Description
The Slurry Vee‐Ball valve shown in figure 1 mates with CL150 or CL300 raised face flanges. Rugged construction, highly
wear‐resistant trim materials, and an unrestricted straight through flow path make the design ideal for controlling the
most abrasive of slurries.
A shaft with a choice of drive connections will allow a variety of power operated actuators and valve positioners or
controllers to be used.
The design is particularly effective in minimizing erosive damage to the adjoining pipework, thereby providing greater
operational safety and service life when compared with other valve types.

Valve Installation
Shaft axis shall be horizontal
Actuator Mounting
Right‐hand or left‐hand, as viewed from upstream
end of valve
Maximum Ball Rotation
90 degrees
Valve/Actuator Action
Standard ball rotation is clockwise (CW) to close with
right hand mount actuator. Left hand mount actuator
with counterclockwise (CCW) to close ball action is
optional. For horizontal pipe run and horizontal shaft
orientation, it is recommended the ball rotate to the
top of valve body upon opening.
With diaphragm or piston rotary actuator and splined
shaft, the valve is field‐reversible between
push‐down‐to‐close or push‐down‐to‐open: J PDTC
(extending actuator rod closes valve) and J PDTO
(extending actuator rod opens valve)
