Since 1974, FAMAT SAMPLING has been a trusted partner for industries requiring precise, hygienic, and contamination-controlled sampling, in compliance with GMP requirement for aseptic environments.
Our sampling systems are designed with a hygienic and drainable product-contact area, can be polished to Ra ≤ 0.4 µm, and are compatible with CIP/SIP processes. Upon request, all product-contact materials are available with FDA and USP Class VI certifications. Complete documentation is provided, including material certificates, declarations of conformity, and traceability.
Our entire range is developed to meet the demanding requirements of aseptic and sanitary processing, thanks to our patented EPT® (Expanding Piston Technology). This unique design minimizes dead space within the product path, eliminates O-rings in product contact, and reliable sealing from vacuum up to 10 bar (145 psi).
With EPT®, the PTFE outer layer of the piston expands within the valve body, providing optimal sealing, eliminating common wear points, and significantly reducing the risk of contamination.
Whether for manual, aseptic, steam-barrier, or pressurized sampling, our valves ensure reliable, safe, and repeatable sampling for the pharmaceutical, biotech, food, beverage, and cosmetics industries, even under demanding process conditions.
Robust sampling valves for high-volume applications. Ideal for powders, granules, pastes, and liquids under pressure or vacuum.
Compact and versatile valves for standard process lines. Perfect for pharmaceutical and chemical sampling in smaller systems.
Specialized valves for gas or micro-quantity liquid sampling. Engineered for precision in high-pressure, high-temperature conditions.
FAMAT sampling valves are designed for the safe and accurate extraction of powders and other challenging process media from reactors, process equipment, and containment systems, without compromising product quality, operator safety, or process integrity.
At the core of our valve design is our patented EPT® (Expanding Piston Technology). When the valve is opened, the PTFE-coated piston retracts, allowing a clean and controlled flow of product for sampling. Once closed, the piston expands outward, creating a perfect vacuum-tight seal, without the need for O-rings or gaskets.
Contact usOur valves are engineered to deliver precise and sterile sampling without risk of cross-contamination. Whether you're handling liquids, semi-solids, or powders, each sample is representative and repeatable, even under challenging pressure or temperature conditions.
The internal geometry eliminates product retention areas, making the valves fully clean-in-place (CIP) and sterilize-in-place (SIP) compatible. This ensures effortless maintenance and consistent hygiene, batch after batch.
From manual to pneumatic actuation, our valves support multiple sampling methods — including pressure, membrane-sealed, steam-barrier, and powder sampling. Flexible integration with accessories like sampling bottles, pressure relief devices, or sterile connectors ensures adaptability across all process types.
Built from high-grade stainless steel and engineered to withstand full vacuum to 10 bar pressure and temperatures up to 300°C, FAMAT valves offer long service life and safe performance in the most demanding environments.
With over 50 years of engineering experience, FAMAT delivers sampling solutions trusted by pharmaceutical, biotech, food, and cosmetics manufacturers around the world. We combine innovation, reliability, and precision, every valve, every time.
Our patented Expanding Piston Technology (EPT®) is a globally recognized innovation that enables safe, sterile, and highly accurate sampling, with zero risk of cross-contamination.
Piston expands against the valve walls – ensuring a perfect seal and eliminating product retention.
No O-rings or sealing seats – removing common contamination risks and simplifying maintenance.
