Description
CAMTOP Reclosable Circulating Sleeve Valve | 10K PSI | DST Service
5 inch (127.5 mm)
Product Overview
The CAMTOP Reclosable Circulating Sleeve is assembled as part of the tubing string to establish communication between the tubing string and the casing annulus for single or multiple-tubing string completions.
The reclosable circulating sleeve is annulus pressure operated without the use of a wireline or coiled tubing tools. It features an internal sliding sleeve which seals against the circulating ports. The sleeve is held in place with shear pins; by applying a predetermined pressure to the annulus, the shear pins shear and the differential pressure shifts the sleeve to open the circulation ports.
A spring mechanism is equipped to close the circulating sleeve once the annulus pressure is released, using spring force to return the sleeve to the closed position. This allows multiple open-close cycles during a single trip.
