The 340 Float Shoe is used to bump cement wiper plugs and provide an additional barrier against U-tubing, allowing for contaminated cement to be trapped within casing. The 350 Series Float Collar’s optimized spring force allows the dart to seat on a protective retainer cup while flowing, and ensures sealing even in low pressure and horizontal well conditions.
All valves have HNBR coated Phenolic plungers for good wear resistance and optimum sealing of the valve. The HFX family of valves can be stacked when dual-valve configurations are required and have been tested to API Specification 10F.
