Group 31 Compact Valve Actuators
Group 31 compact valve actuators are designed
for coupling to small quarter-turn ball and
butterfly valves. The compact, in-line design
consists of an output section housing the drive
train and motor, and a control module section
containing the electronics. Together, these two
sections provide an enclosure designed to meet
NEMA 4 specifications for protection against
corrosion, dust, and moisture.
The Group 31 incorporates the same type of
motor used in Beck’s Group 11 and Group 14
drives. It provides millisecond response to signal
commands in a modulating control loop. This noburnout, non-coasting motor is capable of more
than 60 starts per minute during process upsets
and will remain cool and stable during operation
for unparalleled on-line performance.
Group 31 compact valve actuators are
engineered for direct coupling on quarter-turn
ball and butterfly valves. They may also be
installed using specially engineered crank arm and linkage
arrangements.
Valves and drives may be ordered together as pre-engineered
assemblies ready for drop-in installation. Or drives can be supplied
separately along with the necessary hardware for field installation on
existing valves.
