Our Sample valves are suitable for chemicals in liquid and gas states, including many of the 140 chemicals found on OSHA's "List of Highly Hazardous Chemicals, Toxics, and Reactives" as well as chemicals that meet the criteria for ASME B31.3 Category M Fluid Service.
The working principle of our Sampling Systems is very simple: product flows through the valve, and the stem or spindle plugs the outlet. When operators want to collect the sample, they actuate the valve, which retracts the spindle and opens the outlet. The product then flows into the receptacle.
Thanks to our Simple Modular Design, our sample valves are Multifunction and work the same to sample stable liquids or to sample volatile chemicals.
How to guarantee a representative sample?
The product that flows through the valve must be representative. This means the best place to install the inline sample valve is on the process line, or on a bypass or fast loop between the high-pressure and low-pressure sides of the pump. Installing an inline sample valve on a dead leg is not advisable because you will not get a quality sample unless your purge and flush.
Unlike traditional complex Sample Panels and Closed Loop Systems, we have put a lot of effort into developing our Grab Sample Solution to give you a Simple Modular Design that's best-suited to sampling the harshest chemicals.
