1" and 2" valves. Used as Dump Valve or Pressure Regulator. Our Stem Guided valves have smaller trim sizes for smaller valve coefficients (Cv) compared to the Cage Guided series. "Stem-guided" refers to the stem itself guiding the trim into its seat. "Non-balanced" means that the pressure above the trim seat is not counterbalanced by the same pressure below. All valves in this series have the option of emissions-free electric actuation.
