Control valve specialist,
Samson Controls, has
enhanced its established Type
3291 valve and Type 3730-6
positioner to provide additional
features and added value.

The Type 3291 Valve combines
the proven V-port plug and
clamped-in seat and is
particularly suited for use
under severe operating
conditions, such as in the
oil, gas and petrochem
industries. The smooth interior
surfaces of the valve make it hard for
deposits to form so the potential for
the valves clogging is minimised.

The type 3730-6 positioner with
HART communication is a further
development of the successful Series
3730 positioners. The standard
version is supplied with the
proven EXPERTplus valve
diagnostics that allow the entire
operating cycle of control valves
used in throttling or on/off service
to be monitored.

Another feature is partial stroke
testing (PST) that provides
information on whether shutoff
valves function properly
on demand and can be
started by hand or automatically.
