Features:
- The external-closing structure eliminates the possible damage to the closing sleeve when drilling out accessories.
- The pressure-relief design eliminates fluid trapping and compression which might occur while opening and closing the side ports.
- All accessories are non-rotating and made of easily drillable materials.
- Pump-Down Opening instead of a Free-Fail Opening Plug can be used in a continuous two-stage cementing operation.
