Class IV per ANSI/FCI 70‐2 and IEC 60534‐4, (0.01% of
valve capacity at full travel), for either flow direction
Flow Characteristic
Approximately equal percentage
Flow Direction
J
Forward (normal) flow is into the convex side of
the V‐notch ball
J
Bidirectional flow is into either side of the V‐notch
ball

With diaphragm or piston rotary actuator,
field‐reversible between
J
push‐down‐to‐close
(extending actuator rod closes valve body) and
J
push‐down‐to‐open (extending actuator rod
opens valve body)
Shaft Diameters
(2)
and Approximate Weights
See table 3
1. The pressure/temperature limits in this manual and any applicable standard limitations should not be exceeded.
2. Shaft diameter and spline end must match available shaft diameter of actuator.
