The Pragma Type N Standing Valve is a wireline retrievable packoff device designed to land onto no-go type landing nipples. Whilst landed in the nipple profile the standing valve will hold pressure from above but can also allow the well to flow.

Pragma can design the valve to suit any no-go nipple profile. It can be run on slickline using any generic running tool which can either be left in place for well testing for single run deployment and retrieval of released and left in place.

It is designed for prolonged flow wear and is simple to redress. A shear sleeve pressure equalizing feature permits easy retrieval from the well.

The Pragma Type N Standing Valve is commonly used for testing completion tubing. It can also be used be used for setting packers or in gas wells where fluid retention is required in the tubing string.
