DAV MX™ - Standard Diverter Dart
The standard method for DAV MX™ bypass, delivering 100% BHA bypass with in a hold-open mode. The default dart to use unless looking specifically for split flow or full pressure relief.
DAV MX™ - Split Flow Dart
The best method for DAV MX™ hole cleaning, by delivering some flow to the bit also in a hold-open mode. This BHA flow gives cooling for rotation friction in the BHA as the string which is useful for better agitation and string management.
DAV MX™ - Alternative Diverter Dart
Shorter than the Standard Diverter Dart, this dart allows the valve to close with the pumps off, closing off the annulus. Although it makes the valve do more work, it may be preferred in certain situations to keep the annulus shut out when the pumps are off.
DAV MX™ - Universal Closing Dart
Whichever opening dart is used the Universal Closing Dart will shear it out to close the DAV, with both darts landing in the catcher below. It operates with full bore sealing above the opening dart to provide maximum load onto the concentrator button on the lower dart to shear out the pins.
DAV MX™ - Ultra Series
The Ultra Series Dart is capable of high speed activation, allowing it to be pumped in at up to 400gpm which is ideal for ERD (Extended Reach Drilling). It also has a low shear out pressure (600PSI) which makes it the perfect dart for delicate formations or coring runs.
DAV MX™ - Emergency Shut-Off Dart
Not only does the DAV MX™ push the operating envelope further and have the best reliability in class, it also provides a totally unique back-up closing system. Should the valve become damaged by any unexpected events, users can deploy the Emergency Shut-Off Dart (ESD) which patches and seals the leak path but still provides a generous thru-bore allowing operations to continue. The ESD ultimately saves the Operator a trip out of hole.
