Process Injection Valves

You can count on Colson’s over 20 years of experience in the production of valves for the oil, gas and petrochemical industry for dependable process injection valves that are engineered to provide years of value and service. Our process injection valves are designed with a variety of nozzles to work in just about any new or currently existing project.

These valves are created to seamlessly inject chemicals or other media perfectly into the process stream simply and easily. These valves are available in single or double flange connections, screwed connections and in N-Type double block and bleed.

The valves offer significant savings in both weight and space as well as reducing installation time and cost. Suitable for isolation of lines, Sampling or chemical injection service the valves can be supplied using ball, Outside Screw and Yoke (OSY), bolted or threaded bonnet needle valves.

Connections can be manufactured that include flanged, threaded, hubbed, compression or welded and are available in single piece or bolted construction.

Also using a standard DBB valve design the chemical injection valve allows the safe injection of chemicals into the process line at full pressure.

The probe usually features a 3mm (1/8″) hole or spray nozzle allowing the injection to be dispersed into the process evenly. A check valve on the inlet prevents any back flow out of the process stream.
