Dual Circulating Valve




The Taylor Made  Dual Circulating Valve provides a means of emergency circulation through rupture discs and a ball operated circulating feature. The rupture discs provide a means of circulating if the BHA become plugged. Applied internal pressure exceeding the burst rating of the disc will cause the discs to rupture and open circulation to the annular area. The ball operated valve shifts open when a ball is dropped to the tool and pressure is applied to exceed the pre determined shear value of the valve. Once shifted, required, the rupture discs can be removed and replaced with plugs.
