Description
Series WE35 3-Way NPT Brass Ball Valve
Full Port, Electric or Pneumatic Actuators
DWYER Series WE35 Brass Ball Valve incorporates a full port 3-way brass ball valve for great flow rates with minimal pressure drop. The DWYER Series WE35 Brass Ball Valve features a blowout proof stem for added safety, reinforced PTFE seats and seals for longer life, and a brass ball for better performance. Actuators are direct mounted creating a compact assembly for tight spaces. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages, and two-position or modulating control. Actuators feature thermal overload protection and permanently lubricated gear train.
The pneumatic double acting actuator uses an air supply to drive the valve open and closed. Spring return pneumatic actuators use the air supply to open the valve and internally loaded springs return the valve to the closed position. Actuators are constructed of anodized and epoxy coated aluminum for years of corrosion free service.
