SPECIFICATIONS
Table-1 Model Chart.
Temperature Restrictions
Verify that the fluid temperature of the media in the valve versus the ambient temperature at
the actuator does not exceed the ratings shown in Table-1.
Table-2 Restrictions on Maximum Ambient Temperature for Actuators.
Close-off Pressure Rating
Close-off pressure ratings are listed in Table-2 and Table-3. Check the appropriate table to
verify that the selected valve, valve linkage, and actuator provide adequate close-off
pressure for your application.
Required
Components
The actuator, valve, and valve linkage should be purchased separately. See Table-2 and
Table-3 for selections.
INSTALLATION
Inspection Inspect the package for damage. If damaged, notify the appropriate carrier immediately.
If undamaged, open the package and inspect the device for obvious damage. Return
damaged products.
Requirements Tools (not provided):
Appropriate wrenches for stem extensions, lock nuts, packing nuts, and brackets
Appropriate screwdriver for actuator mounting screws
TOOL-37, 1-5/8" open-ended wrench with a maximum thickness of 3/16"
Training: Installer must be a qualified, experienced technician
Caution:
Avoid locations where excessive moisture, corrosive fumes, or vibration is present.
Install all two-way valves so that they close against the flow. An arrow on the valve body
or a tag indicates the proper flow direction.
Always install three-way mixing valves with two inlets and one outlet.
Always install three-way diverting valves with one inlet and two outlets.
The actuators can be mounted in any position above the centerline of the valve body.
For steam applications where the ambient temperature approaches the limit of the
actuator, the valve stem should be mounted 45° from vertical. When selecting a
location, allow sufficient room for accessories and for service of the product.
