Product Description

Rupture Disc Circulating Valve For Drill Stem Testing Service


Rupture Disc Circulating valve is the same as RD Safety circulating valve except short of ball valve section, the annulus pressure made Rupture Disc burst and the pressure goes into Rupture Disc hole and push circulating mandrel forward, then open the circulating ports.


The Rupture Disc Circulating valve is composed of three major sections:

1. The power section consists of a power mandrel case and rupture disk that is available for a wide range of pressure applications. The rupture disk bursts at a predetermined pressure, allowing annulus pressure to be applied to a differential area on the power mandrel. The power mandrel moves down, first pushing the ball valve closed, and then opening a set of circulating ports.


2. The circulating section consists of a set of ports that are initially sealed by the power mandrel. When the rupture disk bursts, the power mandrel moves down, exposing the ports that allow communication between the annulus and workstring.
