Circulating One Way Washdown Valve and Washdown Assemblies
The wash-down valve is used to allow water to flow out of the bottom of the screen assembly. This valve allows the well to be effectively rinsed-out and, in the case of a gravel pack, ensures that the filter pack is effectively placed. The wash-down valve can also be used to circulate the screen assembly into the correct position.
Variperm’s washdown valve relies on a floating ball to seal the valve. The complete valve assembly is made from stainless steel and comes with a standard 2” NPT pin connection.
Variperm’s washdown assemblies are custom made, to attach to the bottom of the screen assembly. They contain a Left-hand Running thread and are used in conjunction with a Left-hand thread x Right Hand thread running tool to attach to the working String. The assembly is completed with a washdown valve and fishtail spade bottom.
