POLOVAL™ Composite Check Valve for High-Flow Cementing.
The POLOVAL™ is a premium composite check valve designed for demanding cementing applications involving high flow rates, abrasive LCM materials, and extended circulation durations. The valve is engineered to deliver reliable sealing performance while maintaining excellent drillability during subsequent operations.
The POLOVAL™ features a fully composite housing and plunger manufactured from high-strength synthetic materials, providing consistent performance under high-temperature and high-pressure conditions. Its non-metallic construction ensures smooth and predictable drill-out with PDC bits, reducing operational risk during post-cementing drilling activities.
The valve design has been validated to meet and exceed the requirements of API 10F, 4th Edition, offering performance margins beyond current industry standards. Multiple valve configurations can be stacked when required, providing flexibility across a wide range of casing sizes and well conditions.
