Grafoil is a high temperature packing material that requires a load on
the material to generate a seal.
In air, Grafoil maximum temperature is 973°F (523°C), in steam, Grafoil
goes up to themaximum temperature of 1,200°F (648° C). Grafoil packing
is not for use with pneumatic actuating valves.
Valve with standard globe and ball disc is designed for use in a fully open
or fully closed position.
Refer to Cv in the ordering information and dimensions table on Page 2.
Valves for use in sour gas are available. Valve wetted components are selected to the requirements of NACE MR0175 for
sulfide stress cracking resistant materials. To order, insert -SG in the basic ordering number.
SS316 bar handle is standard. Optional anodized black
aluminumbar handle is available.
To order valve with factory-assembled optional aluminum
handle, insert designator -AH in the ordering number.
To order handle for field assembly, select desired handle
ordering number from the table.

Valve ratings may be limited to the maximum working pressure of
connective pipe and tubing. For valve rating with DK-Lok tube fitting
end connections, refer to DK-Lok catalog providing suggested working
pressures in various tubing OD, wall thicknesses, and materials.
Valve flow may be reduced by the restriction of pipe and tubing
connected.
Extreme temperature fluctuations while valve in service may require
packing adjustment. Valves that have not been actuated for a period of
time may have a higher initial actuation torque.
