Benefits
- Stem with burnished shank for long service life and high functional reliability of the gland packing
- Hard-faced body seat and solid sealing surface of flexible wedge made of wear-resistant and corrosion-proof materials for reliable sealing and longer service life.
- Two-piece self-aligning gland follower ensures even compression of packing rings.
- Packing end rings of the graphite gland packing enable higher compressive force by gland follower and prevent extrusion of middle graphite packing rings.
- Serrated bonnet gasket fully confined to prevent creep, for reliable sealing
- (Class 150: flat body/bonnet interface due to square or oval flange design to comply with limited face-to-face length specified by design standard).
- Additional safety and blow-out protection by standard back seat.
- Stem nut free from non-ferrous metals, for versatile application.
- Extended maintenance-free service life
- Hard-facing applied to valve disc and seat rings by deposit welding provides extra wear allowance.
- Integral seating surface
