Having a combined function of GTD and MTD, the FSD gives
a tight shut-off at nominal pressure and temperature rating.

FSD sealing system consists of reinforced teflon and metal seat.
Although FSD has double seat structure, it requires relatively
low operating torque.
FSD valve works with the metal seat when a teflon seat has been burned out.
FSD provides the more reliability for steam and hot air line among its applications.
