KEOFITT Valves Classic

Featuring a coaxial, steam-sterilizable design with dedicated inlets for SIP and CIP, this pioneering in-situ sterilizable sampling valve has set the standard for hygienic and microbiological sampling for thirty years. Constantly improved over time, it remains the top choice and best-selling valve on the market. Utilizing KEOFITT®'s patented membrane technology, it is employed daily at over 150,000 sampling points worldwide.

Available in five distinct models and sizes: 4KAI (ID 5 mm), W9 (ID 9 mm), INGOLD, W15 (ID 15 mm), and W25 (ID 25 mm).

Each KEOFITT valve comprises a valve body, diaphragm, and valve head. Selecting and configuring your valve is tailored to your specific needs and preferences. Explore the options below to guide you in choosing the ideal sampling valve for your application.

Classic products

4 KAI

The KEOFITT CLASSIC 4KAI Sampling Valve, the smallest in its line, samples low viscosity products (0-100 cP) with particles under 1.5 mm. Higher viscosity sampling is possible, but slower depending on process pressure.

W9

The KEOFITT CLASSIC W9 is the original steam-sterilizable sampling valve, refined over 40 years and still KEOFITT’s most popular. Ideal for sampling medium viscosity liquids (<1000 cP) with particles <3 mm, it meets diverse liquid sampling needs.

INGOLD

The INGOLD sampling valve fits Ingold® bio-connectors, ideal for sampling liquids with 0-1000 cP viscosity and particles under 2 mm. It efficiently handles most liquid sampling needs, with longer times for more viscous liquids based on process pressure.

W15

The KEOFITT CLASSIC W15 Sampling Valve is ideal for high-viscosity products (0-50,000 cP) with particles up to 8 mm. Sampling thicker liquids is feasible, albeit with extended time required (varies with process pressure).

W25

The KEOFITT CLASSIC W25 Sampling Valve is the largest in its range, ideal for sampling highly viscous products up to 250,000 cP with particles under 17 mm. Sampling thicker liquids may require additional time, influenced by process pressure.
