CV30
The CV30 control valve is a reliable, full-port control valve in a compact package featuring balanced plug control trim for excellent throttling or on/off control of fluids.
The adjustable topworks is designed to save space while leaving enough room to mount a controller. The soft-seat design achieves repeatable bubble-tight shutoff while remaining out of the flow path.
The CV30 is ideally suited for a wide range of applications with pressure control, level control or flow control.
- The valve is available in a variety of material options and trim sizes.
- Metal-to-metal seat is available.
- A NACE option is available for sour service.
