The CVS Series 128PQC Control Valve body assembly is suitable for on-off dump valve service in oil and gas production applications, in either sweet or sour gas conditions. This valve is also useful for on-off high-pressure control of numerous gasses and liquids, and can be used with materials that are viscous or erosive.
This is a single port valve with unbalanced stem-guided valve plug, and push- down-to-close valve plug action. Operated by a Type 128 spring-and-diaphragm actuator, the assembly can be operated in a normally open or normally closed application. This setting can be reversed in the field with minimum disruption and no additional parts.
