Dwyer ABFV - Manual (Page 2)

The ABFV Series is offered with standard 316 SS disc, a
through shaft that does not come in contact with the media, and
choices of EPDM, BUNA-N, or fluoroelastmer liners for great
chemical compatibility. Valve design has integral ISO mounting for
direct mount actuators creating a more compact automated
package. Body is epoxy coated for durable and attractive finish.
Liner fully covers the body and assures tight seal with mating
flanges without additional gaskets. One-piece shaft ensures
positive valve positioning and is an anti-blowout design.
ABFV valves come in two-way and three-way packages. Three-
way assemblies include valves and actuators mounted onto a
125# cast iron tee. When ordering you have the choice of valve
arrangement for mixing or diverting applications. Valves come in
lug or wafer style and wafer models have guide holes for bolts.
ABFV is an economical automated valve package with either an
electric or pneumatic actuator. Electrically actuated models are
weatherproof, NEMA 4, powered by standard 115 VAC supply,
and are available in either two-position or proportional control.
Two-position actuators use the 115 VAC input to drive each of the
valve ports open or closed, while the modulating actuator accepts
a 4 to 20 mA input for infinite valve positioning. Actuator features
include thermal overload protection to withstand stall conditions,
visual position indication and a permanently lubricated gear train.
The pneumatic double acting actuator uses an air supply to drive
each of the actuator ports. Spring return pneumatic actuators use
the air supply to drive the valve stem one direction, and internally
loaded springs return the valve to its original position. Also
available is the SV3 solenoid valve to electrically switch the supply
pressure between the air supply ports. Actuators are constructed
of anodized aluminum and are epoxy coated for years of corrosion
free service.
