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.
– Hard-faced body seat made of wear-resistant and corrosion-resistant 13 % chrome steel or Stellite.
– Burnished stem and smooth stuffing box surfaces extend the service life of the gland packing.
– Low actuating torque due to rolling element bearing on sizes 6 to 12 inches (Class 600).– Additional features ensure safe sealing to atmosphere:
- – Additional safety and blow-out protection by standard back seat.
– Fully confined cover gasket with controlled compression ensures leak-proof joint.
– Die-formed endless graphite packing rings reliably seal the stem passage.– Reliable, tight shut-off
- – High-grade surface finish: lapped seat/wedge interface
– Flexible wedge for perfectly tight shut-off
– Wedging action ensures tight shut-off at both low and high differential pressures.
– ‘T’-head joint across the flow path prevents wedge dislocation caused by the fluid handled.– Economic benefits
- – Streamlined flow path minimises pressure losses.
– Stem nut free from non-ferrous metals, for versatile application. -
