  • Notes:
    A. Permissible, but not recommended for prolonged usage above 800ºF
     

  • B. These values may be interpolated on a linear scale for shut-off pressures between 740 psi and 1480 psi.
     

  • C. Values shown are for preferred direction of shut-off under static differential pressure conditions.
