Design Features

The CVS Series 128-PQC Control Valves are suitable for on/off dump valve service in oil & gas production applications; in either sweet or sour gas conditions. These valves are also useful for on/off high pressure control of numerous gases 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. The flow characteristic of the CVS 128PQC is quick opening, with a 45o taper plug.
