Description
Series WE06 3-Piece NPT Stainless Steel V-Ball Valve
V-Port, Vented Ball, Electric or Pneumatic Actuators
DWYER Series WE06 Stainless Steel V-Ball Valve incorporates a V-port ball valve for impressive flow rates with minimal pressure drop. The 60° and 90° balls offer an equal percentage flow characteristic. W. E. Actuators are directly mounted creating a compact assembly for tight spaces. Limit switches can be mounted directly to the valves allowing for remote position indication.
The DWYER Series WE06 Stainless Steel V-Ball Valve can be configured with an electric or pneumatic actuator. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages and two-position modulating control. Actuators feature thermal overload protection and a permanently lubricated gear train. The pneumatic double acting actuator uses an air supply to drive the valve open and closed. The actuator has two supply ports with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve and internally loaded springs return the valve to the closed position. Also available is the SV3 solenoid valve to electrically switch the air supply pressure between the air supply ports for opening and closing the valve. Actuators are constructed of anodized and epoxy coated aluminum for years of corrosion free service.
