AutoValve™ MudSaver Valve

Eliminates back pressure and leaking

As the only “full-opening” mud saver valve available in the drilling industry, the patented AutoValve MudSaver Valve ensures positive valve operation and allows high flow rates while eliminating erosion and leaking that can hinder the performance of spring-type fill-up valves. This Valve automatically opens when inserted into the casing and automatically closes when it is removed. It also prevents surging the well and is immune to LCM (Lost Circulation Material) solids. When the AutoValve is inserted in the casing, it can handle Fill-up, Flow-Back & Circulating procedures at any time.

Additional Advantages

  • No separate circulation valve required
  • Handles very large volumes of fluids when filling, circulating or flowing back
  • Eliminates pressure on the stand pipe
