High Pressure Stem Guided Non-Balanced Control Valves
Kimray High Pressure Stem Guided Non-Balanced Control Valves
These 1” and 2” high pressure, stem guided, non-balanced control valves can be used as a dump valve or pressure regulator. In this instance, “stem-guided” refers to the stem itself guiding the trim into its seat and “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.
All of Kimray’s stem guided valves have smaller trim sizes for smaller valve coefficients (Cv) when compared to the cage guided series.
