What is the D-2000 Closure System?A launcher and receiver closure system built for speed and ease of use by a single operator, the D-2000 is the reliable solution for small (4-inch) to large-diameter (48-inch and above) applications, with an innovative O-ring design that provides positive sealing and a pressure warning lock for added safety.

What makes it a system?The D-2000 Quick Closure System is more than just a closure. It is composed of three major parts. First, the physical closure. Second, the Field Maintenance Kit. This portable and convenient kit includes all of the necessary O-rings, tools and lubricants to quickly and easily execute O-ring replacement in the field. It also helps ensure an overall reduction in downtime. Third, extensive customer training.

What kind of training is provided?TDW ensures that its customers have multi-format training, including hands-on experience operating the closure in the field. It brings its customers up to an expert level of competency, removing confusion and fear, while greatly increasing safety. Additional training is provided for the maintenance of the

closure, ensuring maximum return on investment by significantly extending the life

of the closure.

Is it actually safer?The D-2000 closure is equipped with a pressure warning

lock, in accordance with UG-35 of ASME Sect. VIII, Div. 1, to alert the operator to the existence of internal pressure prior to opening the closure. In addition, the clamp cannot be opened without completely removing the pressure warning lock screw. Conversely, the clamp must be fully closed in order for the pressure warning lock screw to be inserted through the aligned holes in the locking bars and threaded into the bushing. Lastly, because the design intentionally places the operator to the side when opening and closing the pressure warning lock, clamp ring and door, the D-2000 is safer to operate than closures that require the operator to stand in front of the door.

How does it seal?The large, cross-sectional diameter O-ring, located on the periphery of the D-2000 closure’s barrel collar, provides positive sealing, as well as protection from damage by tools, pigs or debris.
