Packardís Drop-in Check Valve (DICV) is used to provide protection from backflow during periods when the drill string is left open or kicks are frequent. The landing sub is installed just above the bit sub. The valve may either be installed with the landing sub or placed in the drill string at the top and pumped down to the landing sub. Once seated it allows downward mudflow only.
Features and Benefits
The Packard International DICV is manufactured and tested in accordance with API Specification 7-1 with NACE MR0175 compliant internal components. The retrieval tool is attached to a wireline and locks into place when it is lowered to the valve.
The Packard International DICV can be supplied with any API connection, including many proprietary threads supplied by licensed vendors and OEMs.
High and Low Pressure Sealing
High and low pressure sealing is assured by the unique elastomer and metal-to-metal sealing systems. The DICV is available in pressure ratings up to 15,000 psi working pressure (22,500 psi test pressure).
Packard Internationalís drop-in check valves are designed for even the harshest drilling conditions; however, it is suggested that parts most subject to wear and tear be replaced regularly.
