  • Solid CoCr alloy wedge (optional) ensures low friction and long service life.
  • For Class 1500 valves and for steam service, seats are seal-welded to the body.
  • Packing rings are precompressed to 4000 psi to provide a high integrity seal.
  • For welded bonnet valves, the bonnet is threaded in and torqued to an engineered torque value and the body bonnet joint is strength-welded, offering double protection against leakage. (Body/bonnet threads and strength-weld).
  • Fully guided wedge reduces wear on seating surfaces.
