133 Series Self-Operated Regulators
Features
  •  Wide Pressure Range Capability with Single
    Regulator—Type 133H may also use Type 133L
   springs, allowing pressure settings to be varied
   between 2-inches w.c. and 10 psig (5 mbar and
   0,69 bar) by changing springs.
  •  Types 133L, 133H and 133HP Suitable for
    Monitoring Applications—O-ring stem seal on
   Types 133L, 133H and 133HP isolates body
   pressure from controlled pressure.
  •  Excellent Shock Characteristics and Fast
    Speed of Response—Due to two-way stabilizer
   vent valve, which vents the spring case more
   rapidly than conventional vents, lag in diaphragm
   and valve disk movement is minimized.

  •  Bubble-Tight Shutoff—Single-port construction,
   large diaphragm area, and light-rate springs along
   with disk material and seat design provide low
   lock-up pressures.
  •  Spring and Diaphragm Effects Minimized
    boosting system provides excellent performance
    over a wide range of flow conditions.
  •  No Seat-to-Seat Adjustment Required—Balanced
   single-port design eliminates necessity for seat-to
   seat adjustments to achieve bubble tight shutoff.
  •  Easy Access to Trim Parts—Valve seat, disk, and
   cage easily removed with body remaining in line
    and without disassembly of actuator portion; orifice
   is not threaded in.
  •  Reusable Pressure Seals—O-rings used for
   pressure seals, unlike gaskets, are not ordinarily
   damaged by disassembling the regulator.
  •  Resistance to Piping Stresses—Steel
   constructions are available to help resist pipe stresses.
