Description
The Dual Flapper Check Valve is a device used to prevent pressure or fluid from passing up through the
assembly. It is used in conjunction with a “TICX” or “TICR” Locking Mandrel.
The Dual Flapper Check
Valve has two flapper assemblies with seals to prevent pressure of fluid bypass upwards.
The Dual Flapper Check Valve is a back pressure valve that allows the operator to pump through the assembly while allowing maximum flow through the assembly with minimal restriction.
Equalization can be achieved by placing an equalizing sub above the assembly, or by running a prong
attached to the pulling tool that will knock both flappers off seat..
