Injection Quills with Double Block & Bleed Valve

In most modern applications there is often requirement to take a sample of the process fluid or inject a particular chemical directory into the process stream at full operating pressures and temperatures.

To meet this requirement then any of the YDB VALVES ranges of Double Block Bleed Valve including one piece body DBB, Modular type, Monoflange Valve and Manifold Valve can be fitted with either an Injection Quill or SAMPLING probe whilst retaining the wide choice of options available in each range.

Probes and Quills extend into the process medium and are designed to meet the individual application requirements. Units can be fitted with an Internal Check Valve to prevent back flow into the process stream.

INJECTION QUILLS

In many applications there is a need to inject chemicals such as de-waxing, de-icing or de-foaming agents into the process stream to facilitate a free flow of the process media.

Using the primary and secondary isolation valves the required chemical is injected directly into the process stream. It is usual for injection valves to be fitted with a non-return check valve that only opens when chemicals are injected into the process line thus preventing back flow out of the process stream.
