Sampling valves

Alfa Laval’s range of hygienic sampling valves are valves used to draw liquid samples for evaluation in hygienic and aseptic processes without contaminating the sample or the sample source. Drawing representative samples that accurately reflect product characteristics enables product control and ensures product safety and quality. Ideal for use across the food, beverage, home-personal care, and biotech and pharmaceutical industries.

Sampling valves

Safe, highly accurate and reliable sampling with exceptional reproducibility and economy for volumes large and small

Representative, contamination-free sampling with various options and accessories, including a double seat valve cleaning functionality

Safe sampling using quality sampling accessories, including pressure relief valves, to assure proper usage and workplace safety

Sterile sampling using quality sampling accessories, including a steam generator or hypodermic needle, to ensure extraction of microbial-free samples

Flexible, easy-to-clean hygienic solutions for manual and/or pneumatic operation in a single sampling valve

Versatile sampling methods, from hypodermic needle and plug to manual or pneumatic solutions with large ports and diaphragm

Whether managing brewery yeast propagation or taking bulk, aseptic or microbiological samples, Alfa Laval sampling valves enable representative sampling in hygienic processes under sterile conditions. High accuracy, exceptional reproducibility and excellent cleanability ensure product quality, safety and integrity whilst eliminating the risk of cross-contamination. This results in increased productivity and yield.

How does sampling valves work?

Alfa Laval sampling valves, including sanitary sample valves and sampling valve stainless steel options, enable the operator to extract a representative portion of the process liquid for analysis to ensure quality control. These sanitary sampling valves are operated either by manual handle, by pneumatic actuator, or by a combination of manual handle and pneumatic actuator. For sterile sampling in pharmaceutical applications, a hypodermic needle is inserted into a rubber membrane plug to draw the process liquid for evaluation, making these pharmaceutical valves ideal for precise and hygienic sampling.
