savings
-
Reduces or eliminates
occurrence of process freezing due to heat loss - reducing resultant process
flow problems
Very
low galvanic conductivity avoids any risk of galvanic reaction
with metal pipes or fittings.
-
Reduces cost of
sacrificial anodes
Extended
operating temperature range at full rated pressure Resin systems
offered permit operation at full rated pressure subject to media through
temperature range -40°C to +140°C. |
All valves
are produced to ANSI 150, ANSI 300, BS and DIN specifications
