Key valve specifications and benefits
NEMA 4 housing with manual cover and handwheel.
Self-locking gear train and reverse motor.
Multiple voltages available.
Support shaft seal: the adhesion of the elastomer to the phenolic support ring prevents deformation, which is a common cause of shaft leakage.
Wide flange face seal area provides tight flange - valve seal eliminates the need for flange washers.
One-piece 416 stainless steel stem shaft for reliability and positive disk positioning.
Position the holes in the bottom and top of the Wafer Valve Ease installation. 
Precision profile plates provide a hermetic closure for minimum torque and longer seat life.
Precision tapered pin ensures positive anti-vibration shaft and disc connection.
One-piece 416 stainless steel stem shaft for reliability and positive disk positioning.
Four bushings provide shaft support for positive shaft centering and actuator support.
