The Series WE33 incorporates a full port3-way tri-clamp SS ball valve for great flowrates with minimal pressure drop. Thevalve features a blowout-proof stem foradded safety, reinforced PTFE seats andseals for longer life, and a 316 SS (ASTMCF8M) ball for better performance.Actuators are direct mounted creating acompact assembly for tight spaces. Limitswitches are able to be mounted directly tothe valves allowing for remote positionindication.
The Series WE33 can be configured witheither an electric or pneumatic actuator.Electric actuators are available inweatherproof or explosion-proof, a varietyof supply voltages and two-position ormodulating control. Two-position actuatorsuse the supply voltage to drive the valveopen or close, while the modulatingactuator accepts a 4 to 20 mA input forvalve positioning. Actuators featurethermal overload protection andpermanently lubricated gear train.
The pneumatic double acting actuator usesan air supply to drive the valve open andclosed. The actuator has two supply ports,with one driving the valve open and theother driving the valve closed. Springreturn pneumatic actuators use the airsupply to open the valve, and internallyloaded springs return the valve to theclosed position. Also available is the SNsolenoid valve to electrically switch the airsupply pressure between the air supplyports for opening and closing the valve.Actuators are constructed of anodized andepoxy coated aluminum for years ofcorrosion free service.
