The Series WE04 incorporates a full port2-piece flanged 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 WE04 can be configured witheither a pneumatic or electric 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 closed, while the modulatingactuator accepts a 4 to 20 mA input for valvepositioning. Actuators feature thermaloverload protection and permanentlylubricated 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 the closedposition. Also available is the SN solenoidvalve to electrically switch the air supplypressure between the air supply ports foropening and closing the valve. Actuators areconstructed of anodized and epoxy coatedaluminum for years of corrosion freeservice.
