Sample Valves

Sampling Valves are valves dedicated to drawing a live sample from process piping. They also can be used for injection purposes. They are frequently used in many industrial processes involving liquids and gasses to ensure the product quality meets standards.

Samples can be taken in several ways, including using a ball valve to fill an open container. The issue with this approach is that there is little to no safety measures involved with a strategy to protect operators from the process. An open container adds the possibility of product surplus and spills that can harm and impose health risks to 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.

STRAHMAN HAS THE SOLUTION: Sampling Valves that extract fluid directly from the pipeline, taking safe samples without failure – under high pressure or high vacuum conditions.

Our Sampling Valves come in three different series:

SV series

This Soft Seated series is our This Sampling Valve series is our standard series with a non-clogging design (no dead space) and an opening indicator for safe user extraction. The SV series also provides a reliable live sample as the one-piece piston fills the valve cavity. The SV series is used for both sampling and injection applications and can be customized to meet an entire facility's applications.;

MS series

Our Metal Seated Series is dimensionally the same as our standard SV Series but is suitable for ANSI Class 600, 1000°F applications. 

QA series

Our Quick Advance Piston series with features of our standard valves with a quick open/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 true, representative sample.

Strahman takes pride in offering a complete sampling valve system to provide safe, repeatable, live samples for your process. To learn more about our Sampling Valves and the bottles and adapters we can offer, contact us here.
