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 fluoroelastomer 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. |
