The Stem-Guided High Pressure Control Valve is a non-balanced valve that can be used as a dump valve, pressure regulator, suction controller, recirculation valve, as well as in plunger lift or flowback applications.

The Stem-Guided Control Valve has smaller trim sizes (available in 1" and 2" end connections) for smaller valve coefficients (Cv) compared to the Cage-Guided series. "Stem-guided" refers to the stem itself guiding the trim into its seat.

It can be fitted with optional electric actuation or operated with compressed air for zero-emission requirements.
