Considering purchasing a CRT Mud Saver?

Volant’s MSV adapts to the Casing Running Tool with either internal grip (CRTiTM) or external grip (CRTeTM) architecture. The MSViTM is designed for internal grip and MSVeTM  for external grip tools. Installed between CRT and casing seal, the MSV is designed to entirely stop fluid flow after fluid circulating or casing running operations. The valve opens with applied pressure when circulating begins and closes when it is stopped. The MSV allows back flow and will not trap pressure in the casing string.

The MSV has been designed to the same flow rate limit of each corresponding CRTi and CRTe3.
