UNISIG – 2” Valve Mounted (Flange)
Product: Pig Signaller
Grouping: Pressure vessel
Version: 1.0
General function and application:
Pig signallers are fitted to launcher
and receiver stations to confirm the
launch / arrival of a pig. They can
also be at any location along a
pipeline length to give indication of a
pig at a specific location, e.g. road
and rail crossings. Also, other
pipeline features such as valve
stations, bends and tees. They can
be used to detect the passage of all
types of pigs from foams, spheres,
and metal-bodied pigs to intelligent
inspection tools.
UNISIG offers a cost effective, reliable signalling
system. Incorporating a simple magnetic/mechanical
design, which reduces the number of moving parts.
This reduces initial capital costs, running & maintenance
costs and in-turn; down time of your pipeline.
The design incorporates a unique magnetic system,
which allows for the use of static seals. This means
reduced risk of product leakage.
In addition to being deigned for manufacture, to keep
costs to a minimum, the UNISIG is also designed for
ease of operation, therefore is simple to use and
maintenance can be carried out in a fraction of the time
of older designs.

design the UNISIG can be supplied with an integrated
range of valves, including 2” flanged single, or double
isolation valves to offer Double-Block-Bleed.
