Series
BV3 ball valves feature sanitary clamp ends for
easy line removal. The sanitary polish is ideal for use
in pharmaceutical, food & beverage, and chemical processing
systems, while the cavity filler aids to reduce product
entrapment, and the full bore design provides consistent
flow characteristics. Best of all, Dwyer Instruments' ball
valves are economical and durable.
The BV3 Series 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 the valve open or closed,
while the modulating actuator accepts a 4 to 20 mA input
for infinite valve positioning. Actuator features 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
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.
