Screw downhole motor valves

Bypass valves for Screw downhole motors

 

are designed to ensure that flushing fluid is drained from drilling pipes as drilling string along with screw downhole motor are lifted as well as to fill drilling strings (as they are lowered) with working fluids - water and drilling mud.
