THE SERIES WE06 incorporates a V-port
ball valve for impressive flow rates with
minimal pressure drop. Quarter turn
control ball valves are compact, lighter
weight and much less expensive than
comparable sized globe valves and
segmented control valves. They also offer
bubble tight shut off with zero leakage and
can withstand high pressure drops. The 60°
and 90° balls offer an equal percentage flow
characteristic. W. E. Anderson’s V-port ball
valves have been designed to offer
maximum flow characteristics that are
substantially higher than comparably sized
globe valves. The natural flow pattern of
ball valves increases flow rates and in many
applications valves smaller than pipeline
size can be used.
Actuators are directly mounted creating a
compact assembly for tight spaces. Limit
switches can be mounted directly to the
valves allowing for remote position
indication.
The Series WE06 can be configured with an
electric or pneumatic actuator. Electric
actuators are available in weatherproof or
explosion-proof, a variety of supply voltages
and two-position modulating control.
Two-position actuators use the supply
voltage to drive the valve open or close,
while the modulating actuator accepts a 4 to
20 mA input for valve positioning.
Actuators feature thermal overload
protection and a permanently lubricated
gear train.
The pneumatic double acting actuator uses
an air supply to drive the valve open and
closed. The actuator has two supply ports
with one driving the valve open and the
other driving the valve closed. Spring
return pneumatic actuators use the air
supply to open the valve and internally
loaded springs return the valve to the closed
position. Also available is the SV3 solenoid
valve to electrically switch the air supply
pressure between the air supply ports for
opening and closing the valve. Actuators are
constructed of anodized and epoxy coated
aluminum for years of corrosion free
service.
