Inside Blow Out
Prevention Valves

Hi-Kalibre Inside Blow Out Prevention (IBOP) valves are a dart type IBOP used to control or prevent back flow or blow out when the Drill Stem Safety Valve (DSSV) is disconnected from the drill pipe. These valves feature a unique one piece body incorporating our patented upper seat and lock ring design. The one piece body provides strength with the minimum possible stack height, while eliminating cumbersome torque body connections. In turn this makes our valves completely field serviceable.

Design features include:

One piece body incorporating our patented upper seat and split ring.
Field serviceable valve, as valve assembly or disassembly does not require making or breaking a high torque connection.
Durable urethane low pressure seal backed by high pressure metal to metal seal, spring energized to ensure positive sealing in any condition.
Complete range of tools for relieving pressure during decommissioning.
NACE trim.
Available in a wide variety of sizes and end connections.
Reliable, field proven, serviceable design.
