Drillmax - Model DrillmaxPro 10K F -Plunger Type Valve

Allows constant fluid flow while drilling, yet provides a positive instantaneous shut-off if the flow is stopped or reversed. The closed valve prevents back flow when drilling stops or when breaking connections, and keeps cuttings from clogging the bit. The float valve also acts to assist Blow Out Prevention (BOP) equipment to maintain control over pressure in the well.
