Sampling Valve

The original Piston Valve – non-clogging and dead-space-free!

Sampling Valves are valves dedicated to drawing a live sample from process piping. They can also inject a substance into a process. Sample valves are frequently used in many industrial processes involving liquids and gases to extract a sample, facilitate quantitative analysis at various stages of that process, and ensure the product quality meets standards. Industries such as pharmaceuticals, petrochemicals, and food processing often rely on our sampling valves for their quality control processes.

Our Sample Valves eliminate the pitfalls of typical sample extraction methods. They extract fluid directly from the pipeline, safely capturing live product samples without failure under pressure or high vacuum conditions and without interrupting the process. They provide true live product sampling for batch production.  

An inefficient and unsafe method for taking samples includes using an open container or a ball valve to fill an open container. This method adds the dangerous possibility of product surplus and spills that can harm and impose health risks on the operator. Using a ball valve for drawing live samples can lead to spills and splashing due to the valve's quick opening 1/4-turn nature. Ball valves also allow for dead space and clogging, which may leave old or contaminated liquid behind, resulting in a bad sample.

Our piston valves are not only safe but also highly efficient in collecting the product sample. They eliminate concerns about process solidification in the valve, providing a pure sample every time. With four series to choose from: Soft-seated, Metal-Seated, Quick Sample, and Quick Advance, we ensure that our valves meet your specific needs. We also offer numerous accessories, like our Live Sample Extraction Containers, for enhanced safety and functionality. 

Soft Seated SV series

The original Piston Valve, our Soft Seated SV series, offers a range of end connections for easy installation: Sample Valve with NPT connection, Sample Valve with Flange connection, and Sample Valve with Insert connection. All have a non-clogging design (no dead space) and an opening indicator for safe user extraction. The Soft Seated SV series provides a reliable live sample as the one-piece piston fills the valve cavity. It is not just for sampling and injection applications, but can also be customized to meet the unique needs of your entire facility, empowering you to have full control over your processes.

Metal Seated series

Our MS series is essentially the same as our standard SV Series but is suitable for applications that require ANSI Class 600 and ANSI 1500 and for temperature ranges from -330°F to a maximum of 1000°F. This makes it ideal for industries that operate in extreme temperature conditions, such as oil and gas or chemical processing. 

Quick Sample series

The QS Series has many features of our standard Sample Valve, the Soft Seated SV Series, but with a spring-loaded fail-safe design–a plunger-style piston valve and a quarter-turn for a quick release. The QS Series is an excellent valve for extracting or injecting a media sample quickly and easily. 

Quick Advance series

Our QA series features the same attributes as our standard Sampling Valve, Soft Seated SV series, but with a quick open and close feature. The QA series uses a rack and gear combination to maintain the piston's linear motion and provides the valve with a full piston design while traveling just 1/3  turn. This results in less time and labor required to collect a valid sample.
