i-Quip HN-Series

Chemical Injection System


TCO Chemical Injection Systems are based on the high end I-Quip Technology Chemical Injection Devices. The first purpose built injection check valve was developed in 2001 and since then has been a benchmark standard installed for multiple operators globally.

H-Series


ISO 14310 V0 qualified. The HN-Series represents the conventional series with a broad range of configurations. From a single compact barrier check valve to a modular dual or triple in line ISO 14310 V0 barrier qualified check valve system with preinstalled HX Type modular rupture cartridge. The main purpose of the HN-Series valves is to create your primary seal between the production tubing and the control line system. Supplying the chemicals for downhole chemical dosage and treatment.


Externally testable. All Devices carry the option of being equipped with an externally testable hydraulic control line connection. The HN-Series device is designed for permanent installation into the TCO range of chemical injection mandrels.

The HN-Series Barrier Qualified Injection check represents the highest level of integrity and is the first ever device purpose built for downhole chemical injection. Having over a decade in successful service the HN-series barrier is at the core barrier of all of the TCO special devices used for various injection applications.
