Dual circulation valve

1.     Introduction

Dual circulation valve has dual functions of cutting pin and rupture disc. The valve can circulate by break the rupture disc and provide adequate circulation channels to pump  the ball, or drop ball , pressure to shear pins and achieve maximum cycle. Dual circulation valve is applicable to all sizes of coiled tubing operations and can also change rupture disk into screw plug.
