Dwyer Instruments' Series WE03 automated, three-piece, tri-clamp, stainless steel ball valves provide high flow rates with minimal pressure drop. They can be configured with either an electric or pneumatic actuator. Electric actuators come in weatherproof or explosion-proof versions, a variety of supply voltages, and with two-position, modulating control. Pneumatic double-acting actuators use an air supply to drive the valve open and closed.
