OPERATING LIMITS: d 1 = 10 ÷ 100 mm p= 10 kg/cm ² v= 20 m/s t= -20÷ +200oC ( *) ( * ) The temperature resistance depends on the material of the secondary seals used. The operating limits are defined by the PV factor which is determined for the sealing system characteristics and those of the application. DESCRIPTION: A general-purpose single, robust seal in which the contact surfaces can be exchanged with each other. It can be used in industrial applications for clean fluids with low viscosities or with a low content of suspended solids that tend to produced sediments or adhere to the seal. Types: FH6: secondary seals made of PTFE. FHC: same structure as FH but the length is I3C.
