Mud Saver Valve

The Wenzel Mud Saver Valve is a normally closed valve placed at the bottom of the kelly or top drive which automatically opens when circulation pressure exceeds approximately 65 psi (450 kPa). The mud saver valve closes when circulation is stopped, retaining the mud inside the kelly or top drive to minimize spillage and mud waste.

Features:

• Replaces the kelly saver sub
• Opens in both directions at minimal pressure
• Automatic operation
• Does not contain seats or mud ports, eliminating expensive chargeback's common with other mud saver designs.
• Straight through bore while circulating
• Minimal pressure loss
• Reduce wear and tear on kelly valve
• Avoid potential error of leaving kelly valve closed
• External bronze or elastomer casing saver sleeve
