Dwyer Instruments, Inc.
Dwyer Instruments introduces its W.E. Anderson series BV3-3A ball valves, which meet 3A sanitary standards and feature sanitary connection ends for easy line removal. The cavity-filled and full-bore designs aid to reduce product entrapment, and provide consistent flow characteristics.
The BV3-3A Series is an economical, automated valve packaged with either an electric or pneumatic actuator. Electrically-actuated models have a standard weatherproof, NEMA 4 enclosure, powered by a 115 VAC supply, and are available in either two-position or proportional control. The 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. The actuator features a visual indicator, manual override, thermal overload protection and permanently lubricated gears.
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, according to Dwyer. Series BV3-3A automated three-piece ball valves are competitively priced starting at $326.50.
