Abstract
A cycle valve can include a valve body and a dynamic sealing spool assembly contained within the interior of the valve body. The dynamic sealing spool assembly includes a sleeve and a gate cartridge assembly which slides within the sleeve between an open and a closed position. The sleeve can include a sleeve opening while the gate cartridge assembly can include two openings, each of which includes a dynamic seat assembly. The dynamic seat assembly in one opening can be formed by upper and lower dynamic seats configured as solid blocks which seal the pathway through the valve when the gate cartridge assembly is in the closed position. The dynamic seat assembly in the other opening can be formed by upper and lower dynamic seats configured as cylinders which form the pathway through the valve when the gate cartridge assembly is in the open position.
