One of the most critical operations in pigging is opening the closure that provides access to the pig trap during launch and recovery operations. When the closure door is opened during the insertion or removal of a pig or other tool, there is a risk of explosive gas-air mixture.

The industry’s most trusted closure for 20 years, the D2000 quick-actuating closure combines operator safety with ease of operation. After depressurization, opening and closing operations are performed in a fast, single motion, with the operator standing safely to the side. Thus, the D2000 closure maximizes efficiency and reduces both, personal operator risk and company operational cost.

The ProSeries™ Advantage means the D2000 closure meets more specifications and codes standard, and lead time is shorter, too.
