Grafoil Packing Information
Grafoil is a high temperature packing material that requires a load on thematerial to generate a seal.
In air,Grafoil maximum temperature is 973F(523'ºC),in steam,Grafoilgoes up to to the maximum temperature of 1,200F(648 ºC).Grafoilpacking is not for use with pneumatic actuating valves.
Valve Ratings With NA-LOK End Connections
Valve ratings may be limited to the maximum working pressure ofconnective pipe and tubing.For valve rating with NAl-Lok tubefittingend connections ,refer to NAlLOK catalg providing suggested workingpressures in vaious tubing OO,wall thicknesses,and materiaks
Packing Adjustment And Actuation Torque
Extreme temperature fluctuations while vave in service may requirepacking adjustment.Vales that have not been actuated for a period oftime may have a higher initial actuation torgue.
