  • Stainless steel stem with rolled threads for high strength
  • OS&Y stem arrangement gives from a distance a clear, visual indication of the valve's open/close state
  • Stuffing box for re-tightening with three main O-rings, and two NBR O-rings in a polyamide gland bushing
  • Handwheel
  • Bonnet gasket in EPDM with a circular cross-section and fixed in a recess to avoid blow-out
  • Counterbored bonnet bolts in zinc coated 8.8 steel, sealed with hot-melt and encircled by the bonnet gasket
