The Hydrostatically Closed Circulation Valve (HCCV) is a hydrostatically operated circulation device. It has a compact design and will close with different pre-set pressures. The sleeve will then be locked in a closed position.
The HCCV reduces the number of intervention runs by eliminating the need for installing a plug to seal off the circulation ports. The HCCV is a patented product.
