Pressure Actuated Cementing Valve
Ensure reliable second-stage cement placement and effective annular isolation with the pressure-actuated cementing (PAC) valve from Baker Hughes. A hydraulically operated stage cementing valve, the PAC valve provides circulating ports between the inside of your casing or liner and the annulus. The valve’s simple design ensures an easy method of opening and closing by blanking the casing or liner at some point below the valve.
You can confidently run the PAC valve anywhere in the liner casing and with any Baker Hughes inflatable external casing packer (ECP) in your vertical, horizontal, and deviated wellbores. Once the ECP is set, the PAC valve is opened by blanking off the opening sleeve shear screws and shifting the opening sleeves down. This opens a communication pathway between the valve’s inside diameter (ID) and your well annulus. After pumping the cement slurry, a wiper closing plug lands in and closes the PAC valve, resulting in full casing integrity. The wiper closing plug is designed with an anti-rotation feature, allowing easy drill-out of the plug and seat.
