Globe valve to ANSI/ASME with flanged or butt weld ends, bolted bonnet, outside screw and yoke. Rising stem, Stellite hard-faced seat/disc interface made of 13 % chrome steel, with graphite gasket and gland packing, available in carbon steel, low-alloy steel and stainless steel.
Benefits
- 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).
- Enhanced 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.
