Three-way automated ball valves

WE Anderson, a division of Dwyer Instruments, has released the Series 3BV2 automated ball valves with three-way SS flange.

The Series 3BV2 incorporates a full port design for maximum flow rates with minimal pressure drop. The Series 3BV2 is suitable for use in a variety of applications including the food and chemical processing industries.

These ball valves feature a blowout-proof stem and reinforced RTFE seats for added safety, longer life and leak-free operation. The four-seat design allows for high cycling automation. The 3BV2 comes with a choice of either pneumatic or electric actuators.

Two pneumatic actuators are available. The double-acting pneumatic actuator uses an air supply to drive each of the actuator ports while the spring-return pneumatic actuators use an air supply to drive the valve stem in one direction and an internally loaded spring to return the valve to its original position. These actuators are constructed of anodised aluminium and are epoxy coated for years of service.

The electrically actuated models have NEMA 4 enclosures with an optional explosive-proof, NEMA 7 enclosure. The electric actuators are available in either two-position or proportional control with a standard 115 VAC supply. The modulating actuator accepts a 4-20 mA input for variable valve positioning while the two position actuators use the 115 VAC input to position the valve opened or closed. The electric actuator features include thermal load protection to withstand stall conditions, visual position indication and a permanently lubricated gear train.
