8532 Valve

Valve Orientation

The valve can be installed in any orientation, however it is recommended that the valve drive shaft be horizontal and
the actuator vertical as shown in figure 4.

Install the valve with the high‐pressure shutoff side in the direction noted by the flow arrow for proper installation, and
see figure 4 for more information.

Before Installing the Valve

  WARNING

The edges of a rotating valve disk (key 2, figure 9 or 10) close with a shearing, cutting motion. To avoid personal injury,
keep hands, tools, and other objects away from the disk while stroking the valve.

If the 8532 valve is equipped with a fail‐open actuator, cycle the valve into the fully closed position. Ensure the valve cannot
open during installation by using travel stops, a manual actuator, a constant supply pressure to the pneumatic actuator, or
other steps as necessary.
