Sub-drill DSV Test Stand, Drill Stem Valve

Another Sub-drill DSV™ Drill Stem and Top Drive Valve Test Stand ready for delivery to our Global Client base

Since introduction in 2003, the Sub-drill DSV™ test stand has become the test stand of choice worldwide for clients looking for a field proven solution to help minimise time and cost while meeting well control equipment testing compliance for testing of Top Drive and Drill Stem valves.

Drill stem valves facilitate safe well control and are a critical part of the safe operation of the drill stem; testing these products is vital to the operational integrity of the drill stem. The DSV™ Test Stand provides a quick, easy, pre-defined and safe method of testing top drive and drill stem valves before installation in the string, without requiring the use of Rotary Table, Rig Tongs or Iron Roughneck. 

Sub-drill continue to invest in all of our products and respond to client feedback with innovative solutions. Some recent feedback from a client led us to enhance our top seal design to increase low-torque performance for ease of use by rig personnel, and also by offering a pressure relief valve system, supplied as standard to new units or retrofitted to existing units where required.
