3 7/8" x 15K psi OMNI valve Multicycle Circulating Valve/

Repetitious Circulating valve

Repetitious Circulating Valve consists of Nitrogen section, oil section, Circulating valve section and a Ball valve section.

The repetitous circulating valve is also called Multicycle circulating valve and OMNI circulating valve,it is a full opening, annulus pressure-operated re-closable circulating valve which can be open and closed many times. The tool is operated by repeatedly cycling the annulus pressure up to a predetermined value and then releasing this pressure.

OMIN Vale is acceptable for the full-opening formation testing in cased hole, oil tube tradition perforation, tube string testing and cycle operation in the conjunction of perforation and full-opening formation testing. It overcomes the shortcomings of some other circulating valve, at a certain position, can use the annulus pressure to operate other tools many times and there is no influence upon the OMNI circulating valve.
