Series 4260 - Cast Iron Cement Retainer
Compact, and dependable, the Cast Cement Retainer is easily set via wireline or pipe. Setting force is maintained by a Ratcheting Lock Ring on top of the cement retainer. On tubing models (< 4-1/2”), the cement valve is a molded poppet seal. Poppet Seals hold from below after the pumping pressure is reduced. On casing models (≥ 4-1/2”), the cement valve uses a balanced sliding sleeve. The balanced sleeve seals from both directions.
Features/Benefits
- Rotationally locked for easy drillout.
- Balanced Seal Valve provides protection against re-opening.
