FAQs on Sampling Cylinder and guide for Purchasing Sample Cylinders with Needle Valve.

What are sampling Cylinders with Needle Valves used for?

They are used to facilitate storage, evaluation and movement of liquid and gas under high pressure or high temperature.

Can FAV Sampling Cylinders be used with Natural Gas?

Yes they are safe and tested to be used with Natural gas or any other gaseous medium at high pressure and high temperature

Are FAV Sampling Cylinders tested?

We perform hydro pressure proof testing with water as a medium. 100 % sample testing is undertaken.

What is the use for Needle Valves in this type of Sample Cylinders?

Since it has medium at a constant pressure, most common accessories are Needle Valve (for control). Needle Valve helps the pressure intact in the cylinders.

When are Flat end Cylinders preferred in this configuration?

Very rarely

When to use single ended cylinder over double ended cylinder?

There is no general rule for above, but single end cylinder is more common when sole purpose is storage. While Double ended cylinders are used when it’s part of sampling system, instrumentation line or pre-installed in sampling cabinet. Basically it acts as pre-instrument device.

Does FAV give option of installing the Cylinders in Sampling Cabinet?

Yes we do give mounting clips or hose cir-clips for attached it on the panel .This configuration is very popular in the sampling system. One of the most common Valves used with Sampling cylinder is Needle Valves
