– Fossil-fuelled power stations
– Petrochemical industry
– Pipelines and tank farms
– Refinery
– Process engineering -
Advantages
– Long service life and high functional reliability
- – Two-piece self-aligning gland ensures even compression of packing rings.
– Inconel-reinforced braided packing end rings offer smooth wiping action and prevent extrusion of graphite.
– Stellite 6 hard-faced body seat ensures high wear resistance.
– Burnished stem and smooth stuffing box surfaces extend the service life of the gland packing.
– Low actuating torque due to rolling element bearing.
– Stop nut prevents jamming of the wedge assembly in the seat.– Additional features ensure safe sealing to atmosphere:
- – Additional safety and blow-out protection by standard back seat.
– Die-formed endless graphite packing rings reliably seal the stem passage.– Reliable, tight shut-off
- – Perfect contact at seat/wedge interface ensures tight shut-off.
– Self-aligning split wedge ensures tight shut-off.
– Streamlined flow path minimises pressure losses.– Tie rods replacing traditional yoke ensure easy assembly and maintainance (only for Class 3100 and 3600)
