The V5051 series advantage lies in its ability to
perform like a globe valve while achieving high close-
off pressures with a single spring return actuator. This
premium valve delivers a high close-off using a single
spring return actuator on all valves up to 6". It is highly
suitable for medium-pressure steam applications.
