Dbb Gate Valve

The dbb eliminates the need for complicated costly multi valve systems while still providing you with zero leakage protection in harsh applications.

Dbb gate valve. This will result in huge space saving and weight which are positive benefits for fpso s and oil platforms. The valves in a dbb valve are attached as either a unit or a manifold inside one compact body. Double block bleed valves a dbb or dib valve can perform the tasks of 3 separate valves knowing 2 separate isolations and 1 drain valve. Double block bleed valves can be supplied according to api6d and api6a.

Bfe double block and bleed valves replace existing tradi tional techniques employed by pipeline engineers to generate a double block and bleed configuration in the pipeline. The block valves are installed on either end while the bleed valve is in the middle. Oubei town wenzhou city zhejiang province china 325105. Posiwell double block bleed dbb gate valves posiwell double block bleed gate valves have been designed by engineers with over three decades of experience at the forefront of valve service repair modifications and automation and a deep understanding of the root causes of db b valve failures.

The cameron general valve twin seal double block and bleed dbb plug valve reduces this constant wear by using two seating slips mounted independently on a tapered plug by dovetails which mechanically retract from the seating surface prior to rotating. It then uses the bleed valve to drain the excess medium. As per api 6d a double block and bleed ball valve is a single valve with two seating surfaces each of which in the closed position provides a seal against pressure from both ends of the valve with a means of venting or bleeding the cavity between the seating surfaces. The dbb valve works by isolating the onstream flow of fluid or gas from either end of a pipeline.

According to api a dbb valve is a single valve with two seating surfaces that in the closed position provides a seal against pressure from both ends of the valve with a means of venting bleeding the cavity between the seating surfaces. The dss double block and bleed dbb valve provides the isolation you need when you need it. Dbb and dib definitions the most basic thing a user is looking for when they specify a double block and bleed valve is a compact valve or valve system that provides more reliable isolation in critical areas than a standard single valve would.
