DST Tools 5" OMNI Valve 

Product Introduction

The Repetitious circulating valve (OMNI Valve) is an annulus pressure operated, reclosable circulating valve.

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.

OMNI valve consists of a nitrogen section, an oil system, a circulating valve, and a ball valve. The operating and control mechanisms are contained in a closed oil system activated by annulus pressure acting on the nitrogen chamber. The circulating valve and the ball valve work together to keep circulating pressure off the formation.
